Battery is being used up too quickly iphone 5 ios 7

My wifes phone had the same issue.....no activity yet batter just keeps dying...we have tried the battery saving tips being released but it's still draining......was not like this before the update and she's had ip5 for a year

On Verizon? I am and had/have the same issue, read this: http://www.extremetech.com/computing/166884-iphone-5-battery-life-is-significant ly-reduced-by-ios-7

Turn your wifi off and see if that fixes it. I believe there's a wifi bug on the Verizon iPhone 5 in iOS 7.

We are on ATT...was fully charged during the update to 100% and died overnight while it was on standby

This happens to some phones after every upgrade or restore. Some app on the phone was active and was interrupted by the upgrade. When it came back up the app tried to resume and failed. You've got to find and kill that app. If you have an Exchange account that is the prime suspect. Go into Settings and turn off all of the switches (mail, contacts, calendar, notes, etc) for the Exchange account. Then reset the phone by holding HOME and SLEEP until an Apple logo appears. Once the phone comes back up turn the switches back on.

It can be other apps also. iOS 7 has provided a way to control background execution of apps. Go to Settings/General/Background App Refresh. This will list all of the apps that can run in background and use power. Start by turning them all off. If this fixes the problem turn on a few at a time until you find the perp.

thanks , I will try that tonight , if that doesn't work do you recommend a full restore?

I'd still try turning the wifi off and see if that fixes it. It totally did for me, as mine was't lasting through the day. I unplugged mine at 5:30am this morning, and with the same usage as yesterday, with wifi off, I'm at 76% battery (it's now 3:53pm). I tried killing all the apps, rebooting the phone, and even deleting and resetting up my email, only turning off wifi fixed it.I know it's not the phone itself, because I'm experiencing this on two iphone 5's.

Mine went down 15% but then I noticed in notifications it downloaded several updates during the night.

Yes, a full restore will usually fix it, but that's usually overkill. A full restore on my phone takes about 8 hours, but that's because I have 9,000 tracks, and I have "Convert higher bit rate songs" checked. Each track takes several seconds.

I did a full restore, didn't help.

Im also finding the same problem on my iPhone 5! you are not alone!

I did a hard reset and it seems to have fixed my problem as well.

I suggest reading the other messages above and below yours.

When you did the full restore did you restore your backup, or set up as a new phone? If you restored your backup it means that your backup is corrupt. Try Restore as New. If this does not fix the problem then either you have a hardware failure or the iOS 7 image that was installed is corrupt. Delete the IPSW file from your computer and restore again.

If the Restore as New resolves the problem before you add any apps or email accounts try restoring your backup using iTunes. Sometimes separating these two steps (Restore and Restore Backup) resolves it.

I'll bet this is the new Background App refresh taking its toll. I noticed that the battery seemed to be draining faster than normal on my iPhone 4 - I went to the background app refresh page - Settings -> General-> Background App Refresh and then just turned that off and voila - normal battery drain again.
