Same problem here. Dropping about 1% every 3 minutes just browsing on wifi, not even LTE. And dropped about 30% overnight with no usage.
I'm starting to think that this may be due to restoring from a backup of my iPhone 4 and not starting fresh. Did everyone else restore from iPhone 4 backup running ios5?
I didn't restore from backup as I bought my iPhone 5 on a business trip. I downloaded minimal apps and turned off Siri "lift to activate". Anything logical is off.
I unplugged it at 8am. It's 9:20 and I have 59% battery. I used navigation for 15 minutes tops. Very nervous about battery.
I think it's the GPS / map running in the background. I closed it completely and drain has slowed significantly.
Double-tap the round button
Scroll through the list of apps along the bottom row. These are backgrounded apps.
Hold down one of the icons for a second.
Click the top left X to close them.
I closed all background apps but the maps one is likely the one causing it.
I also am very dissapointed in the Battery life. I live in an area where 4G is not available. I noticed that my map app was open in the background so I closed that and we will see if this helps at all. I hope it's that easy of a fix especially because one of the reason I bought this phone was the battery life was so much longer than my 4.
Any one else have any fixes???

I'm concerned too. Fully charged overnight. Send two emails and took three photos today ball the rest of the time it was on standby. Nine hours later and I'm down to 78%. What happened to 225 hours standby?

Same battery issue here. Received the phone - took it to work and synced it and charged up to 100% by 5 PM EDT (it had been around 75% when I started the sync). Last night, it was already at 70% battery level, then on awakening down to 40%. Maps was not on overnight - only one app for the Clock Alarm. Now, iPhone is at 15% at 3:30 PM EDT. I now have quit all currently running map based apps after reading this.
Two unrelated side issues:
1. Noted failure to engage the Lock Screen after sleeping the iPhone. Had to play a lot with controls in Settings (passcode lock and auto-lock) to get it to work again. Working now.
2. Iphone rebooted on its own (to the Apple Logo screen) yesterday while uploading apps, then when moving them from page to page, but would revert to Lock Screen when hit Off/Sleep, then the Home Button. Odd.
Ok, when I recieved the phone it was at 55%, and I used it for about a hour and it dropped fairly fast. grant it I was loading apps and running tons of them to get everything up and running. I plug it in to my MBP and synced everything up, back up and charged to 100%. Left the phone sit over night and it dropped to 95% (no big deal). Started my run tracking app (RunKeeper) and listened to music for about 80 minutes. The phone was at 50%. WAY to low for 80 minutes. I noticed there was a fair amount of apps in the background and killed all non-essential apps.. Drain stowed to acceptable levels. Overall, I dont think iOS6 is all the great at limiting background app battery drain.. Might be wrong, but it seems that way to me so far, but it has only been 20 hours
Strange. Today my phone was at 93%. I took a call that lasted 36 minutes and my battery dropped to 48%
The only thing syncing on my phone are Photos (iCloud is still restoring photo albums). all other background apps are closed and push for mail is disabled.
I too am experiencing poor battery life with the iPhone 5. I got it on Friday, charged it to 100%, unplugged it shortly after noon, and within 8 hours, it was at 20%. I originally thought it had to do with the fact that I was playing with Siri so much (I only had an iPhone 4). I had noticed that every use of Siri—even to place a phone call—used GPS. I tried the fix for that (turn off Siri location services, reboot, and then turn location services for Siri back on), and I feel like it wasn't using GPS as much, but it still does (e.g., I just searched for a contact in my iPhone, and it used GPS to search Contacts—thats pretty annoying).
As of this moment, I charged it overnight, unplugged it (it's currently on wifi), and has dropped 2% in 1.5 hours on standby. Meanwhile, my new iPad (iOS 6), which was unplugged at the same time as my iPhone 5 (i.e. also at 100% battery, and on wifi) has been both sitting in standby, and was used to reorganize some Books categories, and is still at 100%. Thus, two devices both at an equal charge and on wifi and running the same version of iOS, both essentially in standby mode for about 2 hours now, have disparate battery charges.
Thus, I am not sure if this is a software thing, or a hardware thing. Certainly disheartening seeing as the iPhone 5's extended battery life with highly-touted, and that my 1.5 y/o iPhone 4 which has gone through many charge cycles, held its battery life considerably better, even during the 2 days it was running iOS 6.
Hoping its something iOS 6.0.1 will fix.

I had the same issues - posted yesterday above.
1) I turned off all Notifications except Messages and Phone.
2) I set Screen Brightness at 30%.
3) Turned off "Push" on Mail, made it Manual only.
4) I set Facetime to use Wifi only.
Last night, iPhone battery level was 87% on going to bed, and I turned off all background apps (even the ClockAlarm used the night belore). This AM battery level is at 80% - real progress (from prior 30% overnight drop).
Still a drop, unsure if Bluetooth is the culprit, or if other drains are the cause.
