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?
Got a tip for us?

also why aren't you just plugging in overnight? I don't know anyone without a bedside dock or cable.
I heard its bad for the battery. Yeah I know you can't "over-charge" a phone. Like you won't see such difference in one/two years, but if your someone who holds on to the phone for many years (like me), apparently charging over night decreases the battery capacity more like in 3-4 years. Not sure if its true tho.
For the purposes of what's described in the OP seems like there's no bad effect from that and is basically something that helps troubleshoot in the sense that the battery drain can't really be attributed to some app doing something in the background or something like that.
well i don't know how it works, but what if one or more of the apps he killed had background refresh turned on? I could see constant polling becoming a battery drain.
Background app refresh only works with apps that haven't been closed from the app switcher.
