I found this over at ppcgeeks guys changing this in ur registry suppose to give u more batttery life .I did this last nite and found out that this does indeed work on my pro and may work on urs as well !
Dear Chefs/Users,
I wanted to share with you, what I believe to be the source to the better battery life on my 2.4.X Roms.
[HKEY_LOCAL_MACHINE\Drivers\BuiltIn\Battery]
"PollInterval"=dword:4E20
I've shared the fix with Ghetto, and he has confirmed, and will likely incorporate the reg into future iterations of the kitchen.
Original credit goes to DCD (XDA) as I noticed this was a registry from his old Titan Kitchen.

Here is something else someone found on another site :
Here's something everyone can use to make registry changes easier:
Code
http://ceregeditor.mdsoft.pl/
Download and install this program, it runs on your computer. Just connect using activesync and it will read the registry from your phone and allow you to make edits from your computer itself. I make so many reg edits that it's a pain to do it all from the phone.
Pro Tip: Make sure you go to Tools - Unlock Registry first so it will allow you to commit changes to your phone.
Also, you can save favorites and make cabs from reg entries etc, this editor is pretty nice.
Btw if you change the 5000 to 20000 and not do anything else, that'll be just fine. There's no need to change it Hex 4E20 explicitly, it's the same thing.

additional info to battery life.I will make changes and report back with my results

*** you will need a registry editor such as PHM, Total Commander, Resco, etc. to do the edits. Once edits are done wait for 1 minute before you soft-reset to ensure those edits have been implemented into the configuration***
