Battery percentage isn't correct.
Ever since upgrading to iOS7 I've been noticing an issue with the battery percentage.
For example: it goes from 47% to 41% in a heartbeat, but when I plug my phone into the chrager it goes right back to 46%.
I tried restoring my phone through DFU not putting any backup on: it happened again. Went from 66% to 60%, only to go back to 65% when I plugged it in.
Has anyone of you noticed a similar bug? Or is it just my phone?
iPhone 5, iOS 7
