    I've been having some pretty poor Battery performance as well. I had my phone sitting on my desk for about an hour and a half and without touching it the battery drops from 100% down to 95%. I don't know if there's something running in the background that's causing the battery just keep draining, but this is pathetic.

     

    I even just turned off LTE to see whether or not that would make a difference at all, I don't know if my phone is jumping from 3G to LTE causing any of these problems but I'll soon find out.

     

    But anyways, I made an appointment with an Apple genius for tomorrow so hopefully I can get a replacement, that's if they even have any in the back to give me. So far I'm very disappointed in the battery performance.

    I had the same problem on my 3GS and on my iPad, as soon as I upgraded to ios 6. I was so frustrated I Googled 'downgrading to 5.1.1' and found some instructions. I followed these but unfortunately, the phone restored with io6 again. However it completely cured the short battery life problem. I have done the same on the iPad, with the same results.

     

    I had originally upgraded through iTunes and so had a very recent backup. This is important if you are going to try this.

    So what were the steps that you followed to reinstall iOS 6? The only thing that I've tried but have not been successful with so far is erasing everything on the phone manually by going into the settings on the phone. If there's a way that I can re-download and reinstall iOS 6 completely and not just an erase, I would love to try that.

    These were the instructions. Although it refers to ios6 Beta, it applies to the release version.

     

    If you went ahead and installed iOS 6 beta and determined the buggy nature of the first developer release isn’t for you, it’s time to downgrade. Most developers should know how to do this already, but if not this process is easy and you’ll be back to running iOS 5.1.1 in no time at all.

    Downgrading is identical on an iPhone, iPad, or iPod touch.

    1. Turn the device off, connect it to the computer via USB, and launch iTunes
    2. Place the iOS device into DFU mode: with the device off, hold down the Power and Home buttons together for 10 seconds then release the power button, continue holding Home button until iTunes notifies you of a device in recovery mode being detected. The devices screen should stay black as if turned off.
    3. Restore within iTunes through either method a or b:
      • a: Restore from the iOS 5.1.1 backup you made prior to installing iOS 6 beta
      • b: Restore to iOS 5.1.1 IPSW by Option-Clicking the “Restore” button, and then restore from iCloud backup when finished
    4. Let iTunes restore back to iOS 5.1.1, the device will reboot when finished

    Let me know if you have issues.

    Since LTE isn't available in my area, I turned it off and I've noticed a huge difference in battery life. Much, much better.

    Thats awesome, but what if I just want to try reinstalling iOS 6 rather than for any version of iOS 5? Keep in mind again I'm doing this on an iPhone 5 which by default had iOS 6, but not the beta version.

    Yeah I'm in the process of trying to see how turning off LTE works. The signal in my area isn't terribly good and even on 3G it fluctuates between one and three bars and I'm sure I've seen it trying to switch to LTE but not staying on for very long, reverting back to 3G.

    These steps will restore your phone to the latest version of ios 6. The instructions were put out when 5.1.1 was the latest signed release. However that's now been replaced with ios 6 and so you will not get 5.1.1.

     

    You can either continue to restore from a backup afterwards, through iTunes or just stop with your 'factory' fresh iphone

    Okay awesome thanks, I'm going to try it and see what happens. I don't think I'm going to try restoring from a backup, however.

    Hi all, new iphone 5 64gb on O2(UK).

    Phone has been on standby since 11am GMT, now showing 94%. So around 9hours off charge.

    I dont disable anything on my iphones ever, im pretty happy with this drain if im honest.

    If i can help by anwsering any questions about my particular config or setup i would be happy to.

     

    Kind regards

    To me, your battery drain for a duration of 9 hours is completely acceptable. If I had mine off charge for that long in its current state, I would imagine I'd be at roughly 60 or 70%, and of course that would be with zero usage.

    To me it sounds like possibly an email account that is still trying to sync, try setting any accounts to show only 50 messages and 1 days worth.

     

    If that stabilises the drain a bit we can fine tune from there.

    My iphone 5 64gb has the same problem. I took it off charge at 1 when it was at 100% and by 2:30 it was 73% with no use. I hope I can get this fixed or replaced because it is very frustrating.

    Is it possible that the issue is with my phone constantly trying to switch between 3G and LTE? Like I stated above, the signal isn't very good in my house but with my iPhone 4 I've never had this problem, Of course before did not have LTE so that might be why.

    I was wondering about this too! Didn't they say the iPhone 5 had longer battery life or something? I dropped 50% in 3 hours just using 4g, with LTE on it dies even faster. I've begun missing my iPhone 4
