[0002] Battery performance is an important indicator for measuring the performance of electronic devices. To objectively and effectively monitor and evaluate the performance of battery charging schemes in actual applications, it is necessary to integrate a charging data point feedback mechanism, aiming to sort out the baseline of charging experience indicators and incorporate them into the planning, control, and improvement of charging services. Therefore, the design of battery charging data points has become a key point in monitoring and evaluating battery charging schemes. If the existing charging data point design is unreasonable and a lot of useless information is designed, it will make it impossible to accurately analyze the charging scheme. Therefore, optimizing the charging data point design scheme has become an urgent technical problem to be solved. Summary of the Invention

[0028] In order to understand the features and technical content of the embodiments of the present application in more detail, the implementation of the embodiments of the present application will be described in detail below with reference to the accompanying drawings. The accompanying drawings are only for reference and illustration, and are not used to limit the embodiments of the present application.

[0029] Figure 1 Schematic diagram of the first process of the charging information detection method in the embodiments of the present application. As Figure 1 shown, the method may specifically include:

[0030] Step 101: Record charging information when the electronic device establishes a connection with the charger;

[0031] In practical applications, the electronic device establishes a wired or wireless connection with the charger, and records the charging information generated during the charging process when the connection starts. The charging information includes one or more pieces of information related to the charging performance during the current charging process.

[0032] Exemplarily, charger type, adapter type, charging power, information recorded at the start of charging, information recorded during the charging process.

[0033] Specifically, the charger type includes: wired, wireless, and unknown;

[0034] The adapter type includes: wired adapter type, wireless adapter type;

[0035] The information recorded at the start of charging includes: initial battery level, initial temperature;

[0036] The information recorded during the charging process includes: maximum temperature, screen-on time, screen-off time, charging capacity at the first preset time, average charging speed, total charging time when fast charging is full, total time for the full-charge icon to disappear, total charging cut-off time, reason for full charge, current-limiting statistical information.

[0037] Step 102: Obtain the charging time when the electronic device disconnects from the charger;

[0038] Here, the charging time refers to the time between when the electronic device is connected to the charger and when it is disconnected.

[0039] Step 103: When the charging time is greater than or equal to the first time, determine the information type of the charging information, and generate charging buried point information based on the information type and the charging information, where the information type includes one of the following: non-charging information, slow charging information, and normal charging information;

[0040] Here, the charging time being greater than or equal to the first time is a prerequisite for allowing the determination of the charging information type and for allowing the reporting of charging buried point information. The charging time being greater than or equal to the first time means that when the charging time is sufficient, the recorded charging information can represent a charging process, and analyzing the charging information can obtain an accurate analysis result of the charging process and upload valid charging buried point information.

[0041] Exemplarily, in some embodiments, the method further includes: when the charging time is less than the first time, determining that the charging information is invalid information. That is, when the charging time is short, the recorded charging information is not sufficient to represent a charging process, and analyzing the charging information cannot obtain an accurate analysis result of the charging process. Therefore, it is defined as invalid information and not uploaded, thereby improving the accuracy of the charging process analysis and avoiding uploading invalid information.

[0042] Exemplarily, the first time can be 1 minute, 2 minutes, 3 minutes, 4 minutes, 5 minutes, or other time.

[0043] Exemplarily, in some embodiments, the determining the information type of the charging information includes: obtaining the time when the charging current value of the battery is greater than 0 in the charging state and the total charging time; when the ratio of the time when the charging current value is greater than 0 to the total charging time is greater than a first preset ratio, determining that the charging type is non-charging.

[0044] Exemplarily, in some embodiments, the determining the information type of the charging information includes: obtaining the charger type and the adapter type; when the charger type is unknown or the adapter type is unknown, determining that the information type is slow charging information;

[0045] When the charger type is known and the adapter type is known, obtain a corresponding charging speed reference table based on the charger type and the adapter type, where the charging speed reference table includes reference currents corresponding to at least two power ranges; obtain the increased power and charging time of the battery in the first power range, where the first power range is any one of the at least two power ranges; divide the increased power of the battery by the charging time to obtain the average current in the first power range; if the average current in the first power range is less than the reference current in the first power range, determine that the information type is slow charging information.

[0046] That is to say, when the charger type is unknown or the adapter type is unknown, it is determined that the charging is slow; when the charger type is known and the adapter type is known, for different charging schemes, if the average current in different power ranges is less than the reference current, it is determined that the charging is slow.

