Battery percentage Drain

Hey Guys,

I have been using my iPhone 13 for 9 months now. The battery health of my iPhone 13 is dropping more faster I think. Now it's reading 90% battery Health. Should I be concerned ?

iPhone 13, iOS 16

90% after 9 months is in an acceptable range, but a little low. iPhones generally lose about 1% a month, unless you are a very heavy user. Are you following the best practice for charging?


Once the capacity drops below 80%, or if there is a message in Battery Health that the battery is not meeting peak performance expectations, it’s time to change the battery→iPhone Battery Replacement - Official Apple Support. If this occurs within the 1 year warranty or the 2+ year AppleCare+ coverage there will be no charge for replacement.


The absolute best way to get maximum use on a charge, as well as slow the decline of battery capacity long term is to enable Optimized Battery Charging (Settings/Battery/Battery Health) and charge the device overnight, every night. The battery will fast charge to 80%, then pause. During the nighttime pause the phone will use mains power instead of battery power, allowing the battery to “rest”, and thus reducing the need to charge the battery quite as often. The phone will resume charging to reach 100% when you are ready to use your phone; it will “learn” your usage pattern. If you enable iCloud Backup (Settings/[your name]/iCloud - iCloud Backup) the phone will back up overnight also, assuring that you can never lose more than the current day’s updates.
