iPhone Battery Health Count and how it works?

Bro ,
How to control battery health count and how it’s operates.
I brought 15pro max phone this Jan now my battery cycle count was 90 .
This is normal .
Kindly advice .

Kindly refer this episode about Charging Optimization and you can maintain battery health over period of months bro.

Battery Cycle as per apple document is, one full charge cycle that the battery goes through. It doesnt mean from 0 to 100%. But over several charges we do each battery sell goes through its cycle completion. Chemical and hardware level changes are measured through software and displayed as Battery cycle count.

So it may be inaccurate sometimes. Use the phone as per your requirement and continue following the simple charging practice. That will help to maintain your iPhone Battery Health overall bro.