[0047] Exemplarily, in some embodiments, the method further includes: obtaining the reference charging time in the first power range; if the charging time in the first power range is greater than the reference charging time and the average current in the first power range is less than the reference current in the first power range, determine that the information type is slow charging information.

[0048] That is to say, in addition to the average current in different power ranges being less than the reference current, the charging time also needs to be greater than the reference charging time to be determined as slow charging. Exemplarily, the charging speed reference table may further include reference charging times corresponding to at least two power ranges.

[0049] Further, in some embodiments, the method further includes: when the charger type is known and the adapter type is known, if a corresponding charging speed reference table cannot be obtained based on the charger type and the adapter type, determine that the information type is not slow charging information.

[0050] Exemplarily, in some embodiments, the method further includes: when it is determined that the information type is neither no charging information nor slow charging information, determine that the information type is normal charging information.

[0051] It should be noted that in the embodiments of the present application, the priority of judging no charging is higher than the priority of judging slow charging, and the priority of judging slow charging is higher than the priority of judging normal charging information. That is to say, first judge no charging, and if it is determined that there is no charging, generate no charging buried point information and upload it; when it is determined that charging is occurring, judge slow charging, and if it is determined that the charging is slow, generate slow charging buried point information and upload it; when it is determined that the information type is not slow charging information (that is, it is determined that the information type is normal charging information), generate normal buried point information and upload it.

[0052] Step 104: Upload the charging buried point information.

[0053] It should be noted that only one charging buried point information is uploaded during one charging process, and there will be no repeated upload.

[0054] Exemplarily, in some embodiments, uploading the charging buried point information includes: uploading the charging buried point information after delaying for a second preset time; wherein, when the information type is non-charging information, the second preset time is the second time; when the information type is slow charging information, the second preset time is the third time; when the information type is normal charging information, the second preset time is the fourth time.

[0055] In practical applications, the second time, the third time, and the fourth time may be the same or different. Exemplarily, they are all 1s, 1.5s, 2s, 5s, 10s, 12s, etc., or the second time is 1.5s or 7s, and the third time and the fourth time are 12s.

[0056] Exemplarily, in some embodiments, the method further includes: within the second preset time, when it is determined that there is an interruption in the charging between the electronic device and the charger, the charging buried point information is not uploaded; within the second preset time, when it is determined that there is no interruption in the charging between the electronic device and the charger, the charging buried point information is uploaded.

[0057] That is to say, uploading the charging buried point information after delaying for the second preset time is to determine whether there is an interruption in the charging. Only when there is no interruption in the charging is it uploaded. In order to avoid uploading the charging buried point information multiple times due to an interruption in the charging, and the second preset time is sufficient for the reconnection of the interrupted charging. In practical applications, if there is an interruption, the interrupted buried point information can also be uploaded.

[0058] Exemplarily, the method further includes: recording the change time when the charging voltage changes from the normal voltage to 0v and then from 0v to the normal voltage; when the change time is less than the third preset time, it is determined that there is an interruption; when the change time is greater than or equal to the third preset time, it is determined that there is no interruption. Here, the interruption can be understood as an abnormal disconnection that is not a user behavior. For example, the charging voltage changes from 5v to 0v and then from 0v to 5v in a very short time.

[0059] By adopting the above technical solution, only when there is enough charging time can enough charging information be obtained to represent one charging process, and the charging information type (including non-charging / slow charging / normal information) can be judged. The charging buried point information is generated using the information type and the charging information for uploading, which is used for further accurate analysis of the charging information. And only one buried point information is uploaded during one charging process, and there will be no repeated upload.

[0060] To better illustrate the purpose of this application, based on the above embodiments of this application, a further example of the charging information detection method will be given.

[0061] The charging information to be specifically monitored includes the following:

[0062] 1. Charger type (Power_mode), adapter type (adapter_type), and charging power (power), which are represented by strings during charging. Specifically,

[0063] Power_mode: Used to distinguish between wireless and wired power supply types. The default is unknow, wired is wired, wireless is wireless, or abbreviated as "wls".

