iPhone 4s Rapid Battery Drain and Unusual Use Stats

Hello all,

I uprgraded from an iPhone 4 to a 4s on Wednesday and switched providers (AT&T to Verizon). I had read some of the horror stories regarding 4s battery life but figured that with all of the fixes around that I'd be fine. Boy was I wrong! When I purchased the phone, the person I dealkt with at my local Verizon store told me it had a 75% charge on it and to go home and charge it for about an hour and a half then take it off. When I inqurired as to why the phone would already have so much discharge right out of the box, she said none of the phones ever come fully charged because they've been sitting in the box, etc.

So after a charge, I took it off the charger, synced my phone to add all my apps, and began tweaking my settings to:

Location Services: Off

Push Notifications: Off

Wifi: Off

Basically if I didn't need it, I turned it off, following some of the instructions on this forum to maximize battery life.

After three hours of what I consider to be very light usage (occassionally checking Twitter, Facebook, and email) I was done to the 85% range. I received a phone call (which lasted 1.5 hours) and was in the 60% range following that. I went to bed with the phone on standby and woke up 7 hours later and it was on 51% I'm on the phone for work a lot during the day so I decided to let the battery drain totally down while I was working and plug in it once it had fully discharged. Just before it shut down completely I checked the usage stats and saw that I had approximately 7 hours of usage and 16 hours of standby. This was at approximately 4:30 pm.

I took the phone off the charger at approximately 7:30 and left it sit on my desk in standby since I was doing something else and didn't need it. When I came back to my desk two hours later it was still at 100%. I did some light Twitter and Facebook surfing and an email check and it was at 99%. After purchasing some songs on iTunes I plugged the phone in the computer to sync it, which brought it back to 100%. After that I began to notice rapid discharge (approx. 1% every 5 min.) I received a phone call (approx 3 hours this time, on speaker) and by the time that was finished I was down to 55%. Usage and standby time were nearly equal. I was a bit perplexed so I decided to install the system status app to see if I could get an idea of the inner workings of the phone. I noticed that my CPU spikes drastically at times (from like 11% to 63%). I then deleted all my apps with the exception of Twitter in an attempt to determine if it was my apps pulling so much power or an actual hardware issue.  When I went to bed last night, the phone was at 55%. This morning after approximately 7 hours on standby the battery sat at 39%. After my usual email, Facebook and Twitter check it was down to 31%

My battery stats as of this afternoon were:

Battery: 24%

I'm not sure of the exact usage stats as the phone has since died and been re-charged. I believe the usage was around 5 hours with standby around 13 hours.

After looking at System Status, I found some other concerns:

CPU usage spikes from 6.2% to 25% in 30 second period (with phone not in use except for System Status app)

Memory Usage:

Wired: 11.6% (58.3 MB)

Active: 17.1% (86.3 MB)

Inactive: 8.5% (43.1 MB)

Other: 59.8% (301.8 MB)

Free: 2.7% (13.8 MB)

Root User Processes: 14 (has spiked as high as 22)

I can't pretend to understand the technical aspects but it is very frustrating to be experiencing such rapid battery drain, especially during standby. Could be there a setting I'm missing that may help increase my battery life? I'd appreciate any suggestions.
