Hello World!

reset – Reset Android – Part 34

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.

As in all Android phones, if you need to perform a hard reset on your Sony Ericsson Xperia Mini, then you have two choices. The first one can be fulfilled from inside Android itself. The second way may be invoked if your Android OS is too sluggish or clogged to respond. Both methods will allow you to erase all your personal data and installed apps,  leaving your Sony Ericsson Xperia Mini in a factory default state -as if you had just bought it-.

Hard reset  Sony Ericsson Xperia Mini from the phone itself

Assuming that your Android OS is way too damaged or sluggish to respond to the above instructions, you can perform a hard reset from the phone itself. You need to start with your Sony Ericsson Xperia Mini in a powered off state. If your phone right now is freezed, and you cannot turn it off, then please remove its battery, wait for some seconds, and reinsert it, to effectively turn your phone off.

  1. Make sure your phone is powered off
  2. Press the Left and Right buttons beneath the display and hold them.
  3. Press and release the Power button.
  4. You will get on-screen instructions to hard reset your Sony Ericsson Xperia Mini

You have two ways of performing a hard reset on your Motorola Droid Razr (or Razr Maxx). The first wayis quite easy, as it is done from Android OS itself, so you only need to select the correct option from the phone’s settings menu and it’s done. The second way of performing a hard reset on your Motorola Droid Razr is a bit more complicated but bulletproof. It’s fulfilled by invoking the hard reset mechanism on a lower, basic level, pressing certain buttons while turning it on, in certain sequence. Both methods of hard reset will end up with your Motorola Droid Razr (or Razr Maxx) in a factory default state, just as if you just bought it. Consider before going any further that this includes deleting all your information, including contacts, messages, apps and games.

Motorola Droid Razr, the easy hard reset

Provided that your Droid is turning on and working just fine, then you need to follow these steps:

  1. Go to your android home screen and select the Apps icon usually located on the lower right portion of your phone’s screen.
  2. From your Apps panel,  select “Settings” icon
  3. Once the settings menu pops up,  chooese the “Privacy” option.
  4. On the “Privacy” screen, choose “Factory Data Reset”

 Your Motorola Droid Razr may ask you your phone’s Password, or to draw the unlock pattern as a confirmation, and then it will proceed to reset itself. Allow it a couple of minutes to fulfill the task.

Hard reset your Motorola Droid Razr, the bulletproof way

This may be the only hard reset method that you got if your phone is too slugish to respond or your Droid Razr Maxx just freezes up when loading Android. Please follow these steps:

  1. Start with your phone in power off state. If it is freezed up and won’t turn off, take off its battery, wait for some seconds and place it back.
  2. Press and hold the Volume UP and Volume DOWN buttons and then press the Power Button.
  3. A menu will pop up asking you to select the Boot mode.
  4. Release all the buttons
  5. Press the Volume DOWN to scroll down in the recovery menu and select RECOVERY option by pressing Volume UP over it.
  6. Simultaneously press Volume UP and Volume DOWN buttons
  7. Select Wipe Data / Factory Reset and press the POWER button (note:  Deleting all your data will take some time).
  8. Select Reboot System and press the POWER button to restart your Motorola Droid Razr.

As you can see, when using the internal recovery menues, your volume DOWN button will allow you to navigate through its options.  When finished you will end up with a clean, ready to use, Motorola Droid Razr / Droid Razr Maxx phone.
