Battery Calibration

[Aishwarya91]

Hey guys, do you know anything about battery calibration in Samsung smartphones?

Battery Calibration Code *#0228#

[Ashwin98]

It will be used to reset the battery's fuel gauge thereby resetting we can recalibrate our battery.

Symptoms or problems before battery recalibrate:
Phone getting switched off when it's 5-15% .
Drastic battery drain.
Battery percentage increase or decrease while connecting or disconnecting charger.

I think I've explained correctly upto my knowledge.

Recently I recalibrated my battery since one of the Hex installers update messed up my battery life. it's only recommended when you see a sudden drop in the battery like from 20 % to 15 % or 90 % to 75% like that. Even though I didn't have such a serious draining issue I went forward and recalibrated the battery.


>you have to completely drain the battery ( turn of automatically) try to restart again until it won't turn on.

>plug into the charger and charger fully( for m30s it takes around 3 hours )

>unplug your charger and you can see 100 % on the screen and enter the code you mentioned above and hit 🆗

I will leave a youtube video for more info
