iPhone goes from 100% health to 50% health overnight while in sleep mode

[Tymbo]

From about 2am til 10am, I did not use my phone at all. It was charged to 100% beforehand and I did surf a little before going to bed at 2am. I did not plug it back in, and went to bed. When I woke up, the charge level was 50%!

Sure, I could disable bluetooth and other battery saving tips, but keep in mind the phone was in sleep mode. If Sleep mode is on, shouldn’t that mean there’s virtually no activity going on? ie. No alerts, no LED flashes, no vibrations, no need to “read the room”.

My battery health percent is at 86%. I’ve read online that the time for replacement is when it reaches 78%.

Do you think I am prematurely complaining about my battery issue, or could there be a bigger fault here?

In the second screenshot, you can see the details of the 5am-6am block, where it says my screen is “on” for a full hour. It was only on by ‘iPhone’, but again, it was in slee mode and I was sleeping! It’s like this all night long. Is that normal?

You need to post pics of how much battery each app is using from that page. The ones you've posted don't have the necessary info for people to comment on

That’s the thing — I have posted the apps. “iPhone - Audio 100%” is the only app consuming battery. However, it is on silent, in sleep mode with the Lock Screen on (not lit up), so how is there even anything consuming battery? Attached is another screenshot of the “Apps area” this time with “Usage” showing instead of ”Activity” (bottom of 2nd screenshot of original post). You can see I. The lower graph that something is using up 100% of iPhone activity throughout every sleeping hour — this is all “iPhone - Audio 100%”.
