Does anyone here have a slightly loose home button? I got mine exchanged a little while ago for the battery issue and stuck pixels, now I have this but my battery is fine, I already tried to go back for it and they said it was fine. Just wanted to see if it's normal, please say if you have a loose button
apple forgot that point , that why they not rebuild battery on iphone 4s used the same battery ,
A faster processor doesn't necessarily require more power since it may accomplish a task more quickly. For a given task, the increased power consumption may be offset by the shorter burst of processing time, actually using less power. It depends on the task. See this analysis of the iPhone 4S vs. the iPhone 4 from Anandtech:

iPhone 4S battery--wow, they weren't kidding!
Just finally got a 4S (with updated firmware). Charged fully over night. Listened to music for about an hour commuting into work. Normal usage. Down to 25% battery power by around 11:30 AM. Turned Siri off, brightness way down, location services off. Hit 9% at around 1:00PM. This sucks!!!

That sounds very unusual. My iPhone 4S usually drops from 100% to 97% overnight. I used it over an hour yesterday on the web (fairly heavy usage) and it was still around 70%. Are you sure you didn't have anything else going on?
As with any device, there is a break in period for the battery. Give it a few more charge cycles and you'll see it's life get better.
I think you need to look at your other software if you are out of power at 1pm. Any social software polling the servers?
Is ther some sort if prolem with the batery?!?! 
We are should discus each others stats here. Heres mine.:

I got 30 hours of standby and 2 hours usage on mine, and still had 30% left. I found that notifications were turning on my screen every time an email came in. Turned that off and my battery rocks! YMMV.
The battery is NOT the same in the 4 and the 4S, ifixit.com will prove you wrong as they always disassemble new apple stuff down to the hardware just to inspect every hardware change there is besides giving us a guide on how to disassemble and reassemble these things!
That's good i guess, depends on what kind of usage though, wifi browsing? Gaming?
That's very good
I normally get about 3 hours ish by that amount. Although its normally in standby for a fair bit too.
Yes, you are correct. The 4S battery has almost 1% more capacity than then battery in the iphone4. (5.25Whr vs 5.3Whr) So though technically they are not "the same", in practice a 0.95% capacity difference is negligible. See battery photos at ifixit.com
Nothing special running. I've only had it for a couple of days. I've been experimenting closing all kinds of stuff--not seeing a difference. Also, what's the point of having all this cool capability if you have to turn it all off? Very disappointed in this device so far.
Restore as new in iTunes. Run it without apps and mail setup. See if that continues. Should cure it. You should get at least 24hrs of standby with 4-7 hours of screen on usage out of a 4S.
