Android tutorial: Remove battery information to increase standby time

Many friends feel that the battery is not durable after brushing the machine. It is a problem with the ROM. In fact, it is a big god. Just follow the following steps to solve the problem that the battery is not durable. The battery information of the Android system is saved in the /data/system/batterystats.bin file. When the machine is flashed, the DATA partition will be formatted. That is to say, the battery information will be cleared once for each brush, and the file will be rebuilt when the machine is restarted for the first time. . If the battery is not enough when the machine is flashed, the reconstructed battery information may not match the actual state of the battery, resulting in a problem that the standby time becomes shorter. The solution is as follows: 1. Shut down, plug in the power and charge until it is full. (It is best to charge for one night to ensure maximum power. Remember not to turn on the phone before it is fully charged.) 2. Turn on the power without pulling the power. 3. After entering the system, delete the /data/system/batterystats.bin file with the RE manager or other similar tools. 4. Unplug the power supply and use the mobile phone normally until it automatically shuts down. At this time, the battery still has some power. After waiting for one to two minutes, turn it on again and run out of remaining power. 5. At this time, the mobile phone has regained the current battery power information. At this point, you can start normal use when you are fully charged in the off state. Additional explanation: 1./data/system/batterystats.bin This file is the various battery information recorded by the system including the voltage. After deleting this file, the system will restart the statistics of the battery usage information. 2. Because it takes a little power to enter Recovery, if you delete the battery information file when the battery is not full, it will affect the reset effect. Recovery usually also has the function of clearing the battery information, but the process of restarting into Recovery itself uses a part of the power, so it is also recommended to follow this tutorial. 3. The file /data/system/batterystats.bin will be deleted when the ROM is scanned. Brushing the machine when the battery is not full will cause the system to restart counting battery information when the battery is not full, which will affect the normal battery life. Summary: The battery of the smart phone has always been a big problem. Compared with the endless expansion function, the battery is never enough. Although the above methods can solve some problems, but can not solve the fundamental problem, the problem of solving the battery really needs to be solved. Innovation in battery technology. If you feel that the battery is obviously not as good as before, or the battery information is obviously abnormal, you can try the above method, but don't expect too much.
