I charged my iPhone 15 to 80% last night and turned off the phone. After turning it on in the morning, it showed 83%. Why did this happen? Is it normal?
I purchased this device brand new three weeks ago. I only charged it to 100% on the first charge, and after that, I set an 80% limit for every charge. Also, every time I charged, I followed a 40% to 80% charging pattern. The iOS version is 17.2.1. Battery health is 100%.
iPhone 15, iOS 17
