iOS Battery Drain
I’m just going to leave this here. I used the stopwatch during a workout.
It was on for about 8 minutes total, and stopped about 5 or 6 times. I’m not sure whether I remembered to stop it or whether the stopwatch kept running in the background.
At any rate, this seems an inordinately large amount of battery usage for a stopwatch. Whoever wrote a smartphone clock app that can use 41% of the battery should be ashamed of themselves.
Update from 2 May 2019: The screen was on for 6m, with no app usage and the Home & Lock Screen ate 91% of the battery. Thanks!
