Case 1: The mobile phone has virtual power
The meaning of virtual power in the mobile phone is that you display the full power state when you turn it on, but after you turn it off, you can connect to the charger and find that the power display is only about 80%.
The Android system generally determines the battery power based on the battery voltage. The voltage has two recognition modes.
One is software identification, that is, the amount of power displayed on the phone after you boot into the system; the other is hardware identification, that is, the amount of power displayed by the phone after the charger is connected when the phone is turned off.
Usually, the software identification is higher than the voltage recognized by the hardware. Therefore, when we turn on the power, The displayed battery power is full. When the charger is connected to the power supply, it is found that it is actually only 80% or lower.
In fact, we often do not fully charge the mobile phone, wasting part of the battery capacity, naturally it will feel that the power is falling fast!
First check if your phone has virtual power: fully charged when booting, then turn off the power and connect to the charger to see if it is fully charged. If there is virtual power, then turn it off and use it again to see if phone battery drain fast!
Case 2: too many background programs, CPU power consumption increases
The Android machine is not very good, it will automatically run in the background after the program exits.
There are also screen brightness, wifi, GPS, Bluetooth, etc. of the phone itself, as well as other settings.
1. Regularly clean the phone in the background to solve unnecessary programs.
2. The screen brightness of the mobile phone is turned down. When not in use, turn off the wifi, Bluetooth, etc., turn off the button sound, press the vibration and other power settings.
3. Think about whether you have installed the program recently, uninstall it first, and see if the power consumption of the mobile phone is back to normal. Many apps actually consume a lot of power!
Case 3: Battery aging
Most of today’s smartphones use lithium batteries, and the average lifespan of lithium batteries is 2-3 years. After 400-500 times of charging and discharging, it will accelerate the aging speed and become less durable.
If we use the mobile phone battery incorrectly every day, it will easily cause the battery to age and the battery life will decrease.
