Problems solved by technology

[0004] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: Since the user needs to set the working mode of the mobile terminal by himself, it often happens that the user does not correctly select the corresponding working mode, thus failing to achieve the desired result. Some effects of expecting battery life, for example, the mobile terminal is always set to the power saving mode, in which the CPU frequency is reduced, and at this time, the user will experience a freeze phenomenon when playing games; another example, the power of the lithium battery It is already lower than the predetermined threshold, but the user still sets the mobile terminal to the normal mode, so that the lithium battery is quickly discharged and shuts down, and the life of the lithium battery is also greatly reduced due to high current discharge

Embodiment 1

[0054] Please refer to figure 1 , which shows a method flowchart of the battery management method provided in Embodiment 1 of the present invention. The battery management method can be used in a mobile terminal including a battery, and the mobile terminal can be a mobile phone, a tablet computer or a notebook, and the like. The battery management method may include:

[0055] Step 102, judging whether the battery power exceeds the first predetermined threshold, if yes, then proceed to step 104; if not, then proceed to step 106;

[0056] The mobile terminal may determine whether the current battery power exceeds a first predetermined threshold in real time or at predetermined time intervals. Assuming that the battery power is represented by a percentage, the first predetermined threshold may be 20%. If the mobile terminal judges that the current battery power exceeds 20%, then enter step 104; if the mobile terminal judges that the current battery power does not exceed 20%, th...

Embodiment 2

[0063] Please refer to figure 2 , which shows a method flowchart of the battery management method provided by Embodiment 2 of the present invention. The battery management method can be used in a mobile terminal including a battery, and the mobile terminal can be a mobile phone, a tablet computer or a notebook, and the like. The battery management method may include:

[0064] Step 202, judging whether the battery power exceeds the first predetermined threshold, if yes, then proceed to step 204; if not, then proceed to step 206;

[0065] The mobile terminal may determine whether the current battery power exceeds a first predetermined threshold in real time or at predetermined time intervals. Assuming that the battery power is represented by a percentage, the first predetermined threshold may be 30%. If the mobile terminal judges that the current battery power exceeds 30%, it proceeds to step 204; if the mobile terminal judges that the current battery power does not exceed 30...

Embodiment 3

[0082] Please refer to image 3 , which shows a structural block diagram of the battery management device provided by Embodiment 3 of the present invention. The battery management device can be used in a mobile terminal including a battery, and the mobile terminal can be a mobile phone, a tablet computer or a notebook, and the like. The battery management device may include a battery judging module 320 and a mode setting module 340 .

[0083] The battery judging module 320 is used for judging whether the battery power exceeds a first predetermined threshold.

[0084] The mode setting module 340 is used for setting the working mode of the mobile terminal as normal mode if the battery power exceeds the first predetermined threshold.

[0085] The mode setting module 340 is also used to set the working mode of the mobile terminal as the power saving mode if the battery power does not exceed the first predetermined threshold, and the power saving mode may include any one or a com...

Abstract

The invention discloses a battery management method and device, which belong to the field of batteries. The battery management method includes: judging whether an electric quantity of the battery exceeds a first preset threshold value; if so, setting a work mode of a mobile terminal into a normal mode; and if not so, setting the work mode of the mobile terminal into a power-saving mode. The power saving mode includes any one or a combination of the following modes: forbidding use of some hardwares in the mobile terminal; forbidding use of some application programs in the mobile terminal and operation of some hardwares with degraded performance in the mobile terminal. Through automatic switch of the work mode of the mobile terminal according to whether the electric quantity of the battery exceeds the preset threshold value, the battery management method and device enable an endurance time of the mobile terminal to be prolonged and a charging and discharging rule of the lithium battery to be met so that an effect that a service life of the battery is prolonged is achieved.

Description

technical field [0001] The invention relates to the battery field, in particular to a battery management method and device. Background technique [0002] Mobile terminals such as mobile phones and tablet computers are the most widely used electronic devices in people's daily life. These mobile terminals usually use lithium batteries to provide power. Lithium battery, also known as lithium ion polymer battery, is a rechargeable battery that can be recharged repeatedly. It has higher power density, lighter weight and longer life than nickel batteries. [0003] In order to make the mobile terminal use time or battery life longer, an existing battery management method is: provide several working modes through the application program in the mobile terminal, such as power saving mode and normal mode; Select the working mode of the mobile terminal, such as selecting the power saving mode when the battery power is low, and selecting the normal mode when the battery power is high,...
