I was thinking, to maintain a good battery health, to charge it to 80%. I was thinking to get it to 80 before going to bed, to 80 before i leave for school and if the battery lasts, redo the whole thing next day. Would it be harmful for my battery?
iPhone 14 Pro, iOS 16
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.

You should be fine, I’ve always heard it’s not good to keep it charging after 100 percent, but iPhones have an anti aging feature for batteries, regardless, all batteries still degrade slowly over time, but multiple times a day charging shouldn’t hurt.

You can hear all sorts of things, but the iPhone will not charge after 100%. The "charger" is in the phone and it is impossible for the phone to charge more than 100%.
Is it harmful for my iphone battery to charge it multiple times a day
