I have my iPhone 15 charging optimization set to 80% limit. Today, I take my iPhone off the charger and the battery level reads 86%. Does anybody know why this would occur, and what could be done to prevent this from happening again? Thanks in advance for your response.
iPhone 15 Plus
From the Apple article:
About 80% Limit with iPhone 15 models
With iPhone 15 models, you can choose between Optimized Battery Charging, 80% Limit, and None.
When you choose 80% Limit, your iPhone will charge up to about 80 percent and then stop charging. If the battery charge level gets down to 75 percent, charging will resume until your battery charge level reaches about 80 percent again.
With 80% Limit enabled, your iPhone will occasionally charge to 100 percent to maintain accurate battery state-of-charge estimates.
This implies that it is around 80% not necessarily exactly 80% so it may still be working as intended. You could report it to Apple if you think it is a bug and not functioning correctly though

I’m facing the same issue. Have purposely capped at 85% but it’s being overcharged. I use original cable and adaptor, plus OS is up to date- 18.2 version

Does it happen every time you charge the device or only occasionally?
so after updating to iOS 17.3.1 my iPhone 15 pro Max started to lose battery really fast 1% for 3 min where before I could past 7-10 min with 1% of browsing the web. I have many issues with notifications all my apps like Viber Instagram WhatsApp telegram don't show messages at all. I received the message from the sender but I have to open the app to see that actually I have received the message. the phone doesn't show anything on lock screen or on active screen. furthermore battery exceeds charging of the 80% limit, before the update I had absolutely zero issues since I got the phone and immediately after updating to 17.3.1 before like three days or something like that, I started having this issue with the battery limit it doesn't matter if I turn it off turn it on it still charges above 80%. if I restart the phone the notifications start to come but after an hour or two they are gone again. The phone heats up a bit more in the hand where hefore even after 15 20 min ot browsing web it was still coller to the touch, now it's significantly warmer. I do notbuse my phone for gaming or something, just talking, video/photo shooting, shopping online. Furthermore - when I was updating the phone I was at about 82% battery life, I did not use charger or anything like that during the update and after the phone restarted, the battery was showing 99%?!?!
