Potential energy savings bug when capping loading to 80%?

[Pclaesen]

This morning I had my iPhone 15 Pro on energy saving mode. I capped the loading to 80% through the new iOs function.
To my surprise, the phone charged to 83% before I noticed. Anyone else noticed this?
I understand battery percentage is not 100%% correct, but capping at 80% shouldn't allow charging to 81% even imo.

this has come up multiple times on this forum. The documentation clearly states the phone will charge above 80% on occasion.

This. I guess Apple would be better off putting this “occasionally charging to 100 percent” notice in the Settings, right next to the toggle, to keep everybody zen.

Ok thanks both of you. Never read that docs page tbh.
