Bluetooth Power Saving Registry Edit
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. |

No one?

David: While this may do what you say it does, it also seems to disable handsfree auto-answer. It may be worth the trade-off, though.

David: Never mind, it's working now. Thanks.

BT headset connected power drain on top of BT OFF is working out to 1%/hour for me. Mine isn't connected for more then a few hours so I'm going to go with having it as is.

Re: Bluetooth Power Saving Registry Edit
I went in and made the changes but when I tested the connection to see if it would work, the bluetooh would not re-connect. Is there another setting that I need to change?

Doesn't work for me...Bluetooth icon still shows. I have reset.
Should I turn off bluetooth? |
Re: Bluetooth Power Saving Registry Edit
I went back in and changed the settings and did a soft reset and it is working now. The only slight issue is, my phone will automatically answer if any calls come thru. Is there a way to turn the auto answer off? I checked the setting for this and the auto-answer box is not checked, but it answers on the second ring.
