The control circuit (230) can be implemented, for example, as a power management integrated circuit (PMIC) or at least part of an application processor.

[0051] According to one embodiment, the control circuit (230) can check charge state information related to the charging of the battery (189) (e.g., charge / discharge voltage / current, battery life, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheating, short circuit, or swelling). For example, the control circuit (230) can check the signal (voltage or current) at the input or output terminal of the power circuit (210), the matching circuit (211), or the transmitting / receiving circuit (213). The control circuit (230) can determine the state of the battery (189) based on at least some of the checked charge state information. If the state information of the battery (189) is determined to be abnormal, the control circuit (230) can adjust the charging of the battery (189) (e.g., adjust the charging current, adjust the charging voltage, or stop charging). According to one embodiment, the electronic device (101) may include at least one sensor (e.g., a temperature sensor) for checking the charge status of the battery (189). The control circuit (230) may check the charge status of the battery (189) based on data received from the at least one sensor.

[0053] FIG. 3 is a flowchart of a battery power management method according to one embodiment.

[0054] According to one embodiment, the following operations 310 and 320 may be performed by an electronic device (e.g., the electronic device (101) of FIG. 1). The electronic device may include at least some of the components of the electronic device (101) described in FIG. 1 and FIG. 2. For example, the electronic device may include at least one processor (e.g., the processor (120) of FIG. 1) including a processing circuit. The electronic device may include a memory (e.g., the memory (130) of FIG. 1) including one or more storage media for storing instructions. The electronic device may include a power management module (e.g., the power management module (188) of FIG. 1 or the control circuit (230) of FIG. 2) and / or a power circuit (e.g., the power circuit (210) of FIG. 2).

[0055] According to one embodiment, the processor (120) of FIG. 1 may include the control circuit (230) of FIG. 2. For example, the control circuit (230) may be implemented separately from or as part of the main processor (121) of the electronic device.

[0056] As described with reference to FIG. 2, a control circuit (e.g., control circuit (230) of FIG. 2) can perform overall control of a power circuit (e.g., power circuit (210) of FIG. 2). The control circuit can check charge state information related to the charging of a battery (e.g., battery (189) of FIG. 1 and 2). The control circuit can check signals (voltage or current) at the input or output terminals of components of the power circuit (e.g., conductive pattern (219), matching circuit (211), or transmitting / receiving circuit (213) of FIG. 2). The control circuit can determine the state of the battery based on at least some of the checked charge state information. The control circuit can control the charging or discharging of the battery based on at least some of the checked charge state information. The control circuit may be implemented, for example, as a logic circuit, a PMIC, or at least part of an application processor. In the following various embodiments, an operation performed by an ‘electronic device’ or a ‘processor of an electronic device’ may be understood as an operation performed by a ‘control circuit’ that controls a power circuit and / or a circuit related to a battery (e.g., a battery protection circuit included in the battery (189) of FIGS. 1 and 2).

[0057] According to one embodiment, a processor of an electronic device may obtain state data of a battery (e.g., battery (189) of FIG. 1). The state data of the battery may include information on the battery's usage status (e.g., battery capacity, number of charge / discharge cycles, cycle, voltage, or temperature) and / or information related to charging (e.g., charge / discharge voltage / current, battery life, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheating, short circuit, conductivity pattern of a power circuit (e.g., power circuit (210) of FIG. 2), a matching circuit, or a signal (voltage or current) at the input or output terminal of a transmitting / receiving circuit).

[0058] For example, the processor of the electronic device may receive at least some information regarding the battery's usage status and charging from a battery protection circuit (e.g., a battery protection circuit included in the battery (189) of FIG. 1 and 2). The processor of the electronic device may receive at least some information regarding the battery's usage status and charging from a corresponding sensor (e.g., a temperature sensor) among a fuel gauge IC, a power circuit, or a sensor module (e.g., a sensor module (176) of FIG. 1). The processor of the electronic device may obtain at least some information regarding the battery's usage status and charging.

[0059] The electronic device may turn off the power of the electronic device or keep the power on based on the discharge cut-off voltage. The discharge cut-off voltage may represent a voltage (or voltage value) referenced to turn off the power of the electronic device in order to prevent over-discharge of the battery of the electronic device.

