Horrible Battery life with CM7 on 3g/4g

On my phone when I have 3g or 4g on I get HORRIBLE battery life. Like 4hrs at max. I can practically watch the percentage go down (like 1% a minute)and the phone gets super hot. I have bumpcharged / calibrated like 10 times now.

On wifi its fine. Amazing even. I could go days with it. And its not like I have an app thats running. Android says its all the cell usage.

Im using CM7 rc1.5.2 and MR2.5, As I was typing this post I flashed MR2 to see if it helps.

Anyone have any other ideas? Thanks :)

Figured I'd post up my last charge:
Cm7 1.6.1
Latest leaked radio
oem extended battery
Wifi on all the time (set to stay on when screen is off)
KangBang 1.0 BFS at 1ghz, ondemand
I use the phone a decent ammount, and use data constantly (remote desktop, and tether my iconia to it for work). I also use it as an mp3 player whenever i'm in my car.
Just got 3 days, 3 hours, 15 minutesbefore plugging it in. Phone was at 4% remaining.

This is with an exchange account,and 2 gmail accounts set to push.
Facebook and Google+ notifications off (pointless to have them on with email notifications setup), and manually running ATK (pretty extensive ignore list setup for system apps).
Also, i disabled (deleted) dsp manager. While it's a neat feature, i found it absolutely destroyed the battery.

how did you delete dsp manager? I don't use it.....
I personally prefer Root Explorer. Just rename the apk to .apk.bak, or delete it. You could also use adb, I just find it quicker to do it on the phone.
