Battery Life by App... Not Working. Argh

[gavroche]

My battery life by app is not working. See screen shot. Says that it will be available after a few minutes usage... but as you can see in the screen shot it has over 7 hours usage and still nothing. I have since drained it until the phone died... fully charged it... rebooted.. and still nothing.
Any ideas of a fix?

Have you tried doing a hard reboot

Reboot has done no good.

There is a small thread here of people having similar problem:

Common theme would seem to be that each of us had restored a phone from a backup. The only person that seems to have gotten it working again had drained it to 0%.... myself and some others have done this to no avail. Reboots and Reinstalling from backup over again has not helped either. Frustrating.

I had this issue at one point. I also had the usage and standby numbers equal at one point. I also had "Hangouts" show that it used 100% of the battery at one point. Everything is working normally now. It was like one morning, it just worked.

Same problem here... I'll try to drain the battery to 0% when I have time and report

Update: Today it started showing battery usage by app. Nothing has changed in the last week with the phone or the operating system (no updates or anything)... so i really have no clue why it suddenly decided to start working. But now it is.
