Upgraded Verizon HTC Touch Pro2 (Windows Mobile 6.5) battery drain status

I have a Verizon HTC Touch Pro2 that I've upgraded to Windows Mobile 6.5 (see:  Windows Mobile 6.5 update now available for HTC Touch Pro2). After the ROM upgrade, I noticed a rapid decline in battery life (see:  Worse battery life after upgrading to Windows Mobile 6.5 on Touch Pro2. After doing some investigating, I discovered that my turning the Bluetooth off, my battery life would return to normal. (Location Service was ON)

Now, I've run a different experiment today. I turned the Bluetooth on, but I turned the Location Service Settings off. Guess what happened? My battery life is back to normal.

So now I'm confused. Is the problem in the Bluetooth or the Location Service? Are they connected? I'll need to conduct a few more experiments to see what happens. The Location Service Settings are a bit confusing. You have the following options:
  • Improve location service by collecting location data at any time when device is in use (On/Off)
  •  Programs that use location service
    • HTC location service (check box) - checked
    • Automatically decline location service in all HTC software that attempts to use location (check box) - checked
You can see that I've checked the boxes for the last 2 items. Let's see what happens. My Bluetooth is on and Location Services are "on" with both boxes checked. Will the battery be drained in a few hours?