[0060] An electronic device can monitor (or check) the battery's status data. The electronic device can monitor the battery's status data, such as, for example, the battery's voltage, current (e.g., discharge current), or temperature. Based on the battery's status data and the discharge cutoff voltage, the electronic device can turn off the power to the electronic device or keep the power on.

[0061] The voltage of the battery of an electronic device may drop sharply, for example, when the load increases, when high-load work is sustained, when the battery ages, when the electronic device is in a low-temperature environment, or when it is connected to an external electronic device requiring high power output (e.g., the electronic device (102) of FIG. 1). As a non-limiting example, when the discharge current of the battery is high, such as when the screen brightness of the electronic device is high, when the electronic device runs multiple apps simultaneously, or when the electronic device performs a high amount of computational work, a significant drop in the voltage of the battery may occur.

[0062] When the voltage of an electronic device's battery drops rapidly, it may temporarily reach the discharge cutoff voltage. If the battery voltage reaches the discharge cutoff voltage due to a high discharge current, there may still be sufficient capacity remaining. Therefore, if the electronic device is turned off without considering the discharge current, the remaining battery capacity cannot be fully utilized, potentially leading to wasted resources.

[0063] An electronic device according to one embodiment may store (or maintain) a discharge profile. The discharge profile may include one or more discharge cutoff voltages and a reference current corresponding to each of the one or more discharge cutoff voltages. The reference current may represent a current (or current value) that is referenced to prevent the power from being turned off even when the remaining capacity of the battery is sufficient when the voltage of the battery reaches any discharge cutoff voltage.

[0064] The electronic device can monitor the battery voltage. The electronic device can determine whether the battery voltage has reached any discharge cutoff voltage of the discharge profile.

[0065] In operation 310, the electronic device can identify that the voltage of the battery of the electronic device has reached the first discharge cutoff voltage of the discharge profile based on a discharge profile comprising one or more discharge cutoff voltages and a reference current corresponding to each of the one or more discharge cutoff voltages.

[0066] In operation 320, the electronic device may turn off the power of the electronic device or keep the power on based on a comparison of a first reference current corresponding to a first discharge cutoff voltage of the discharge profile and the discharge current of the battery.

[0067] The electronic device may turn off the power of the electronic device based on the determination that the discharge current of the battery is less than (or less than) a first reference current corresponding to the first discharge cutoff voltage, as determined that the voltage of the electronic device's battery has reached a first discharge cutoff voltage.

[0068] The electronic device can maintain the power of the electronic device in an ON state based on the determination that the discharge current of the battery is greater than (or exceeds) the first reference current, as determined that the voltage of the electronic device's battery has reached the first discharge cutoff voltage.

[0069] After operation 320, the electronic device may monitor battery status data while keeping the power on. The electronic device may monitor battery status data, such as, for example, the battery voltage, current (e.g., discharge current), or temperature. The operation of monitoring battery status data may be performed in parallel with operations 310 and 320. The operation of monitoring battery status data may be performed continuously after operation 320.

[0070] After operation 320, while the electronic device is kept on, it can identify, based on the discharge profile, that the voltage of the electronic device's battery has reached a second discharge cutoff voltage that is lower than the first discharge cutoff voltage of the discharge profile. Based on a comparison of the second reference current corresponding to the second discharge cutoff voltage of the discharge profile and the discharge current of the battery, the electronic device may turn off the power of the electronic device or keep the power on. A method for turning off the power of the electronic device or keeping the power on by referring to the discharge profile is described in detail with reference to FIG. 4.

[0071] According to one embodiment, operations to turn off or keep the power of the electronic device on based on the discharge profile described above through operations 310 and 320 may be performed in a 'target mode' of the electronic device. The target mode may represent a battery protection mode for turning off or keeping the power on when the voltage of the electronic device's battery reaches an arbitrary discharge cutoff voltage by referring to the discharge profile to prevent over-discharge of the electronic device's battery. The electronic device may monitor the state of charge (SOC) of the battery. The SOC of the battery may represent the remaining capacity of the battery. The SOC of the battery may be obtained by dividing the remaining capacity of the battery by the total capacity. The electronic device may initiate a target mode to turn off or keep the power on based on the discharge profile, based on the battery's SOC satisfying a third defined criterion. The third defined criterion may include conditions corresponding to cases where the battery's SOC is insufficient. For example, the third defined criterion may include a condition in which the battery's SOC is below (or below) a threshold. The electronic device may initiate a target mode when the battery's SOC is below (or below) a threshold (e.g., 50%, 45%, 40%, 35%, or 30%). After the target mode is initiated, the electronic device may perform the aforementioned operations 310 and 320 by determining whether the battery voltage has reached any discharge cutoff voltage of the discharge profile. By initiating the target mode when the battery's SOC is insufficient, the electronic device may avoid unnecessary power consumption required to constantly monitor the battery voltage and discharge profile.

