Hello,
 
Weird/Odd. Hot iPhone 13's iOS v17.6 (updated from iOS v17.5.1
yesterday) battery power percentage dived from recharged 88% to 23% from
6 PM to 9:30 PM while out to eat dinner in a crowded restaurant and
commute to there and back home. Battery statistics said it was hot to
recharge at 88% max. Usage shows "Find My" and weak cellular using half
in the background for the first hour, but after that was just "Find My".
Battery health shows 89% which is normal for this iPhone from 2/1/2022.
What's going on? Is this a new bug or something? :/

Higher than normal battery drain is expected with a new version of ios as
the caches and indexes get refreshed.

Give it a day or so to settle down.
