There are usually the following reasons:
< br >
Mobile phone virtual battery
< br >
I believe many people have encountered this situation: the phone shows a full charge at the beginning, but after shutting down or leaving it empty for a night, it is found that the power directly becomes about 80%, or even less. This is the mobile phone virtual battery.
< br >
Mobile phone power generally has two modes, one is the software recognition, boot into the system, the battery displayed on the mobile phone; The other is hardware recognition, that is, the amount of electricity displayed by the phone after connecting the charger when the phone is not turned on.
< br >
Mobile phone heat poor, body heat
< br >
Mobile phone charging while playing mobile phone is a lot of people have done, in this process, the back of the phone will be more and more hot. Because the mobile phone is in a high running state, the CPU begins to run abnormally, coupled with many people like to bring mobile phone cases, resulting in more power consumption of mobile phones.
< br >
Signal strength affects power
< br >
Different network modes of mobile phones are also the key to affect power consumption, power consumption ranking: 4G> 3G> Two gigabits. The phone will automatically switch between 2G\/3G\/4G networks, resulting in increased power consumption and faster power consumption!
< br >
Too many background programs
< br >
Many people's mobile phones will open Bluetooth, WiFi automatic search, positioning system and other functions, these seemingly insignificant functions are actually very power consuming.
The sudden increase in power consumption of the mobile phone may be that the background program is opened too much, or the battery attenuation may be serious.
Can be called out task management, the background resident some of the program to eliminate, to see whether it is still a large power consumption.
Do not overcharge when charging to ensure the health of the battery.