[0072] According to one embodiment, the electronic device may include a plurality of batteries. For example, the battery (189) of FIGS. 1 and FIGS. 2 may be a dual battery type including a first battery and a second battery. The number of batteries included in the electronic device is not limited to the present disclosure, and for example, the electronic device may include a battery system including several batteries, dozens of batteries, or more batteries.

[0073] According to one embodiment, the electronic device may turn off the power or keep the power on by referring to a discharge profile based on the voltage of the first battery among a plurality of batteries. The first battery may be a battery with a larger capacity than another battery, such as the second battery (e.g., a main battery). Among the plurality of batteries, a battery such as the second battery, which is not the first battery, may be a battery that supplies power in situations where the capacity of the first battery is insufficient or power consumption is high (e.g., an auxiliary battery). The electronic device may monitor the voltage of the first battery. The electronic device may determine whether the voltage of the first battery has reached any discharge cutoff voltage of the discharge profile. According to one embodiment, the electronic device may identify that the voltage of the first battery of the electronic device has reached the first discharge cutoff voltage of the discharge profile based on the discharge profile. The electronic device may turn off the power of the electronic device or keep the power on based on a comparison of the first reference current corresponding to the first discharge cutoff voltage of the discharge profile and the discharge current of the first battery.

[0074] According to one embodiment, an electronic device can turn off the power or keep the power on by referring to a discharge profile based on the minimum voltage among the voltages of a plurality of batteries. The electronic device can monitor the voltages of a plurality of batteries. The electronic device can determine whether the minimum voltage among the voltages of a plurality of batteries has reached any discharge cutoff voltage of the discharge profile. According to one embodiment, the electronic device can identify, based on the discharge profile, that the minimum voltage among the voltages of a plurality of batteries of the electronic device has reached a first discharge cutoff voltage of the discharge profile. The electronic device can turn off the power of the electronic device or keep the power on based on a comparison of a first reference current corresponding to the first discharge cutoff voltage of the discharge profile and the discharge current of the battery having the minimum voltage among the plurality of batteries.

[0076] According to one embodiment, the following operations 410 to 460 may be performed by an electronic device (e.g., the electronic device (101) of FIG. 1). The electronic device may include at least some of the components of the electronic device (101) described in FIG. 1 and FIG. 2. For example, the electronic device may include at least one processor (e.g., the processor (120) of FIG. 1) including a processing circuit. The electronic device may include a memory (e.g., the memory (130) of FIG. 1) including one or more storage media for storing instructions. The electronic device may include a power management module (e.g., the power management module (188) of FIG. 1 or the control circuit (230) of FIG. 2) and / or a power circuit (e.g., the power circuit (210) of FIG. 2).

[0077] According to one embodiment, the processor (120) of FIG. 1 may include the control circuit (230) of FIG. 2. For example, the control circuit (230) may be implemented separately from or as part of the main processor (121) of the electronic device.

[0078] As described with reference to FIG. 2, a control circuit (e.g., control circuit (230) of FIG. 2) can perform overall control of a power circuit (e.g., power circuit (210) of FIG. 2). The control circuit can check charge state information related to the charging of a battery (e.g., battery (189) of FIG. 1 and 2). The control circuit can check signals (voltage or current) at the input or output terminals of components of the power circuit (e.g., conductive pattern (219), matching circuit (211), or transmitting / receiving circuit (213) of FIG. 2). The control circuit can determine the state of the battery based on at least some of the checked charge state information. The control circuit can control the charging or discharging of the battery based on at least some of the checked charge state information. The control circuit may be implemented, for example, as a logic circuit, a PMIC, or at least part of an application processor. In the following various embodiments, an operation performed by an ‘electronic device’ or a ‘processor of an electronic device’ may be understood as an operation performed by a ‘control circuit’ that controls a power circuit and / or a circuit related to a battery (e.g., a battery protection circuit included in the battery (189) of FIGS. 1 and 2).

