by

You may find your MW0821 tablet in need of a hard reset. This will revert the AOC Breeze MW0821 into factory default mode and thus you will loose any data, apps, games or configuration you may have stored inside it. This might prove useful if you want to sell your AOC tablet, or even get it back into functioning state if your MW0821 is working too slow or erratic to be useful, maybe because one or more apps you previously installed left it unstable.

 The easy way to hard reset Android on your Aoc Breeze MW0821 is by using the provided mechanism inside Android itself in order to revert it into a factory default state. You can search for the “Clear al settings” or “Factory default reset” options starting from your MW0821 home screen, invoking the SETTINGS menu, and choosing the PRIVACY submenu.

Here you will learn how to reset your Android battery algorithm.  This task is fulfilled by clearing up the  statistical information used by the charge / discharge algorithm inside your Android device to show you the nice battery stats icon and also to determine when your battery is in critical condition and your Android device needs to shutdown.

If your Android battery data is corrupted (its charging / discharging times and voltages are badly sampled) then your visual battery indicator and battery usage behavior on your Android device will act based on it, and thus you may end with a lower battery life, as your Android may either determine that a full charge (or discharge!)  is achieved “at any moment”.

If your suspicions are high on such behavior then it is time to perform a  reset of Android Battery data.  Be warned that this method will not fix the actual juice in an old or bad battery:  It will only reset the statistical data that Android got on it’s usage.

Performing a Reset of your Android battery data

Android battery data is saved on a file inside your Android device. In order to successfully reset the statistical Android battery data, you will need to simply erase such file.  This file location is  /data/system/batterystats.bin and sadly enough you will need to have root access (or superuser access) to traverse such path. You will also need to have a Terminal App installed in your Android device from which we will type and issue the following commands into your operative system:

  1.  su
  2.  rm /data/system/batterystats.bin

First step is to type “su” and hit Enter to gain SuperUser permissions. If you don’t have your Android device rooted, then this first command will fail. On the other hand, if you got it rooted, then it will ask for confirmation on the superuser access request:  Confirm it.  Second step is the rm command (remove) which will delete or remove the file located at /data/system  named batterystats.bin, thus effectively resetting your Android battery data.
