4S on iOS 8 does not show battery usage by App

Mine is doing the same thing on a 5s. Ive tried all the things I could think of besides another restore.

I have the same issue on iPhone 6 - reboot didn't help.

Same on my iPhone 6 Plus 128. I used a backup from my iPhone 5 to set it up. Perhaps there is something in that?

Same thing although 7 day usage shows but seems wrong.

I have the same problem too... I had an Iphone 5 and the battery usage was working well, then bought iphone 6, restore in itunes from my lattes iphone 5 backup and now battery usage is not showing the percentages by app anymore..... 😟 please fix this...

I'm having the same issue with my iPhone 6. Nothing shows up when I look in the Battery Usage tab. When I upgraded my iPhone 5 the day that iOS 8 came out, the Battery Usage tab had loads of info but the iPhone 6 has nothing.

I really hope that this bug gets squared away soon.

I see the same thing as well (no information on application battery usage). I've had the iPhone 6 for 3 days now and see this problem on that phone.

My iPhone 5 and iPad 2 upgraded to iOS 8 both show usage information correctly.

The iPhone 6 was set up by restoring from a backup of the iPhone 5 that is working correctly.

I Thought i was the only one. I updated my 5s and it worked fine. I changed to the 6, and nothing showed up for battery apps. I wiped and reinstalled everything, still no luck.

iOS 8 battery usage not showing.

I have the same problem. I had a 5 and had iOS 8 then got an iPhone 6 and now cannot view battery usage stats.

Me, too! I also restored from a backup.

The suggestion here from deelan worked for me....

iOS 8 battery usage not showing.

Drain battery to 0%

It's just started working again for me - not immediately following the update- but soon after.