[0080] The electronic device may store (or maintain) a discharge profile comprising one or more discharge cutoff voltages and a reference current corresponding to each of the one or more discharge cutoff voltages. The reference current may represent a current (or current value) referenced to prevent the power from being turned off even when the battery's remaining capacity is sufficient when the battery voltage reaches any discharge cutoff voltage.

[0081] According to one embodiment, the electronic device can generate a discharge profile including one or more discharge cutoff voltages and a reference current corresponding to each of the one or more discharge cutoff voltages. The electronic device can generate a discharge profile based on the internal resistance of the battery of the electronic device and the characteristics of the capacitor elements inside or outside the battery. The electronic device can generate a discharge profile based on the effect of the battery's internal resistance on the voltage drop according to the battery's discharge current (e.g., the current at the output terminal of a power circuit's conductivity pattern, a matching circuit, or a transmitting / receiving circuit). For example, as the battery's internal resistance increases, the voltage drop increases, so the discharge cutoff voltage may be lowered in proportion to the battery's internal resistance. The electronic device can generate a discharge profile based on the performance characteristics of the battery's internal or external capacitor elements that mitigate the voltage drop according to the discharge current. According to one embodiment, the electronic device can pre-store a discharge profile including one or more discharge cutoff voltages and a reference current corresponding to each of the one or more discharge cutoff voltages.

[0082] For example, an electronic device may store a discharge profile such as the following [Table 1]. [Table 1] and the discharge cutoff voltages described below (e.g., the first discharge cutoff voltage (V) cut-off _1), second discharge cutoff voltage (V cut-off _2), third discharge cutoff voltage (V cut-off _3) and the fourth discharge cutoff voltage (V cut-off _4)) and reference current (e.g., first reference current (I ref _1), second reference current (I ref _2), third reference current (I ref _3) and the fourth reference current (I ref The number, value, and / or range of _4)) are exemplary and are not limited to the present disclosure.

[0083] In [Table 1], the second discharge cutoff voltage may be lower than the first discharge cutoff voltage. The third discharge cutoff voltage may be lower than the second discharge cutoff voltage. The fourth discharge cutoff voltage may be lower than the third discharge cutoff voltage.

The second reference current range corresponding to the second discharge cutoff voltage may be 30 mA to 60 mA (or 30 mA or more (or greater) and less than 60 mA (or less than)). The third reference current range corresponding to the third discharge cutoff voltage may be 60 mA to 90 mA (or 60 mA or more (or greater) and less than 90 mA (or less than)). The fourth reference current range corresponding to the fourth discharge cutoff voltage may be 90 mA to 120 mA (or 90 mA or more (or greater) and less than 120 mA (or less)).

[0086] A reference current corresponding to any discharge cutoff voltage may fall within a reference current range corresponding to the discharge cutoff voltage. A first reference current corresponding to a first discharge cutoff voltage may be a value (e.g., 10 mA, 15 mA, or 20 mA) that falls within the first reference current range corresponding to the first discharge cutoff voltage. A second reference current corresponding to a second discharge cutoff voltage may be a value (e.g., 35 mA, 45 mA, or 55 mA) that falls within the second reference current range corresponding to the second discharge cutoff voltage. A third reference current corresponding to a third discharge cutoff voltage may be a value (e.g., 65 mA, 75 mA, or 86 mA) that falls within the third reference current range corresponding to the third discharge cutoff voltage. The fourth reference current corresponding to the fourth discharge cutoff voltage may be a value within the range of the fourth reference current corresponding to the fourth discharge cutoff voltage (e.g., 95 mA, 105 mA, or 110 mA).

[0087] According to one embodiment, the electronic device can update at least a portion of a reference current (or one or more reference currents) corresponding to each of one or more discharge cutoff voltages of a discharge profile based on the temperature of the battery. For example, when the temperature of the battery decreases, the electronic device can sequentially increase the first reference current to 10 mA, 12 mA, 14 mA, etc. within the first reference range.

