Fast battery drain since updating ios7 for iPhone 5

I updated to ios7 yesterday for my iphone 5. Since then then battery life has been cut in half. My phone normally last me through the day, approximatley 16 hrs. Since I have up dated to ios 7 my phone barely last 8 hrs. I disabled Apps Update, bluetooth, back ground refresh, and some location services. that di not help.

I've been reading around the web that I should do a fresh install. Would that help? Any advice would be appricated.

Yes...this sounds like a bad install

Update. I did a clean install as a new phone and so far I think that my battery life has improved. To soon to tell though. Sadly my Calendar events and SMS are gone. I created back up folders for my music and photos when i had my 4s with the same problem. I thought all the rest of my important information was back up in iCloud but that was not the case. I still have my contacts and notes in cloud but nothing else. Apple seriously needs to get these updates right. Its so time consuming restoring your phone manually.

Anyone know of a good software extraction so I can retrieve my Calendar events and sms?

iCloud does not require a computer or iTunes. It is not accessible at all aside from restoring your phone.

You will lose only the items you do not purchase from iTunes.


Settings > iCloud (Make sure you are signed in) > Storage & Backup > Turn on iCloud Backup > Backup Now


After the backup finishes Restore iOS Software

After the restore finishes Chose Restore from iCloud backup

UPDATE. It appears that a clean install with back up and a clean install as a new phone does NOT help the battery drain problem. Every minute that goes by when the phone is in use the battery drains. Also the back of my phone gets very warm. I guess my next step is to take it into Apple and see what they have to say about this issue.

Axeman, my question about iCloud even seeing my phone? Any clues? I use Find My Iphone app ON the phone and it doesn't even see it...would backing up even work? And my other option I guess is to download iTunes onto the old clunky desktop running Windows 7 (I think) and backup my phone to it. Then reset my phone, download the new OS and then run the synch to put my music and apps back. does that sound right?

Are you saying you can't see your phone on iCloud.com? Find My iPhone iOS app does not turn on Find My iPhone on iCloud. You have to turn that on in iCloud settings: Settings > iCloud > Find My iPhone - On


Backing up to iTunes is no different than backing up to iCloud. If you were to sync your phone to iTunes on any other computer besides the one you sync with, it will wipe your phone. You can not backup to iTunes until after first sync so that won't help. The only way to save your non-iTunes music is to use third party software such as TouchCopy to move it back to your computer. Then add it to iTunes on that computer and sync.

Find my iPhone is on and the computer i'm on right now doesn't see my phone through icloud.com, nor does the actual app on the phone. Laptop was the only computer i used before to synch with. I suppose I can always rip the original CD's onto the desktop. Seems like such a huge hassle all the way around just to fix a couple issues.
