When the Android system determines whether the battery is charged or not, it is based on the voltage of the battery.
In other words, the voltage of your battery will become smaller and smaller when you use it, until it reaches the lowest voltage for Android to shut down, and the phone will automatically shut down.
Here's something to note: The voltage recognition modes of our mobile are divided into two types:
1. Software recognition is the percentage of battery displayed on the system after you enter the system.
2. Hardware recognition When the data cable is plugged in and charged when it is not turned on, the percentage displayed when it is charged.
There are differences in these two recognition patterns. The voltage recognized by the software is higher than that of the hardware. That is, when you turn on the charge and see that the battery is at 100%, the battery is not fully charged.
When we turn on the battery, fully charge, unplug the data cable, then turn it off, and then plug in the data cable, you will find that the battery is about 80%, it can still be charged, and it will take a long time to charge to full charge. In other words, you waste part of the battery's capacity and don't use it, and it naturally loses power quickly.
The full and empty state of the battery is recorded in the system file batterystats.bin, and the file needs to be reset to solve the problem
1) Turn off the phone, plug it in and charge until it is fully charged. (It is best to charge continuously overnight to ensure maximum power.) Remember not to turn on your phone until it is fully charged. 2) Turn on the power without unplugging the power supply or data cable. 3) After entering the system, use Root Explorer or other similar tools to delete the /data/system/batterystats.bin file. 4) Unplug the power or data cable and use the phone normally until it turns off automatically. At this time, the battery still has extra power, wait one to two minutes and then turn it on again to use up the remaining power. (If you want to speed up this process, you can use any power-consuming method to exhaust the power) 5) At this time, the phone has re-obtained the current battery level information. At this time, fully charge it again in the shutdown state to start normal use.
Description: 1. /data/system/batterystats.bin This file is the system records various battery information including voltage, and the system will start counting battery usage information again after deleting this file. 2. When flashing ROM, the file /data/system/batterystats.bin will be deleted. Therefore, flashing the computer when the battery is not full will cause the system to start counting battery information again when the battery is not satisfied, which will affect the normal use time of the battery.