[0112] According to one embodiment, the discharge profile may include a target discharge cutoff voltage. For example, the target discharge cutoff voltage may represent the lowest discharge cutoff voltage in the discharge profile. For example, the target discharge cutoff voltage may represent a discharge cutoff voltage lower than discharge cutoff voltages having a corresponding reference current (e.g., a first discharge cutoff voltage, a second discharge cutoff voltage, a third discharge cutoff voltage, a fourth discharge cutoff voltage). An electronic device may determine whether the voltage of the battery has reached the target discharge cutoff voltage of the discharge profile. Based on the discharge profile, the electronic device may identify that the voltage of the battery of the electronic device has reached the lowest target discharge cutoff voltage of the discharge profile. If the voltage of the battery has reached the target discharge cutoff voltage of the discharge profile, the electronic device may turn off the power of the electronic device. That is, if the voltage of the battery has reached the target discharge cutoff voltage of the discharge profile, the electronic device may turn off the power of the electronic device regardless of the discharge current of the battery.

[0113] FIG. 5 is a flowchart of a method for updating a discharge profile according to one embodiment.

[0114] According to one embodiment, the following operations 510 and 520 may be performed by an electronic device (e.g., the electronic device (101) of FIG. 1). The electronic device may include at least some of the components of the electronic device (101) described in FIG. 1 and FIG. 2. For example, the electronic device may include at least one processor (e.g., the processor (120) of FIG. 1) including a processing circuit. The electronic device may include a memory (e.g., the memory (130) of FIG. 1) including one or more storage media for storing instructions. The electronic device may include a power management module (e.g., the power management module (188) of FIG. 1 or the control circuit (230) of FIG. 2) and / or a power circuit (e.g., the power circuit (210) of FIG. 2).

[0115] According to one embodiment, the processor (120) of FIG. 1 may include the control circuit (230) of FIG. 2. For example, the control circuit (230) may be implemented separately from or as part of the main processor (121) of the electronic device.

[0116] As described with reference to FIG. 2, a control circuit (e.g., control circuit (230) of FIG. 2) can perform overall control of a power circuit (e.g., power circuit (210) of FIG. 2). The control circuit can check charge state information related to the charging of a battery (e.g., battery (189) of FIG. 1 and 2). The control circuit can check signals (voltage or current) at the input or output terminals of components of the power circuit (e.g., conductive pattern (219), matching circuit (211), or transmitting / receiving circuit (213) of FIG. 2). The control circuit can determine the state of the battery based on at least some of the checked charge state information. The control circuit can control the charging or discharging of the battery based on at least some of the checked charge state information. The control circuit may be implemented, for example, as a logic circuit, a PMIC, or at least part of an application processor. In the following various embodiments, an operation performed by an ‘electronic device’ or a ‘processor of an electronic device’ may be understood as an operation performed by a ‘control circuit’ that controls a power circuit and / or a circuit related to a battery (e.g., a battery protection circuit included in the battery (189) of FIGS. 1 and 2).

[0117] As described with reference to FIG. 3, an electronic device can obtain state data of a battery (e.g., battery (189) of FIG. 1). The state data of the battery may include information on the battery's usage status (e.g., battery capacity, number of charge / discharge cycles, cycles, voltage, or temperature) and / or information related to charging (e.g., charge / discharge voltage / current, battery life, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheating, short circuit, conductivity pattern of a power circuit (e.g., power circuit (210) of FIG. 2), a matching circuit, or a signal (voltage or current) at the input or output terminal of a transmitting / receiving circuit).

[0118] The electronic device may store (or maintain) a discharge profile comprising one or more discharge cutoff voltages and a reference current corresponding to each of the one or more discharge cutoff voltages. The reference current may represent a current (or current value) referenced to prevent the power from being turned off even when the battery's remaining capacity is sufficient when the battery voltage reaches any discharge cutoff voltage.

[0119] An electronic device can update its discharge profile based on the battery cycles. Battery cycles represent the number of times the battery's capacity has been 100% depleted. A higher number of battery cycles can be understood as an indication that the battery has aged or its performance has deteriorated.

[0120] In operation 510, the electronic device can determine whether the cycle of the electronic device's battery satisfies a first defined criterion. The first defined criterion may include a condition corresponding to when the battery has aged to a certain degree as the battery cycles accumulate. For example, the first defined criterion may include a condition in which the battery cycles are above (or exceed) a threshold.

[0121] In operation 520, the electronic device may update the discharge profile by applying a first weight to at least some of the discharge cutoff voltages of the discharge profile based on the fact that the cycle of the electronic device's battery satisfies a first defined criterion. For example, the electronic device may update the discharge profile by applying a first weight to at least some of the discharge cutoff voltages of the discharge profile when the cycle of the battery is greater than (or exceeds) a threshold (e.g., 200 cycles).

