I 100% found the source of battery problems

disabling location services when your not using it, turning off bluetooth and push email, turning off wifi when your not near a wifi point is what alot of people probably dont do and complain of battery

when i first updated my iphone 4 to iOS 5, i noticed Bluetooth was on, there was no symbol but it was on so maybe your guys Bluetooth's are on?

I'm 99.9% sure all of the Location Services>System Services can be turned off without any issues.

Location Services = GPS. There are still plenty of dumb phones which don't have GPS built-in and which find cell towers and set their time zone just fine based on the tower. I'm positive the 4S will do that as well.

I've disabled all of the System Services for now and my phone seems fine.

Haha, all of us have already tried disabling that.

I really can't stand when people make topics like this.

I'm getting GREAT battery life compared to my 3GS. I currently have brightness set to 3/4 way, I use it a lot at work including streaming online radio. From 6AM to 5PM when I get home, I still have 40% left. On days when I hangout with my bf, I get home around 11PM, I would have sometimes 10% left or slightly more.

On my 3GS, I had to charge it at least 3 times during the day.
