How to Reset Samsung Battery or Calibrate the Battery On Samsung Smartphones?

What is Battery Calibration? When should You Calibrate the Battery? And How to calibrate the battery on Samsung smartphones? We are going to answer all these questions along with others.

What is Battery Calibration?

The android operating system has developed a mechanism to keep track of your battery percentage and charge levels to tell the users when it is full or empty. Sometimes, it goes corrupt and starts displaying unrealistic data stats. For example, your phone turns off even when it has enough charging.

It is usual that aging affects all batteries to degrade over time. The android operating system does not take this degradation into account while displaying the battery status on the screen.

Battery calibrating means getting the correct battery statistics even if your phone is old or when it was new. It should reflect the actual battery levels once again.

In other words, this process does not improve the battery nor improve the battery life. It is used to show the actual battery stats on the phone screen.

When should You Calibrate the Battery?

You should calibrate your Samsung phone with Battery Reset Code in the following circumstances:

  • Your device shuts down too many times when there is enough charge left
  • The charging percentage stuck at the same point for many days
  • You have an old smartphone and you are suspicious about it shows inaccurate battery stats

How to calibrate the battery on Samsung smartphones?

Samsung Battery Reset Code *#0228# or *#8999*228# is also used to calibrate smartphones. Samsung phones come up with an option called “Quick Reset” which is used by many technicians all around the world to calibrate the mobiles that report inaccurate battery stats.

You can also use this Samsung Battery Reset Code *#0228# or *#8999*228# to calibrate the battery on a Samsung smartphone.
Here is how you can do that:

  • Use your smartphone, until the battery reaches 5%, and then do not connect it with a charger

  • Press ‘Quick Start” from the appearing menu and then press ‘OK.
  • Wait until your smartphone power on and check whether the battery percentage has gone down or not
  • Charge your device to 100% again.
  • Power off your device and then turn it on and then unplug the charger.
  • Repeat these steps 3 to 4 times
  • Plug the career in again and the battery at 100%, press the power button and turn on the phone again, and dial: *#9900#.
  • Scroll down and find “batterystats.bin reset” and tap it.
  • Exit the menu and restart your Samsung smartphone

Note: Remember that battery calibration is not recommended on regular basis. Even when it is dead and your phone won’t turn on, still it has enough reserved battery to avoid any system damage. You should use this option once every four months, otherwise, you are inviting big trouble.