[0122] According to one embodiment, the first weight may be a value greater than 1 (or 100%). In a state where the battery cycle satisfies a first defined criterion, i.e., in an aged state, it is necessary to further prevent over-discharge and performance degradation of the battery. The electronic device may turn off the power of the electronic device at a relatively high voltage according to the updated discharge cutoff voltage by multiplying the discharge cutoff voltage of the existing discharge profile by a first weight greater than 1.

[0123] According to one embodiment, the first defined criterion may include a plurality of conditions regarding the battery cycle. For example, the first defined criterion may include a condition in which the battery cycle is greater than or equal to a first threshold (e.g., 200 cycles) (or greater than or equal to the first threshold and less than or equal to a second threshold), a condition in which the battery cycle is greater than or equal to a second threshold (e.g., 500 cycles) (or greater than or equal to the second threshold and less than or equal to a third threshold), and a condition in which the battery cycle is greater than or equal to a third threshold (e.g., 1000 cycles). When the battery cycle is greater than or equal to the first threshold, the electronic device may multiply at least some of the discharge cutoff voltages of one or more of the discharge profile by a first cycle weight (e.g., 1.01). When the battery cycle is greater than or equal to the second threshold, the electronic device may multiply at least some of the discharge cutoff voltages of one or more of the discharge profile by a second cycle weight (e.g., 1.015). The electronic device may multiply a third cycle weight (e.g., 1.017) by at least some of the discharge cutoff voltages of one or more of the discharge profile when the battery cycle is greater than or equal to a third threshold. The electronic device may update the discharge profile by multiplying a corresponding cycle weight by at least some of the discharge cutoff voltages of one or more of the discharge profile when the battery cycle satisfies the aforementioned conditions. The number of conditions, thresholds, and / or weights are exemplary and are not limited to the present disclosure.

[0124] According to one embodiment, the electronic device can update at least some of one or more discharge cutoff voltages of a discharge profile based on the battery cycle. For example, the electronic device can increase at least some of one or more discharge cutoff voltages based on the battery cycle.

[0125] According to one embodiment, the electronic device can update at least some of one or more reference currents of a discharge profile based on the battery cycle. For example, the electronic device can increase at least some of one or more reference currents based on the battery cycle.

[0126] FIG. 6 is a flowchart of a method for updating a discharge profile according to one embodiment.

[0127] According to one embodiment, the following operations 610 and 620 may be performed by an electronic device (e.g., the electronic device (101) of FIG. 1). The electronic device may include at least some of the components of the electronic device (101) described in FIG. 1 and FIG. 2. For example, the electronic device may include at least one processor (e.g., the processor (120) of FIG. 1) including a processing circuit. The electronic device may include a memory (e.g., the memory (130) of FIG. 1) including one or more storage media for storing instructions. The electronic device may include a power management module (e.g., the power management module (188) of FIG. 1 or the control circuit (230) of FIG. 2) and / or a power circuit (e.g., the power circuit (210) of FIG. 2).

[0128] According to one embodiment, the processor (120) of FIG. 1 may include the control circuit (230) of FIG. 2. For example, the control circuit (230) may be implemented separately from or as part of the main processor (121) of the electronic device.

[0129] As described with reference to FIG. 2, a control circuit (e.g., control circuit (230) of FIG. 2) can perform overall control of a power circuit (e.g., power circuit (210) of FIG. 2). The control circuit can check charge state information related to the charging of a battery (e.g., battery (189) of FIG. 1 and 2). The control circuit can check signals (voltage or current) at the input or output terminals of components of the power circuit (e.g., conductive pattern (219), matching circuit (211), or transmitting / receiving circuit (213) of FIG. 2). The control circuit can determine the state of the battery based on at least some of the checked charge state information. The control circuit can control the charging or discharging of the battery based on at least some of the checked charge state information. The control circuit may be implemented, for example, as a logic circuit, a PMIC, or at least part of an application processor. In the following various embodiments, an operation performed by an ‘electronic device’ or a ‘processor of an electronic device’ may be understood as an operation performed by a ‘control circuit’ that controls a power circuit and / or a circuit related to a battery (e.g., a battery protection circuit included in the battery (189) of FIGS. 1 and 2).