[0064] When Power_mode is wired, there will be three fields: namely adapter_type\adapter_id (if any)\power

[0065] When Power_mode is wireless, there will be three fields: namely adapter_type\dock_type (if any)\power

[0066] Specifically, according to the adapter type (adapter_type), its fields are as follows:

[0067] (1) When the charger type is not recognized (power_mode = "unknow"), it is represented by the string: $$power_mode@@unknow. When generating charging buried point information, different charging information is separated by a first separator, and the charging information includes the information name and the specific content, and the information name and the specific content are separated by a second separator. Here, "$$" is the first separator, and "@@" is the second separator;

[0068] (2) When the charger type is recognized as wired and the adapter type is sdp or cdp or dcp, it is represented by the string:

[0069] $$power_mode@@wired$$adapter_type@@sdp$$power@@2500 or

[0070] $$power_mode@@wired$$adapter_type@@cdp$$power@@7500 or

[0071] $$power_mode@@wired$$adapter_type@@dcp$$power@@10000

[0072] (3) When it is recognized that the charger type is wired and the adapter type is pd or qc or pps or ufcs, it is represented by a string as:

[0073] $$power_mode@@wired$$adapter_type@@pd$$power@@18000 or

[0075] $$power_mode@@wired$$adapter_type@@pps$$power@@30000 or

[0076] $$power_mode@@wired$$adapter_type@@ufcs$$power@@100000

[0077] Among them, the default power of pps is 30000 milliwatts, and the default power of ufcs is 100000 milliwatts. Each project can configure the charging power according to its actual project.

[0078] (4) When it is recognized that the charger type is wired and the adapter type is a fast charging adapter, it is represented by a string as:

[0079] $$power_mode@@wired$$adapter_type@@xxx$$adapter_id@@xxx$$power@@xxx where

[0080] Adapter_type is vooc or svooc

[0081] Adapter_id is the id code sent by the adapter. For example, the 65W fast charging adapter is 0x14

[0082] Power is the power supported by each fast charging adapter.

[0083] (5) When it is recognized that the charger type is wireless and the adapter type is bpp or epp, it is represented by a string as:

[0084] $$power_mode@@wls$$adapter_type@@bpp$$power@@5000 or

[0085] $$power_mode@@wls$$adapter_type@@epp$$power@@10000

[0086] (6) When wireless VOOC / SVOOC is recognized:

[0087] $$power_mode@@wls$$adapter_type@@xxx$$dock_type@xxx$$power@@xxx

[0088] Adapter_type is airvooc or airsvooc

[0089] The dock type (Dock_type) is model_0 - model_15, "third_party", that is, for wireless charging, the charging information also includes the dock type

[0090] Power is the maximum power received by the A2 code

[0091] 2. Information recorded at the start of charging:

[0092] The initial battery level at the start of charging: $$start_soc@@xxx

[0093] The initial temperature at the start of charging: $$start_temp@@xxx

[0094] 3. Information recorded during charging:

[0095] The highest temperature (max_temp) during charging: $$max_temp@@xxx

[0096] The total time with the screen on and the total time with the screen off (ledon_time): $$ledon_time@@xxx$$ledoff_time@@xxx

[0097] The charging capacity in 5 minutes (chg_five_mins_cap): $$chg_five_mins_cap@@xxx (This field is not available if the charging time is less than 5 minutes)

[0098] The charging capacity in 10 minutes (chg_ten_mins_cap): $$chg_ten_mins_cap@@xxx (This field is not available if the charging time is less than 10 minutes). Here, 5 minutes and 10 minutes refer to the first preset time.

[0099] Average charging speed (chg_average_speed): $$chg_average_speed@@xxx (mAh increased per minute during the period when wireless or wired fast charging is fully charged / normal charging is stopped / disconnected)

[0100] Total charging time when fast charging is fully charged (fast_full_time): $$fast_full_time@@xxx (From the start time of charging to the time when wireless or wired fast charging reports full charge. For wired charging, it reports "full", and for wireless charging, it is the moment when it switches to ffc. If it is not fast charging or does not report full charge when disconnected, this field does not exist.)

[0101] Total time for the full charge icon to disappear (report_full_time): $$report_full_time@@xxx (This field exists only when it reports full charge). From the start time of charging to the time when the full charge icon disappears. This period includes fast charging and part of the normal charging time;

[0102] Total charging time until charging is stopped (normal_full_time): $$normal_full_time@@xxx (The total continuous time when charging is truly stopped). From the start time of charging to the time when fast charging reports full charge, and then to the time when it is truly fully charged after switching to normal charging.)

