Hi everyone. I've been having an issue with the battery usage time on my Retina iPad Mini. I've even erased everything and set it up brand new, not from a back up, and it's still having the issue. The usage time for the battery isn't accurate. In the attached screenshot, it says standby is 2 days and 19 hours and usage time is 9 hours and 30 minutes. I've used the device for maybe 2 hours since the last charge. I'm running iOS version 7.0.6. I've brought the device to Apple and they told me nothing is wrong with the unit and it must be some sort of software issue that they aren't aware of. Has anyone else experience this issue and know how to fix it? Thanks.
