wait a couple of days and let us know if it starts to suck again.

This is all I can muster with a fresh install. This screen shot was taken just after the phone booted back up after it died on me down at 1%.

On my iPad mini, battery life seems to be the same or slightly better.

Honestly, I never restore from backup because:

1. Apps can be reinstalled
2. Music can be re-synced
3. E-mails are stored on their respective servers (gmail, outlook, exchange)
4. Photos I usually will manually copy or put it on dropbox
5. Settings I don't mind reconfiguring.
6. Contacts are backed up iCloud and you don't need to restore to retrieve them.
7. I don't save text messages either.

I'd hate to lose my messages, though. Oh, and games saves that don't get synced to iCloud.

EDIT: and on a side note, my old iphone 4 is sitting on my desk. its at 3:30 hours of use, 8 days of standby at 45%. its not activated, but still....just shows how poor the iphone 5 is in comparison.

That's completely irrelevant and shows nothing.

That's completely irrelevant and shows nothing.

sure it does. it gives light to the theory that the iphone 5, when using wifi and cell network combined, are double teaming the battery pretty hard as opposed to an iphone 4 which is on wifi, but not cellular capable. its usage after 8 days is half that of a fully functional phone (3 hours, all background use). this shows that ios 7 may not be the issue on its own, but a combination of ios 7 and the iphone 5 specifically.

No, it means nothing. Any modern smartphone that's merely connected to wifi is going have better battery life than one that is connected to a data network as well. The two biggest drains on a cell phone are the screen and the mobile network. Your logic is bad.

Curious how many have done a reinstall of iOS 7 as new without installing from backup... any luck with better battery life?

If you updated OTA, you'll want to do a Settings, General, Reset All Settings.

Better today...

Maybe the fresh install did work. This last charge got me through a full day and that's all I am really looking for to begin with.

I will now stop checking my battery percentage and enjoy this awesome piece of technology!

Fresh DFU reinstall improved battery life on iPhone 4 @ iOS7 , but still is not as good as iOS6....

 

[vong]

Going to try this if my current DFU restore with a back-up does not improve my battery. 2 hours of usage is not going to cut it.

That's just it, I use to do a restore from new and a few days later it was back to normal. I just reinstall and restore from back up. My battery life is good and no hassle of setting it up (wifi pass codes, email pass codes, and other pass codes)

I think it's just a false myth ...

Sadly iOS 7 ruined my iPhone 's battery life (I can't reach 5 hrs usage time !!!), but I can't see a reason for reinstall all apps to improve it

----------

I have been debating this for the last few days and might give it a shot. The only thing that was keeping me back was app data, mainly in games that I have been playing for a while, but I don't want to sacrifice battery life for app data.

Here are my numbers for battery...just feel like my iPhone 5 was better then my 5s when it comes to battery.

I'm experiencing very similar results as yours ...
Pretty disappointed, I used to have at least 2 hrs more (maybe 3!) with iOS 6

What did you disable to get that result ? Background app refresh ? What else ?

 

[spades1412]

Not bad after setting up as new device.

 

[benoitgphoto]

I always been skeptical about those reinstalls but I decided to give it a go and I must say that it really improved the battery life!!

Clean install makes all the difference in the world. The first thing that I did with my 5s was to wipe it right out of the box. I get 8 hours of screen time everyday with about 20% left. All options on except bluetooth. If your not doing 7-8 hours screen time everyday then wipe it. Amazed that people on this forum don't understand that.

Same thing with my wife's iphone 5. After restoring and set as new device, we let it sit overnight on standby. The phone went from 100% to 16% in 6 hours without any usage. Thats not normal.

We are gonna stop by an apple store and see if they can replace it. We got this phone brand new as a replacement in June. I hope they will help us.

DFU installed iOS 7.0.2 some days ago, got this result with 3G and wifi always on, cellular data on for 3-4 hours, the rest on wifi.

Mine is hanging in there fairly well so far. My iPhone 5.

 

[Max(IT)]

This thread made me crazy ... 7 hrs ... 8 hrs ... I barely reach the 5 hrs threshold and I have disabled almost all the new things !!!

 

[sunking101]

Me too. All my settings are the same as I had on iOS6 and *all* new settings are toggled off with email on fetch etc but I'm getting a full 3 hours less usage even after a clean install.

iOS7 killed my three month old iPhone5.
