1. Situation 1: The mobile phone has virtual power
< br >
The mobile phone has a virtual power means that you turn on the full power state, but after you turn off the charger, you find that the power display is actually only about 80%.
< br >
The Android system generally determines the battery power according to the battery voltage, and the voltage has two recognition modes.
< br >
One is software recognition, that is, after you turn on the system, the battery displayed on the 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 >
Usually the software recognition is higher than the hardware recognition of the voltage, so it will appear that we turn on the display is full, after the shutdown connected to the charger, but found that in fact only 80% or even lower power, want to be full? It's going to take a long time!
< br >
In fact, we often do not fully charge the phone, wasting part of the battery capacity, and naturally feel that the power is falling fast!
< br >
solution
< br >
First check if your phone has a virtual charge: turn it on and fully charge it, then turn it off and connect it to the charger to see if it is fully charged. If there is virtual electricity, then shut down full and use again, see if it will lose power fast!
< br >
2, situation two: too many background programs, CPU power consumption increases
< br >
This platitudes of the problem we can not be careless, Android is not a good point, that is, after the program exits, it will automatically run in the background. And in the case of mobile phones generally have no problems, these background programs are often the biggest culprit of power consumption!
< br >
As well as the phone's own screen brightness, wifi, Gps, Bluetooth, etc., and other Settings, these seemingly inconspicuous small things are actually power consumers.
< br >
solution
< br >
Periodically clean up the background running of the mobile phone to solve the problem of unnecessary programs occupying the running memory and increasing CPU power consumption.
< br >
Turn down the screen brightness of the mobile phone, turn off wifi, Bluetooth, etc. when not in use, turn off the key sound, key vibration and other power consumption Settings
< br >
Think about whether you have installed the program recently, uninstall it first, and see whether the power consumption of the phone is restored to normal, many of the small programs that we have ignored are actually amazing!
< br >
3. Situation 3: Battery aging
< br >
Most of today's smart phones use lithium batteries, and the average life of lithium batteries is 2-3 years, after 400-500 charging and discharging, it will accelerate the aging rate and become more and more durable.
< br >
Our daily incorrect use of mobile phone batteries will easily cause battery aging and reduced battery life.