[0103] Reason for reporting full charge (full_reason): $$@@xxx, full_reason includes full charge under normal conditions (full_normal), full charge at low temperature (full_low_temp), full charge at high temperature (full_high_temp), third-party battery (full_third_batt), no battery (full_no_batt),

[0104] Current limiting statistical information. To control the temperature of the electronic device, the charging current is limited. Exemplarily, the charging current is divided into 32 levels (cool_down). The charging current level is determined according to the temperature of the electronic device, and the proportion of each level of cool_down in the total charging time is statistically calculated. It is represented as a string: $$cool_down@@L_0, XXX;...; L_31, XXX.

[0105] In practical applications, the charging information may also include other information (other), represented as a string: $$other@@xxx. Exemplarily, the other information may be the information of the print log (print_log) for development.

[0106] The type_reason (information type) of the non-charging buried point information is no_charging (not charging). When there is no need to judge the specific reason, the flag_reason (reason identifier) is no_charging.

[0107] The type_reason of the slow-charging buried point information is Charger_slow (slow charging), and the flag_reason is BattTempWarm (high battery temperature), BattTempCold (low battery temperature), BattCapHighWhenPlugin (high battery power when starting to charge), CoolDownCtlLongTime (long current-limiting time), or Other (others).

[0108] The type_reason of the normal charging buried point information is general_record (normal information). When there is no need to judge the specific reason, the flag_reason is ChargerInfo (charging information).

[0109] In the embodiments of the present application, the standard for judging whether it is not charging is as follows:

[0110] If the time ratio of the charging current value (Icharging) of the battery in the current charging state (Prop_status = charging) being greater than 0 to the total charging time exceeds 70%, it is determined that it is not charging. Here, the absolute values of the charging current value and the discharging current value are the same, but the sign of the charging current value is positive, and the sign of the discharging current value is negative.

[0111] Figure 2 It is a schematic flow diagram of non-charging detection in the embodiments of the present application. As Figure 2 shown, the specific judgment process is as follows:

[0112] 1. When starting to charge and the charger is not disconnected, judge whether the charging start identifier Track_reset = true? If Track_reset = true, start recording the starting temperature, power, starting time, starting capacity, and start the threads for monitoring the charging speed at 5 minutes and 10 minutes, and set Track_reset = false;

[0113] 2. If Track_reset = false, obtain the charger type and count the screen-on time, average charging speed, charging capacity at 5 minutes and 10 minutes, full charge time, and cool_down statistics; determine whether it is truly in the charging state (charing); when prop_status = charing, record the total charging time, i.e., Chg_total_cnt; and record the time when the charging current value (Icharging)>0, i.e., No_charging_cnt.

[0114] 3. When the charger is disconnected, determine whether the connection charger time (i.e., the charging time) exceeds 2 minutes; if it does not exceed 2 minutes, the current charging information is invalid and not uploaded; if it exceeds 2 minutes, determine whether it is not charging, i.e., if chg_total_cnt is equal to 0, directly record the non-charging return value ret = true to indicate non-charging. If the ratio of no_charging_cnt to chg_total_cnt exceeds 70%, temporarily record the non-charging return value ret = true to indicate non-charging, otherwise record ret = false to indicate charging. Finally, turn on the debug debugging node and set debug_no_charging to true, then judge that the non-charging return value ret = true.

[0115] 4. When the return value is equal to true, it is judged that there is no charging. When disconnecting, the priority of judging no charging is the highest. In the case of no charging, the sensitive information to be pre-uploaded this time will be packaged, and then the work of the no-charging buried point will be called after a delay of 1.5 seconds or 7 seconds. The previously packaged sensitive information will be uploaded to the server. The waiting time is because this disconnection may be intermittent, so this buffer time needs to be waited to determine whether it is intermittent. After determining that it is not intermittent, it will be uploaded. If it is judged to be intermittent, then the work of the current non-charging upload will be cancelled in the code where it is judged to be intermittent.

[0116] 5. Since the logic of no charging is difficult to trigger, a test debug node is provided. Echo 1>debug_no_charging can trigger it.

