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? :/

Thank you for reading and hopefully answering soon. :)

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.

Is it supposed to run even when on battery only when not at home? It
would had been nice if it happened when connected to a power charger at
home. :(

It happens regardless. And this has been standard practice for all
iPhones since the beginning, Ant. Your memory is really short. In the
future, plan ahead before installing updates or deal with the decrease
in performance until things return to normal.

It's normally not an issue and runs in the background. Occasionally it
drains more than normal for whatever reason. You seem to have hit one
of those occasions.

Actually, you also mentioned weak cellular signal which is very
effective at draining battery power.

Absolutely. When the cellular (or WiFi) signal is low, the device boosts
the radio power which naturally drains the battery faster. Combine that
with the normal post-installation indexing and cache rebuilds, and you
have a recipe for abnormally-high battery drain.

I wished there was a way to tell iOS not to the indexes and rebuilds. I
know using airplane mode for disabling cellular would work, but it was
in the purse so...

Not really, because you definitely want all of the benefits it provides.
It's been a normal part of system updates for decades. Refrain from
updating when you want peak performance. Simple.

I know using airplane mode for disabling cellular would work, but it
was in the purse so...

So, you couldn't take it out and turn cellular off? Not sure I follow
your logic.
