I've.been having battery life issues like quite a few others and I've tried all the "turn off settings" ideas out there. Basically my phone drained battery 2-3 times as fast as ios6. Plus the battery percentage would jump around really sporadically... Sometimes going down 5-10% at once without reason. I then tried doing a erase all content and settings. Again the results were still the same with poor battery life. I then decided to do a reinstall by forcing a new ios7 download through itunes. (Search the web for "DFU reinstall itunes") I also deleted my icloud backup so I had to start fresh over. Since I did this a couple days ago I've turned all my settings back on and I'm getting GREAT battery life!! I'm amazes that doing a reinstall of the ios fixes things. I'm more amazed how great my battery life seem after a week of painful experience... Even though I know it's the same as with ioS6. I even have all the location, background refresh, and other small battery savers tips turned back to non saving modes. (Previously drained my battery after 3.5 hours of use and 7 hours of standby, now I can get 2x that after the reinstall) to be honest I haven't gotten it to drain completely by days end yet since doing the reinstall... I even used gps for 69 mins yesterday in addition to normal use) So use or loose, but I think a reinstall is in order. There must be some bad downloads out there, or the over-the-air had some bugs. One thing it'd be good to hear from others if they've successfully done a restore after doing this, or if part of the solution is getting rid of the icloud backup as well. Cheers! PS - it sure be nice for Apple to give us some hints on fixing this... They've got to have a ton of people having issues.
