iPhone 15 Pro Max is charging above 80

[Ariel32]

I have my iPhone set to not charge above 80%. Yet today it did. I thought maybe after the last update the settings reset themselves, but no, everything is fine.
Any ideas?
Thank you

Every once and awhile the phone will charge to 100% to calibrate the battery regardless of the 80% max setting.. This quote is directly from Apple's support page:

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.

Thank you!
That makes sense.
