Weird. How were you able to fix it Poly?
Apart from this bug, everything seems to be stable over here.
I am not able to fix it
Charge your phone to 100% and let it sit for a bit.
I already charged it like 4times to 100% but the battery only has enough fuel to work for 4hours of wifi usage! (which is another problem, very fast battery drain since ios7)
Random restarts and excessive battery drain. I hope it's only an OS fix.
Yeah i hope it's only a software issue.
But with iOS6 and iOS7 betas my battery life was "ok"...i always had 7-9hours of usage with iOS6 and 7beta.
Try a "reset all settings". All your data and info and accounts stay but wifi, accessibility, notification center, location services, etc are reset.
I swear by it. Whenever I have something strange it clears it right up especially battery issues.
For the guage, if you restart the device, it resets that time until you fully charge.
Also a springboard crash will cause it to reset. Check Settings->General->About->Diagnostics->and see if you have a crash since your last full charge. Reset all settings can help with springboard crashes also.
I'm running iOS 7 on an iPad Mini. Ever since the upgrade, the battery usage stats inside" settings > general > usage" stopped working. (Screenshot attached).
Is anyone else experiencing this?

If you charge it to 100%, then unplug it, then restart your phone later, you should have no stats (again, like your screen shot).
why would it not continue to show after a restart?
The battery usage stats only measure the usage time from a full 100% charge on a single session (i.e. don't restart your phone).
If you charge it completely full to 100%, then unplug it, you will be able to see your stats until you plug it in again or restart it.
If you charge it to 98%, then unplug it, you should have no stats (like your screen shot).
If you charge it to 100%, then unplug it, then restart your phone later, you should have no stats (again, like your screen shot).
Hope that makes sense.
