I've found what has caused me some phantom usage today and the culprit was iMessage. I sent a picture to the wife today and didn't actually wait to see if it was delivered. I was using the phone after this and noticed the battery was depleting rapidly which was weird. Then, about 40 mins after sending the image, i got the message sent notification sound, and shortly after the message was delivered. So for 40 minutes the phone was trying to deliver the message, which was eating up a lot of battery. I must've lost about 15% battery in that time, yet after the message was sent things went back to normal. Anyone else found this?
Got a tip for us?

iOS 5.1 Battery

I upgraded last night, my battery was completely drained when I woke up (~97%). I am going to test this over the next few days, hope this is not an issue
No, we can't!
Did you spend 5 hours watching video streaming over 3G?
Did you play a graphics intensive game for 3 hours?
Did you listen to music from the iTunes Store for 5 hours?
These different scenarios use different amounts of battery. It would be pretty good to get 5 hours of battery life while watching video, but that would be unimpressive if you were simply listening to music with the screen switched off.
Do you have Push Notifications enabled?
Any push email accounts? If so, how many?
Was Bluetooth turned on?
What about Wi-Fi?
Have you changed the brightness setting?
Something is using Location Services in the background. Do you regularly use Apps or features that try to locate where you are?
The amount of time presented doesn't sound too shocking to me, but it really does depend on how you use your phone!

Two hours of music on Spotify from offline playlists, so no streaming.
One hour of browsing the interwebs, Facebooking and Twittering using Wi-Fi.
Thirty minutes playing Guitar Hero.
Twenty minute phone call.
One hour iMessaging / Whatsapping & misc procrastination.
Bluetooth is always off and brightness is set to 100%. I have my email fetched every half an hour and I have Google Latitude background updating enabled & that updates when I'm on the move at intervals, which doesn't use a lot of battery.
I don't use the battery percentage but I'm only going by how much battery I have left when I get home. The battery consumption has increased since updating to 5.1 even though I'm not using my phone more than usual, there's no doubt about that.

Yeah that doesn't seem right. I've been getting twice the battery life, but I don't have the brightness up all the way.
OK, after having spent more time on 5.1 I'm not at all satisfied with it... Check out these pictures; note the time in the 'usage' column compared with the battery drain. Since I took it off the charge this morning, I've had two phone calls (about two mins long each), sending and receiving about 20 text messages... And I used Facebook for literally 5 mins. The other 'usage' time, is when the screen has been turned on and just sitting next to me between the messages / calls etc. I have the screen to auto-sleep after 5 mins. The phone died not long after I took the last pic.
This is the first time I haven't had my phone last all day (and it's the one day I've used it least!).

Last two posters show location services on ie gps icon Is in picture. what's accessing the gps when your on the usage page? Mine doesn't.

5.1 is KILLING my Battery
Ever since I upgrade to 5.1, my phone dies in the middle of the night. I keep it plugged in constantly. My co-worker upgraded at the same time and gets 30 minutes on a phone call before it dies. It was so apparent recently and I couldn't figure out why and it finally clicked that me and my co-worker just did the iOS upgrade.
Prior to the update it was not constantly dying

Unfortunately Im running 5.1 now but Im still facing the same issues. Tried a restore previously, clean install. Worked well and as the days went by it started doing the same thing again.
The only thing going is Prey. No, it does not go a long way to explaining the battery drain.... Because it didn't drain like this on 5.0.1
Late December 2011 iPhone 4s software version 5.1 (9B179). Shame I had to charge at 22%

I have Google Latitude set to update my location automatically. It doesn't use the GPS constantly. I've always had it on and before 5.1 it didn't affect my battery life in any major way, and I don't think it is now.

After updating to 5.1, the battery issue is now worse.
I came home today with 13% left on the phone, turned wifi on, and just wanted to update an app, the phone turned itself off immediately. I had to connect it to the power for it to start charging (indicator says the battery is empty) before charging it again. This is not the first time, I can see my battery at say 70%, after turning my wifi on, the battery immediately drop a few percentage, e.g. 65%.
I go out in the morning with a full charge, with emails, reading Flip-it and Whatsapp, altogether probably about 1.30 hours per day. My batter would be about 15-20% by evening.
Aiks.

This update has done wonders for my standby time. I can't say the same for usage though. I can surf the web on 3G for 5 minutes and lose 2% of battery life easily.
Usage: 4 Hours, 58 Minutes
Standby: 1 Day, 3 Hours
16% remaining

The purple location services icon next to the battery percentages in all three images show that you are using location services. If you don't know that location services is an enormous battery drain, you are not fit to use an iPhone. ;-)
5.1 shockingly seems to have fixed my battery. on 5.0 and 5.01 I was dropping a good 10-15% per hour without even touching the phone. Within 30mins of installing 5.1 I noticed the battery hadn't even dropped 2% so the people on here who say "you've only had it installed an hour, You have to recalibrate your battery and reinstall this that and the other" are lying.
It's great now, managed to go over a day without recharging, spent about 1.5/2.5hrs playing games earlier which is probably why it's dropped so much. Could have been still up in the 60/70% mark had I not. + I simply installed 5.1, did a hard reset then let the battery drain all the way down (took forever on 5.1 for once) then recharged upto 100% now it's great.

You definitely need to let it go to 0%, switch itself off, and then charge right back up to 100% (uninterrupted) after installing 5.1. I don't think there's any need for a reset though.
The improvement I initially saw after 5.1 proved erratic until I let the above happen - since then (for a week now) the battery's been consistently excellent.
