Timmy, do you have WiFi sync enabled? (not necessarily using it, just checked in iTunes).
I found this was more then doubling my usage at night while I was sleeping. I would wake up with the battery going from 100% down to 40% ... I turned off WiFi sync and its been fine since.
If you have the option checked, you might want to try disabling it and see if that helps.

I've been watching this thread as I too have experienced very poor battery life on my new iPhone 5. Compared to my 2-1/2 year old iPhone 4, the new 5 performed well below what the 4 was giving me.
I did perform a regular restore via iTunes (new phone set-up) and gave it a day of use. I would get about an hour or 2 of stand-by with the battery indicator staying at 100%. I thought: appears like the restore did it! It didn't. After using it the indicator would drop way too fast. This while just browsing, texting on Wi-Fi.
So this morning I performed a DFU restore. Let the battery charge up to 100% and have been using since I disconnected it from iTunes. I've spend the past 40 minutes modifying settings, tweaking apps and performing all my log-ins. 40 minutes of constant use has resulted in NO battery loss. Still sitting at 100%. Very similar to how my iPhone 4 performed.
Will run this charge cycle out today and fully charge over night. Will post any changes, but it appears the DFU restoration may well be the remedy.

I said the same thing! However at this point in the day now it's dropped faster, i've played some music made a few phone calls and done some text messaging and i'm down to 85% now phone i showing i've used it for over 2 hours today but in total i've calculated i've only used it for about 1 hour and 20 minutes. Not sure what's going on, only app on phone is facebook, twitter and pandora and not one of them is running, no email even setup right now. I made an appointment for friday for the genius bar just to be sure it's not the phone.

Thanks please let us now, I am going to try a DFU tonight when I get home.
Just called Apple and the rep basically laughed at me like I was nuts. Says this is the first she is hearing of any battery issues. Treated me like a 2 year old - telling me to close apps running in the background which is not the problem!

I have 1-hour and 15 minutes of use (and standby) on the phone now - this use included watching about 15 minutes of Rise of the Planet of the Apes (locally) and about 10 minutes of SiriusXM streaming. My indicator is at 93%.
Going to let it sleep for the next hour and see if I lose any of that 93%. If DFU remedied the problem, in one hour it should still be at 93% or 92%. If it's under 90, safe in assuming the issue persists.

No. After seeing that usage stat I wonder if ios 6 is not shutting down background apps (like it used to). I'm going to kill all apps before bed time tonight and see if there's a difference.
And FWIW I only have one mail account set to push and it's an Exchange account.

Same battery issue here. I'm not seeing a concensus yet. If I can fix it I want to. Otherwise I'll hit the Apple Store. Watching this thread to see how things go.

OK. As posted yesterday, doing the DFU restore (then loading everything through a backup restore--not setting up as new phone) and conditioning the battery really did help. However, throughout the afternoon it was worse than I had anticipated in the moring, losing about 10% per hour (better than my original 2-3% every 5 min, but still), so I went to the Apple Store and I swapped it out for a new one.
The guy ran diagnostics on my phone ad couldn't see anything wrong with the battery. BUT, he did notice the weird jump in usage time while the phone was idle that some of us were/are experiencing. He said the possibility was a faulty processor that was continuing to run, thus causing the battery to drain to quickly. He said he wasn't convinced that was it, because the phone would have also been running hot (note to all of you with this issue).
So my new phone--not any better on battery life at this point. He recommended I NOT restore from backup (confirming what so many of you are saying) and set up as a new phone. Yuck, but OK. I wanted to drain the battery, so I didn't want to plug in and sync at this point. I also wanted to monitor battery life, so I only downloaded the few apps I wanted for the evening, then went ahead with my normal light usage (a few texts, a few games, reading, checking email). Phone had about 80% out of the box at 7:00 last night. By 9:00 this morning, I was at 38%. Doesn't seem great. Back to square one...

I've had the exact opposite experience. My iPhone 5 battery life is very long, very pleased with is so far.

Could someone please tell me what the battery percentage should look like under normal circumstances with 3 hours 7minutes of usage and 14 hours 00 minutes of standby
Currently Being ModeratedSep 26, 2012 11:22 AM (in response to ebrown711)
1 hour use
6 hours stand by
71% battery left here.
The hour use was email, phone, and minimal internet.
not extremely bad but not good either. My 4 was better. Maybe its worth waiting things out and cycling the battery a few times?

After letting the iPhone sleep for an hour (with receiving several e-mail notifications and few messages notifications and taking an 8-minute phone call), the phone is now at 90%.
Uncertian if that is on-par or not. Will plan on grinding the battery down for the rest of today - and perform a full charge cycle tonight/tomorrow.
Currently Being ModeratedSep 26, 2012 11:42 AM (in response to holdrege)
Mine is loosing around 1% every 2 minutes and that is with it sitting on standby with all apps CLOSED and no Bluetooth or WiFi on !!!!!! Hot little thing as well, 97 degrees F
Restored IOS6 but didn't fix the problem.
Looks like a trip to Apple tomorrow for a refund. Good job I didn't sell my iPhone 4.

Just went and visited my local Genius Bar and they said, "definitely not normal" but as far as their diagnostics were concerned everything seemed fine. They replaced the phone and I'm in the process of re-syncing everything and restoring the phone. I will update on my findings in a day or so once I have time to take it for a decent test run. FINGERS CROSSED!

You are to blame because you are holding the phone wrong ....