[0117] Exemplarily, the format of the no-charging buried point information is as follows:

[0118] Oplus Charger, charge_monitor, payload@@charge_monitor$$type_reason@@no_charging$$flag_reason@@no_charging$$time@@[2022-01-13 12:38:10]$$power_mode@@wired$$adapter_type@@sdp$$power@@2500$$start_soc@@0$$start_temp@@279$$max_temp@@283$$led_on_pct@@0$$chg_five_mins_cap@@0$$chg_ten_mins_cap@@1$$chg_average_speed@@0$$fast_full_time@@60$$report_full_time@@60$$normal_full_time@@60$$full_reason@@full_normal$$cool_down@@L_0,1520;L_1,0;L_2,0;L_3,0;L_4,0;L_5,0;L_6,0;L_7,0;L_8,0;L_9,0;L_10,0;L_11,0;L_12,0;L_13,0;L_14,0;L_15,0;L_16,0;L_17,0;L_18,0;L_19,0;L_20,0;L_21,0;L_22,0;L_23,0;L_24,0;L_25,0;L_26,0;L_27,0;L_28,0;L_29,0;L_30,0;L_31,0$$other@@CHGR[0 0 0 3 0],BAT[1 0 0 0 1 0],GAUGE[275 3707 3693 -217 -1 3 3 17 128 4386],STATUS[0 0 0 0 0 0x0 0 0 0],OTHER[0 1 0 0 0 0]$$Time@@1642048690。

[0119] By adopting the above non-charging detection method, the actual non-charging situation of the electronic device can be accurately detected, that is, it can well detect the abnormal rate of non-charging due to device abnormalities or software failures, providing data support for the statistical analysis and early warning of the non-charging abnormal mechanism.

[0120] In the embodiment of the present application, the criterion for determining whether the charging is slow is: if the average current in different power ranges is less than the reference current, it is determined that the charging is slow, and further the reason for the slow charging is judged.

[0121] First, define a charging speed reference table for different power ranges under different charger types and adapter types. Specifically, the charging speed reference table for the wired charger type is shown in Table 1. The first column in it is the maximum power supported by the electronic device. That is to say, this method further includes: when the charger type is known and the adapter type is known, based on the charger type and the maximum power supported by the electronic device, obtain the corresponding charging speed reference table.

[0122] Table 1

[0123]

[0124] The charging speed reference table for the wireless charger type is shown in Table 2:

[0125] Table 2

[0126]

[0127] Among them, the software needs to configure the wired and wireless solutions in dtsi. Then the software code finds the charging speed reference table for judging slow charging through the index of dtsi, and then calculates the average current in each power range of 0 - 50% \ 50% - 75% \ 75% - 90%. The average current = the increased battery power in the power range / the charging time. When the average current is less than the reference current in the corresponding power segment, as long as one power range is satisfied, it is judged that the charging is slow, and further judge the reason for the slow charging.

[0128] Specifically, the average current = the increased battery power in each power range / the charging time = (the battery power at 90% when disconnected - the battery power when connected) / the charging time.

[0129] Figure 3 This is the schematic diagram of the first part of the process for detecting slow charging in the embodiments of this application. As Figure 3 shown, the steps for detecting slow charging include:

[0130] 1. When the buried point drive is loaded, it will parse the index of the charging speed reference table used for calculating the wired \ wireless fast charging \ wireless EPP \ wireless BPP configured in dtsi; the reference table of the average current for slow charging of various solutions has been pre-configured in the software code. Then map the index to the pointer of the speed reference table. It is necessary to determine whether the configured index is illegal. If it is determined to be legal within the array length range, directly assign the corresponding speed reference table pointer to the entity. Therefore, the software needs to configure the index in dtsi. If it is determined to be illegal outside the array length range, the corresponding charging speed reference table pointer remains the default NULL.

[0131] 2. When the charger is disconnected, check if the connection time of the charger (i.e., the charging time) exceeds 2 minutes. If it does not exceed 2 minutes, the current charging information is invalid and not uploaded. If it exceeds 2 minutes, a judgment on slow charging will be executed (see Figure 5 ). If it is determined that the charging is slow, the sensitive information to be pre-uploaded this time will be packaged. When the charger type is wireless, the work of the slow charging buried point information will be called and uploaded after a 7-second delay. When the charger type is wired, the work of the slow charging buried point information will be called and uploaded after a 1.5-second delay.

[0132] Figure 4 This is the schematic diagram of the second part of the slow charging detection in the embodiment of the present application, which executes the judgment of slow charging and also includes the judgment of the reason for slow charging.

