iOS 5.1 Battery

That's about what I get with my iPhone 4. Most of my usage is browsing. Very little from voice and music. That could explain why I only get about 6 hours of usage when I see others with hours more.
If you don't use any push, it's possible to get rid of every push connection.
Battery life is great like that, I can get 7-8 hours of real usage and 4-5 days standby
Causes of the phantom push connection is the "Store" in settings, sign out and it will go, assuming nothing else has push on, you might need to log in and then log out to clear it since sometimes you can be invisibly signed in without it saying you are signed in (you can check it by clicking "create new account" then cancelling it, and you'll crash to the home screen, upon returning you'll be magically signed in
But with push enabled, the polling is very aggresive... even on wifi it polls a little, but I worked it out as being about 1-2 phantom minutes of usage every hour, whereas on 3G the phantom usage varies wildly, I've had up to 6-7 hours of "usage" in a day where I've maybe used my phone for 3-4 hours at the most.
Another interesting thing -
100% charge phone
Go to bed with wifi on, and another night wifi off.
I found -
Wifi on = 100% when I woke up (8 hours sleep)
Wifi off = between 95-99% when I woke up (8 hours sleep)

Okay, last night put the phone in 2G mode and I now have 100% still. And that extra usage that came from no where is not there.
So look like its something wrong with 3G.
I'll try with wifi on over night next to see what happens
Well, I am neither of those two gentlemen - or one gentleman, as you are hinting - and only came across this thread a minute or two ago while googling IOS 5.1 battery drain. I don't have an iPhone, but a fourth generation iPod touch and battery life has fallen dramatically since updating to 5.1. I was baffled at first but keeping an eye on it and ensuring I wasn't leaving any apps running showed that battery life is a lot worse than it was with IOS 4.x. The odd thing is that some people say their battery is performing better, so I don't know what to make of it all. I just hope there is an improvement in the next update because this is now beyond a joke.

Aeroplane mode will do that. It stretches battery life right out.
I also found in an area of absolutly no coverage on 3G that it wouldn't switch to edge and find a signal but turning 3g off it connected to edge straight away. Just goes to show it stays on 3G way to long trying to find a signal.

This is with an hour or so calls, lots of texting, video, pictures, app usage...
i would say 5.1 is very good.

Not happy with battery life at all, it really sucks. I have chargers every where and feel that I am constantly going charger-to-charger to keep the damn thing going. It drops from 100% to 80% in no time at all and with any moderate use that sucker is dead well before the end of the day.
I really hope Apple increases the size of the iPhone 5 battery especially if LTE is coming or it will only get worse.
Apple "Genius" says 20% drain overnight with phone just sitting there is perfectly normal and acceptable.

The new iPhone (or iPhone 5) better have a bigger battery. Check out the specs for the forthcoming EVO 4G LTE below. 2000 mAh
Done a restore on my 4s the other day as a few apps wherenot working at should. Amazed with the improvement of battery life since. Was only getting approx 5hours usage before my restore.
This is totally off topic, but have you seen the video of the female that can't figure out how long it takes to go 80 miles if she is traveling 80 miles per hour?Unless I misunderstood, they're getting a minute of screen time per minute
Haha I didn't plug it in, I have two batteries in my phone and left it in my car playing music one night and I thought that was rediculous and took a pic! Haha with normal use I get about 22 hours per charge.
