battery Calibration

Use your phone until the battery dies. Wait until the screen turns off completely.

Turn your phone back on. It will likely shut down again before it finishes booting, but the battery isn’t completely dead yet.

Repeat this process several more times. Power it on, let it keep trying to boot up, then let it die. Eventually, the phone won’t even try to boot up anymore — you won’t even see the boot logo or splash screen. At this point, you can stop powering the phone back on.

Without turning your phone on, plug it into a charger. Let it sit there plugged in and turned off for at least 6 hours. The goal here is to charge it to 100% capacity without turning the phone on.

Once you’re confident that your battery is fully charged, go ahead and turn your phone back on. Resume your normal usage and normal charging habits.
