iPhone 5 short battery life?

Hello All,

Just went to my local Apple Store and the Genius I worked with said it was definitely unusual to be getting such low battery life even under more active-use conditions than I've been dealing with. They replaced it on the spot, currently syncing everything back to the phone and will update later tonight or tomorrow.

Well. Reset all settings. Didn't work. DFU restore didn't work.

Full charge overnight. 2hrs 56 minutes of use (little Internet or calling) 5hrs 36 minutes stand by. 28% left.

That's is ridiculous. Have a genius appointment. Hopefully they have an answer for me.

My battery keeps getting worse everyday. Only got about 2hrs 30 min use from it today (nothing intense) and i was down to 32%.

My wife's phone is about the same on battery, but she has a few other issues with hers too (touchscreen keyboard issues, sound issues, network connection issues, etc) she's not happy at all.

We have a genius apt on saturday (closest store is an hour and half away) so hopefully we'll get most of her issues worked out. I'm sure the battery issue will still be a problem even if we do get new phones. Need apple to push out an ios update more than likley to fix it.

PROBLEM SOLVED!!!!

I was having the same issues with deplorable iPhone 5 battery life. The solution was posted earlier in this thread and it fixed my issues. The solution deals with restoring the iPhone 5 on iOS 6 as a new phone but it really works. My battery life is now better than my pervious iPhone 4.

I had my battery checked at the Apple store by a Genius and it checked out as normal. Whilst talking over the problems (and the aforementioned solution I saw on here) we decided to give it a go. The solution unfortunately involved setting the iPhone up as a new phone. YOU CAN STILL BACK UP CONTACTS AND OTHER IMPORTANT DATA.

1. Go to settings > iCloud > choose which individual items you want backed up.

NOTE: I didn't back up any apps because I don't use any to save data for. If you do - and you might want to confirm this with a Genius - go to Settings > iCloud > Storage & Backup > Manage Storage > Your Phone Name > then toggle apps on and off (again, not sure if this was even available when I originally backed up my iPhone and I didn't want to save anything from apps. I wanted a fresh install to fix the battery problem.)

2. Restore the iPhone at the Apple Store (to guarantee against a corrupt version of iOS 6).

3. Set the iPhone up as new. DO NOT click any of the options on the Apple Store computer. Disconnect from computer.

4. Restore backed up items from iCloud. (Genius will help you if its confusing - he had to help me 😉 )

5. Boom. You will have to tweak a few settings again and whatnot and probably set up email accounts again but trust me, its worth it. My battery is no longer an issue. My iPhone went to work with me yesterday charged to 100% and I used it off and on through the day on LGE with Facebook, apps, texting, phone calls, etc. And when I got home I continued using it til I went to sleep at 5am. I woke up today with over 50% battery remaining.

I'm not as eloquent as other folks on here but I really hope this helps.

Am I the only one that thinks starting from scratch or turning off half the features on the phone is a dumb way to fix this issue

I don't think we should need to start from scratch. Isn't that the point of iCloud? Also the advertised 8 hours is with wifi or cell or LTE, so why TNR it off?

I'm don o 16%. 3hrs 20min.

Gonna go to apple tonight.

Full DFU restore didn't work at all. Battery burns faster now.

Try Settings > General > Reset > Reset All Settings.

If it works, it's a really quick fix. If it doesn't work, it doesn't take much time or add aggravation, either.

I did a restore, and it did not help. Down to 30% with 6 hours, 2.5 of that was with use the rest stand by. I am going to an apple store tomorrow for an exchange. I found this article, which talks about a reason poor battery performance: http://www.macrumors.com/2012/09/26/iphone-battery-life-greatly-impacted-by-cell ular-signal-strength/

Only reason resetting all settings works is because it turns everything off. If you go in and turn everything back on that you would normally use your battery starts draining super fast again

That trick didn't work or me. Neither did DFU restore.

2 hours, 3 minutes Usage

8 hours, 28 minutes Standby

49% battery left.

Not horrific like some but not good.

3 1/2 hours of use. Little wifi or calling. 11% remaining. Stand by 7 1/2 hours.

Can you elaborate on what you mean by "manually restored from the most recent backup"?

Hi,

It was a two part backup. When I received the phone I restored the backup from the iPhone 4. Afer that was restored, I backed up the phone again with the iPhone 5. Then I performed steps 1-3 and in step #4 restored from the most recent backup in iTunes.

So:

restore iphone 4 settings on iphone 5 w/ battery problems

backup iphone 5 settings in iTunes

perform steps #1-3

restore iphone 5 settings

reset all settings as shown in step #5.

I was loosing 1% every 2 minutes with all Apps off and phone in standby, no wifi or bluetooth.

After re-reading http://www.apple.com/batteries/iphone.html I made some adjustments, while comparing my old iPhone 4 settings which worked fine.

Charged phone up to 100% and switched quite a lot of notifications off, adjusted Mail settings and the one that I think has made the most difference was Facebook. You seem to actually have to go into the app itself to switch off all the notifications.

After an hour sitting on standyby the phone is still showing 100%. Hopefully that is it sorted.

If you set up your iPhone as new and then restore from iCloud, aren't you just inheriting the same problems associated with setting it up from a backup from the get-go?

Could someone explain?

For me it's not clear how you set up as new and then do a restore, without overwriting the "new" state. We all had a "new" phone with the iPhone 5, then those of us who restored from a back-up had battery drainage.