[0133] 3. When the charger is connected, the increased battery power mah in the low battery power segment of 0%-50%, the medium battery power segment of 50%-75%, and the high battery power segment of 75%-90% will first be converted into mas per single cell and in seconds. If Power_type = unknow (the charger type is unknown), it is directly determined that the charging is slow (Chg_slow = true). If Power_type = wls (the charger type is wireless) and adapter_type = unknow (the adapter type is unknown), it is directly determined that the charging is slow;

[0134] 4. If Power_type = wls, if adapter_type = unknow, it is directly determined that the charging is slow; if adapter_type = epp, check if the reference speed pointer of epp is NULL. If it is NULL, it is determined that the charging is not slow (Chg_slow = false); otherwise, calculate the charging speed using the reference speed table of epp. Then, check if the duration in the low / medium / high battery power intervals is 0. If all are 0, it is determined that the charging is slow; if the duration in the low battery power segment exceeds 6 seconds and the increased power in the low battery power segment / the duration in the low battery power segment < the average current in the low battery power segment of the reference table, it is determined that the charging is slow; if the duration in the medium battery power segment exceeds 8 seconds and the increased power in the medium battery power segment / the duration in the medium battery power segment < the average current in the medium battery power segment of the reference table, it is determined that the charging is slow; if the duration in the high battery power segment exceeds 10 seconds and the increased power in the high battery power segment / the duration in the high battery power segment < the average current in the high battery power segment of the reference table, it is determined that the charging is slow.

[0135] If Power_type = wls, and if adapter_type = bpp, then determine whether the reference speed pointer of bpp is NULL. If it is NULL, then it is determined as not slow charging; otherwise, calculate the charging speed and select the reference speed table of bpp; then determine whether the duration of the low / mid / high battery level intervals is 0. If all are 0, then it is determined as slow charging; if the duration of the low battery segment exceeds 6s and the increased battery power in the low battery segment / the duration of the low battery segment < the average current in the low battery segment of the reference table, then it is determined as slow charging; if the duration of the mid battery segment exceeds 8s and the increased battery power in the mid battery segment / the duration of the mid battery segment < the average current in the mid battery segment of the reference table, then it is determined as slow charging; if the duration of the high battery segment exceeds 10s and the increased battery power in the high battery segment / the duration of the high battery segment < the average current in the high battery segment of the reference table, then it is determined as slow charging.

[0136] If Power_type = wls, and if adapter_type = airvooc\airsvooc, then determine whether the reference speed pointer of airvooc\airsvooc is NULL. If it is NULL, then it is determined as not slow charging; otherwise, calculate the charging speed and select the reference speed table of air vooc\airsvooc; then determine whether the duration of the low / mid / high battery level intervals is 0. If all are 0, then it is determined as slow charging; if the duration of the low battery segment exceeds 6s and the increased battery power in the low battery segment / the duration of the low battery segment < the average current in the low battery segment of the reference table, then it is determined as slow charging; if the duration of the mid battery segment exceeds 8s and the increased battery power in the mid battery segment / the duration of the mid battery segment < the average current in the mid battery segment of the reference table, then it is determined as slow charging; if the duration of the high battery segment exceeds 10s and the increased battery power in the high battery segment / the duration of the high battery segment < the average current in the high battery segment of the reference table, then it is determined as slow charging.

[0137] If Power_type = wired (the charger type is wired), determine whether the wired reference speed pointer is NULL. If it is NULL, then it is determined as not slow charging; otherwise, calculate the charging speed and select the wired reference speed table; then determine whether the duration of the low / mid / high battery level intervals is 0. If all are 0, then it is determined as slow charging; if the duration of the low battery segment exceeds 6s and the increased battery power in the low battery segment / the duration of the low battery segment < the average current in the low battery segment of the reference table, then it is determined as slow charging; if the duration of the mid battery segment exceeds 8s and the increased battery power in the mid battery segment / the duration of the mid battery segment < the average current in the mid battery segment of the reference table, then it is determined as slow charging; if the duration of the high battery segment exceeds 10s and the increased battery power in the high battery segment / the duration of the high battery segment < the average current in the high battery segment of the reference table, then it is determined as slow charging.

[0138] 5. When it is judged that the charging is slow, it is necessary to judge the reason for the slow charging. The triggering reasons are as follows according to the priority:

[0139] (1) Has the battery been high temperature or low temperature during charging?

