Battery status not updating

[Astrohunter]

Hi,

Sometimes I have to restart my phone for it to update battery percentage on iPhone 13 Pro Max.
Anybody else with this problem?

Does this only happens right after you unplug from the charger?
It happens to my IP13PM as well.
The first % drop after unplug will take a very long time.
After that the drop should be normal.
It should be a iOS15 problem because I tested it on my IP11 on iOS15, also same issue.

Yes i think so.
