“Monitoring battery drain on iPhone and Flashlight shows up as main app in the Usage section. This must be wrong. I’m sure I never used it and it couldn’t be on for 7 several hours as I would have definitely noticed it.”

We did not notice this glitch until know but have managed to find a couple of similar complaints on Reddit:

“Can anyone explain why my Flashlight is using so much battery while it’s turned off?” (iPhone 14 Pro Max)