[0140] Flag_reason (reason for slow charging): BattTempWarm (high battery temperature) / BattTempCold (low battery temperature)

[0141] (2) Is the charger type unknown, or is the power of the wired charger less than the maximum wired power supported by the mobile phone in this project, or is the maximum power of the wireless charger less than the maximum wireless power supported by this project - 10W when it is not EPP and not bpp?

[0142] flag_reason: NonStandardAdatpter (non-standard adapter)

[0143] (3) Is the battery level at the start of charging higher than 90%? flag_reason: BattCapHighWhenPlugin (high battery level when starting to charge)

[0144] (4) Does the time of the Cool_down function exceed 70%? flag_reason: CoolDownCtlLongTime (long current limiting time)

[0145] (5) If the time of the Cool_down function does not exceed 70%, for other reasons OTHER, flag_reason: Other (other).

[0146] Figure 5 This is the schematic diagram of the third part of the process for detecting slow charging in the embodiments of this application and the information recorded during the charging process.

[0147] 6. When the charger is connected for charging, it depends on the charging 5s thread to perform the statistical work of each parameter in the charging process every 5s. When the battery temperature is not high temperature / not low temperature, that is, no high temperature or low temperature is recorded and the battery temperature enters the high temperature range or low temperature range, then the flag of high battery temperature or low battery temperature is set to true. This flag is required when judging the reason for slow charging when the charger is disconnected; count the effective Cool_down time, that is, count when Cool_down>0, and count the time of Cool_down>0 when disconnected or fully charged, and count the increased battery power in each power segment to facilitate the statistics of the reason for slow charging.

[0148] 7. Determine whether the battery reports full charge. If it reports full charge, do not continue to count the increased battery power in each power range. If it does not report full charge, that is, in the charging state, then at the beginning of charging, the power range section_status = DEFAULT. Then, the initial values of the increased battery power and duration in each power range segment are set to the default value 0, and the initial time go_time and initial battery power go_rm are recorded when switching to the next state. This is to accurately count the increased battery power and duration in each power range when the value of section_status is different and the state switches repeatedly. Subtract the initial battery power go_rm from the current battery power, and subtract the initial time go_time from the current time.

[0149] 8. Section_status has 5 states. DEFAULT is the default state, LOW corresponds to the power range of 0 - 50%, MEDIUM corresponds to the power range of 50% - 75%, HIGH corresponds to the power range of 75% - 90%, and OVER corresponds to the power above 90%. Adjacent two states can switch. For example, when the connected power is 20%, continuously count the increased battery power and duration from 20% to 50%. Then, when it reaches 50%, it switches to the MEDIUM state and will re - count the increased battery power and duration from 50% to 75%. The same applies to other cases. Its function: oplus_chg_track_cal_section_soc_inc_rm().

[0150] Figure 6 is the schematic diagram of the power range switching process in the embodiment of this application. As Figure 6 shown, whenever the power range section_status = low, that is, for 0 - 50 in real - time, calculate the increased battery power and duration in this section. First, settle the increased battery power and duration in this range segment (subtract the initial battery power go_rm from the current battery power, and subtract the initial time go_time from the current time). When section_status changes from low to medium, update go_time and go_rm for entering the next state, and calculate the increased battery power and duration when section_status = medium. The same principle applies to the switching of other power ranges.

[0151] Exemplarily, the slow - charging buried - point information format is as follows:

[0153] Using the above charging slow detection method, it can accurately identify slow charging and can well classify the reasons for slow charging in case of slow charging; secondly, the reported buried point data of slow charging can provide data support for the statistical analysis and early warning of the abnormal mechanism of slow charging.

