Battery life on iPhone 5

I ran a test last night.

Charged iPhone 5&4 to 100%

Closed all apps, turned off BT and wifi

on the 5. Put in standby mode at 100%.

Did just opposite on the iPhone 4 (w/iOS5).

Launched 27 apps. Turned on BT and wifi.

Plus did 20min of web browsing, listened to a

45min podcast. Put iPhone 4

into standby mode at 97%.

7 hours later.

iPhone 5 dropped 22% in 7 hours.

iPhone 4 dropped 7% in same 7 hours.

Cupertino...we have a problem.

I wonder if that will work. I loaded my iphone5 from scratch, not from any back up from my previous iphones and still have this battery issue. But what some are saying that should help but it sure hasn't with mine

It will be interesting to read if this factory type reset works or not

so has this "factory reset" worked? a day or so after it was attempted

did mine as "new" phone, not from any back up and have same issue

Well for me it seemed that the "trot nixon" worked. Still running tests today, but as of now see a better battery life than yesterday around the same time.

I am having the same issue. I just recharged my iphone5 at 5:51pm Arizona time and will see how long it lasts. If not long, I am sending it back to Verizon Wireless and buying a different phone. I have never had this problem with other phones. This is the first time I have purchased an Apple phone and so far am dissapointed in the battery life.

Guys, i did some investigation on my current settings. I upgraded to the iPhone 5 from an iPhone 4. I did not set it up as a new device, I used my backed up 4's data and restored from iCloud.

After doing a lot of research and investigation and talking to Apple too i am a 100% sure that its a bug in the restore process. After restoring to iPhone 5 for some reason the apps + system process think that its an iPhone 4 with a single core A4 processor and et all. Whereas its an iPhone 5 with A6 processor et. al. The software and the OS aren't using the hardware as it is meant to be used due to the conflicts brought along with the restore thereby impacting the battery life.

We got 2 options:

1. Erase all contents and data then Restore your phone as a new iPhone and manually download apps

2. Wait for apple to release a fix.

P.S. definitely let your battery drain out fully once and give it a full charge after that (did work for me a little before i found the actual bug)

initially I had set mine new 5 up from my iPhone 4S backup...major battery issues. I then performed the DFU Restore process and completely re set up my iphone 5 as a new phone and unfortunately the issue is still there!! It seems it''s more of a general iOS 6 software issue and not a hardware or restore issue.

anyone else found similar problems even after doing a full restore as a new phone?

I have a Genius Appointment tomorrow afternoon so we'll see what they say... I doubt they'll replace at this point because the issue seems a lot more widespread for it to be a "few" bad phones.

Jeeze, today, thanks to the TROT NIXON method, I can't even get my battery to run down enough so to perform my tests! Thanks again TROT!

Well I may have to wait for the apple fix, as I set my iPhone5 up as new from out of the box, then synced my apps, contacts, tunes, pics from my iTunes on my MacBook Pro but still have the poor battery life.

I will try the hard reset tomorrow Thanks for all this, you all have been very helpful

Try disabling Safari sync in iCloud services. Let me know.

Thanks. I just did and will let you know in a couple of days if that worked.
