Every since i purchased my Diamond and my Touch Pro, i have noticed that i have had EXTREMELY poor battery life, even with power tweaks and different roms on both devices. I have been able to narrow down the cause of this(or at least one of them). If you are like me and having a bluetooth headset is a necessity, I am sure that you have noticed that once you turn your headset on and it connects to your phone, the connection is ALWAYS on. I have searched through the registry and found a tweak that as far as i know, have yet to be used. This tweak is a power saving measure that only opens the bluetooth connection when either a call comes in, or you make a call. Otherwise, it closes the connection to save power. I use this tweak on every rom that i change to, and have noticed better battery life

*Please not that sometimes when you PLACE a call, you may have to tap the bluetooth headset button on your headset for it to connect to your phone.

With the registry editor navigate to:
HKEY_LOCAL_MACHINE\Software\Microsoft\Bluetooth\Au dioGateway

Look for "PowerSave" and change the value from "0" to "1". Press ok, then soft reset. Once the phone boots up and your bluetooth is recognized, make a test call then hang up. Your bluetooth should close the connection and go into standby. Make a test call TO your phone. The phone should wake up the bluetooth and route the call back through the headset.

If the PowerSave Dword is not listed, create a new Dword named "PowerSave" and set the value to "1" and soft reset, then follow the steps above.

"PowerSave" Configures audio gateway to conserve power when establishing audio connections.
0 - Keeps the service level connection active for the Hands-Free profile in between calls.
1 - Closes the service level connection between calls.

Hope this helps.
