Last night before I went to sleep my iPhone X had around 98% charge. I set an alarm on it, and cleared every app from running in the background and turned of low power mode. Today morning when I went to turn the Alarm off, I had realized I was at 66%. How did my battery drain so quickly (I slept 6 hours)? I had a Instagram and Snapchat notification on the screen, after turning off the Alarm. Is it possible after one of those notifications popped up, the screen didn't turn back off? I checked my battery settings, as it was't showing any major usage, so I rebooted my phone and nothing changed. Anyone else experience this?
