A couple weeks ago I noticed that my under my usage meter, my "usage", and "standby" times were the same, even if I left the ipad in standby mode all night. I've seen this issue before in previous IOS devices, and knew this was likely due to an app not closing properly. I did all the troubleshooting such as doing hard resets, deleting/reinstalling recent apps, a restore from backup, and finally resorted to doing a clean restore. This seemed to have fixed the issue, but as I began re-installing apps, and getting things back to normal, the issue re-appeared. Today I spent a few hours after doing another clean restore, and checking battery usage stats every time I made a setting change, app install, etc. I think I finally narrowed down the culprit, the Mail app, specifically my Gmail account. The second I setup my gmail account, the issue re-appeared. I deleted the gmail account from the ipad, it went away. Has anyone else seen this issue? I've done the normal searches of the forum, but haven't found anything specific to Gmail. Thanks.
