My mobile phone Samsung s5660, fully charged, will soon be gone.

How long did it take you to fill it out? The mobile phone shows full, but the battery is not necessarily full. You can charge it for a while before unplugging the data cable.

It usually takes 2 hours for a mobile phone to be fully charged (from the time when there is no electricity).

Generally speaking, in your case, the main problem is the battery. And it depends on how you play.

You can try to calibrate the battery. (The premise is that the mobile phone must be ROOT) Specific methods:

1, shut down, plug in the power supply and charge until it is full. (It is best to charge continuously overnight to ensure maximum power. Remember, don't turn on your mobile phone until it is fully charged. )

2. On the premise of unplugging the power supply, start the machine. 3. After entering the system, delete the file /data/system/batterystats.bin with a terminal, Root Explorer or other similar tools.

3. Unplug the power supply and use the mobile phone normally until it is automatically turned off. At this point, the battery is still charged. Wait a minute or two, and then turn it on again to drain the remaining battery. If you want to speed up this process, you can consume electricity in any way. )

At this time, the mobile phone has regained the current battery information.

4. At this time, it can be used normally when fully charged in the closed state.