[0130] As described with reference to FIG. 3, an electronic device can obtain state data of a battery (e.g., battery (189) of FIG. 1). The state data of the battery may include information on the battery's usage status (e.g., battery capacity, number of charge / discharge cycles, cycles, voltage, or temperature) and / or information related to charging (e.g., charge / discharge voltage / current, battery life, overvoltage, undervoltage, overcurrent, overcharge, overdischarge, overheating, short circuit, conductivity pattern of a power circuit (e.g., power circuit (210) of FIG. 2), a matching circuit, or a signal (voltage or current) at the input or output terminal of a transmitting / receiving circuit).

[0131] For example, the processor of the electronic device may receive at least some information regarding the battery's usage status (e.g., temperature) and charging from a battery protection circuit (e.g., a battery protection circuit included in the battery (189) of FIGS. 1 and 2). The processor of the electronic device may receive at least some information regarding the battery's usage status and charging from a corresponding sensor (e.g., a temperature sensor) among a fuel gauge IC, a power circuit, or a sensor module (e.g., a sensor module (176) of FIG. 1). The processor of the electronic device may obtain at least some information regarding the battery's usage status and charging.

[0132] The electronic device may store (or maintain) a discharge profile comprising one or more discharge cutoff voltages and a reference current corresponding to each of the one or more discharge cutoff voltages. The reference current may represent a current (or current value) referenced to prevent the power from being turned off even when the battery's remaining capacity is sufficient when the battery voltage reaches any discharge cutoff voltage.

[0133] An electronic device can update its discharge profile based on the temperature of the device's battery. As the battery temperature decreases, for example, the electrochemical reaction rate of the battery slows down and conductivity decreases, which may result in a relatively lower voltage during discharge.

[0134] In operation 610, the electronic device can determine whether the temperature of the electronic device's battery satisfies a second defined criterion. The second defined criterion may include a condition in which the battery temperature is in a low-temperature state that is lower than room temperature to a certain degree. For example, the second defined criterion may include a condition in which the battery temperature is below (or lower than) a threshold.

[0135] In operation 620, the electronic device may update the discharge profile by applying a second weight to at least some of the discharge cutoff voltages of the discharge profile based on the fact that the temperature of the battery of the electronic device satisfies a second defined criterion. For example, the electronic device may update the discharge profile by applying a second weight to at least some of the discharge cutoff voltages of the discharge profile when the temperature of the battery is below (or lower than) a threshold (e.g., 0°).

[0136] According to one embodiment, the second weight may be a value less than 1 (or 100%). In a state where the battery temperature satisfies a second defined criterion, i.e., when the battery is at a low temperature, the battery voltage may become excessively low and fail to reflect the actual remaining capacity. The electronic device may turn off the power of the electronic device at a relatively low voltage according to the updated discharge cutoff voltage by multiplying the discharge cutoff voltage of the existing discharge profile by a second weight less than 1.

[0137] According to one embodiment, the second defined criterion may include a plurality of conditions regarding the temperature of the battery. For example, the second defined criterion may include a condition in which the battery temperature is less than a first threshold (e.g., 10°) (or greater than or greater than a second threshold (e.g., 0°) and less than or less than the first threshold) and a condition in which the battery temperature is less than a second threshold (e.g., 0°). When the battery temperature is less than the first threshold, the electronic device may multiply at least some of one or more discharge cutoff voltages of the discharge profile by a first temperature weight (e.g., 98%). When the battery temperature is less than the second threshold, the electronic device may multiply at least some of one or more discharge cutoff voltages of the discharge profile by a second temperature weight (e.g., 96.5%). When the battery temperature satisfies the aforementioned conditions, the electronic device may update the discharge profile by multiplying the corresponding temperature weight by at least some of one or more discharge cutoff voltages of the discharge profile. The number of conditions, thresholds, and / or weights are exemplary and are not limited to the present disclosure.

[0138] According to one embodiment, the electronic device can update at least some of one or more discharge cutoff voltages of a discharge profile based on the temperature of the battery. For example, the electronic device can increase at least some of one or more discharge cutoff voltages based on the temperature of the battery.

[0139] According to one embodiment, the electronic device can update at least some of one or more reference currents of the discharge profile based on the temperature of the battery. For example, the electronic device can increase at least some of one or more reference currents based on the temperature of the battery.
