Mine stays at 0 minutes after the phone being locked for several minutes... Does anyone else have this?

I read that the various timers (screen on/off time, app time, etc.) have been buggy as hell throughout the beta process and bug reports were essentially ignored by Apple the entire time. Don't know how accurate that is because I'm not a beta tester and I saw it on Reddit, but that's what I heard.

I don't understand the battery readings at all anymore. Not only is the screen off time practically nothing, I'm wondering, does it not tell you screen on time since the last full charge? It seems to me like it only says for the last 24 hours.

So I had my phone off the charger for the last 6 hours and now Screen On time shows “1h 42m” and Screen Off time shows “47m”. Bizarre.

Yeah it doesn't make sense. For eg. My iPad over the last 24 hours shows 15 minutes of Screen Off time.

Screen off time isn’t supposed to be a counter of the time the screen is off but rather the time the device is working with the screen off. With that said, I’m not convinced any of this is terribly accurate either.

Pretty sure the screen off time, just like screen on time, is related to usage--basically it's usage with the screen on and usage with screen off (something wrapping up in the background, etc.).

Ok yeah, I see the total Screen Off time lines up with the "background" times of the Apps listed below.

The good thing about this new battery statistics screen is that it helped me identify which App was chewing the battery overnight - the IOS11 Battery Stats page didn't break down the hours whilst I slept so I didn't know when the Apps that were working in the background over the last 24 hours were eating the battery.

It's also helped me clean up & arrange my App icons on my Home Screen - by knowing which are my most used Apps over the past say 10 days, I've sorted my Apps according to usage 'tiers', with tier 1 being on Home page, tier 2 on page 2 etc.

Ended up having the Home Page bottom row completely vacant. Nice & neat now...
