Battery Drain Info:

The iPhone battery will drain, unless it is plugged in and charging. With lots installed, the charge would be slower. As for how fast it would drain the battery, that would depend on the Battery Health and the volume (sound) you use.

Did you recently do the iOS 17.6.1 update?

See https://osxdaily.com/2023/09/20/ios-17-battery-life-draining-iphone-fix/

Mine dropped from 80% to 21% over a few hours even with the charging cable plugged in. By the next day it was mostly normal. Some folks reported several days of excessive battery drain before it sorted itself out.
