Battery indicator not refreshing
Hello, I have a very annoying issue.
For some reason, my battery indicator doesn't refresh and get stuck a the percentage the battery is at when booting. For example : if the real percentage of the battery is 71%, when booting, it will show 71%, forever. Even if I use wifi for hour or more !
If I power off my phone, take the battery off, press the ON button for a while, then put the battery back and start it again, the battery show a lower percentage (the real one). But then stay forever at this new value.
What is wrong ? I tried wiping everything, flashed 3 different roms, tried with 3 different batteries with no success...
