How to calibrate an Android device battery with root access

Despite the fact that I'm not persuaded that clearing the batterystats.bin record has any significant impact on how the Android framework reports remaining battery charge, there are the individuals who swear by this technique.

So in light of a legitimate concern for decency, we've incorporated the procedure for you here (without a doubt diverse makers utilize the batterystats.bin petition for various things).

It's basically the same process as above, but with the added step of using a root-enabled app to make it more reliable. Readers have rightly pointed out in the comments that newer versions of this app ask for a disturbingly extensive list of device permissions. If this worries you, we recommend trying the above non-root method first, and only resort to a 3rd party app if the first method proves unhelpful.

Instruction:

• Discharge your phone fully until it turns itself off.
• Turn it on and let it turn off again.
• Plug your phone into a charger and, without turning it on, let it charge until the on-screen or LED indicator says 100 percent.
• Unplug your charger.
• Turn your phone on. It's likely that the battery indicator won't say 100 percent, so plug the charger back in (leave your phone on) and continue charging until it says 100 percent on the screen as well.
• Unplug your phone and restart it. If it doesn't say 100 percent, plug the charger back in until it says 100 percent on screen.
• You want to repeat this cycle until it says 100 percent (or as close as you think it's going to get) when you start it up without it being plugged in.
• Now, install the Battery Calibration app, and before you launch it, make sure your battery is at 100 percent again, then restart.
•  Immediately launch the app and recalibrate your battery.
• Once you've calibrated your battery, discharge it all the way down to 0 percent and let your phone turn off again.
• Fully charge the battery one more time without interruption while it's switched off, and the Android system's battery percentage will be reset.

That's it. Have you tried these methods? Do you know an alternate way to fix battery problems? Let us know in the comments.