[0154] Figure 7 This is the schematic diagram of the first part of the process for detecting conventional information in the embodiment of the present application, as Figure 7 shown,

[0155] 1. When the charger is disconnected, check if the connection time (i.e., charging time) exceeds 2 minutes. If it does not exceed 2 minutes, the current charging information is invalid and not uploaded. If it exceeds 2 minutes, it is considered a valid charge. Then, check if there was a fast charge full report or a normal charge full report before disconnection. If there was, the average charging speed is not calculated at the time of disconnection because it was already calculated at the time of the full report. If there was no full report, subtract the battery level at the connection time from the battery level at the disconnection time to get the increased battery level during this period. Then, divide the increased battery level by the total charging time to get the average charging speed, i.e., the increased mah per unit time (min). Before uploading, first check if this is a non - charging or slow - charging situation. The judgment priority of normal charging information is the lowest. Only when the non - charging and slow - charging conditions are not triggered, it is determined as normal charging information and the normal charging information is uploaded. The reported information is connected and packed into a single sensitive string to generate normal buried - point information, and delay work is started. The work for uploading the normal buried - point information is called and uploaded 12 seconds later. The reason for not uploading immediately is that it is necessary to check for charging interruption. Only when it is determined that there is no charging interruption is the current buried - point information uploaded, and 12 seconds is enough time for the charging interruption connection.

[0156] If the non - charging and slow - charging conditions are triggered, the buried - point information of non - charging / slow - charging is reported.

[0157] 2. Regardless of whether it exceeds 2 minutes at the time of disconnection, set track_reset = true. This track_reset = true facilitates recording the starting temperature / battery level / starting time / starting capacity at the next connection and starting the threads for monitoring the charging speed at 5 minutes and 10 minutes. Also, the time marker exceeding 2 minutes is reset, so that the timing can start again at the next connection. Because it is possible that the time from connection to disconnection does not meet 5 minutes or 10 minutes, the threads for recording the charging capacity at 5 minutes and 10 minutes need to be cancelled after disconnection. Finally, the status related to buried - point is reset to the default value.

[0158] 3. When starting to charge and the charger is not disconnected, check if the charging start flag Track_reset = true? If Track_reset = true, start recording the starting temperature / battery level / starting time / starting capacity and start the threads for monitoring the charging speed at 5 minutes and 10 minutes, and set Track_reset = false.

[0159] 4. If Track_reset = false, obtain the charger type. When Power_type = wired (the charger type is wired), the wired charger first obtains the basic sdp / cdp / dcp types, then obtains the enhanced pd / qc / pps / ufcs types, and then obtains the fast_chg_type fast charging type. Then, match these type numbers to the corresponding strings to obtain the structure type of power_info, including character information such as power_mode / adapter_type / power. Similarly, for wireless charging, first obtain the adapter_type, then obtain the dock_type, and finally obtain the maximum power supported by the dock. Here, to be compatible with the new wireless architectures of fussi / YingShi and baize, the linux version number is used for differentiation.

[0160] Figure 8 This is the schematic diagram of the second part of the regular information detection process in the embodiment of the present application. As Figure 8 shown, continue to execute starting from Figure 7 node ① in

[0161] 5. Replace the maximum charging temperature (case temperature) in real time during the charging process; count the proportion of each cool_down. First, it will be judged whether the value of cool_down is within the legal range of 0 - 31. If it is and the device is also in the charging state (Prop_status == charging), then the time of the corresponding cool_down will be incremented by 1; then count the proportion of the screen-on time. If the device is in the charging state and the screen is on (led_on = 1), then the recorded screen-on time will be incremented by 1.

[0162] 6. If the device is not in the charging state or the screen is off, count the full charge time. When the fast charging full charge time is equal to the initial value and (wired fast charging is full or wireless switches to ffc or debug is full), then record the duration from connection to fast charging full. If it is less than 1 minute, it will be calculated as 1 minute. At this time, the average charging speed needs to be counted; when reporting full to the system layer and the full charge icon disappears, the total time for the full charge icon to disappear will also be recorded (usually it reports when the duration is 100% for 1 minute). At this time, the reason for the full charge will be counted. Specifically, according to the string in notify containing the full charge attribute, the main reasons for the full charge are counted (normal full charge / high temperature full charge / low temperature full charge / battery not connected / non-standard battery); when the charging actually stops, when the charging_state of wired charging is FULL, or the wls_chg_done of wireless charging or debug is full, then the stop time will be recorded. If it is less than 1 minute, it will be calculated as 1 minute, and the average charging speed from stop to full will be counted.

[0163] 7. Finally, testing can be carried out. Disconnect after connecting for 2 minutes and check whether there is data point uploading and whether the generated data point information meets the expectations.

[0166] By determining which conventional charging information is needed through preliminary research and then how the software monitors and reports this conventional information, the standardization and accuracy of reporting conventional charging data point information are achieved, providing reliable data support for various statistical comparison analyses in the charging field.
