Supposedly non-running application drains battery. How can it do that?

Anytime I've installed the free version of Torque (an OBD engine diagnostics tool) I end up having to uninstall it as it uses up a huge amount of my battery life. But it's doing it while it apparently isn't even running!

I can exit the program from it's menu and if I view it in Manage Applications it is not listed as a Running application and the Force Stop button is ghosted. From that I have to conclude the program is not running.

Yet Battery Use Details always show an unnamed application using between 20 - 35% of my battery and the Force stop button is ghosted. It is only when I press Application Info on that screen that I see the program identified as "Torque (free)". If this program isn't ever running, then how can it be using up most of my battery?!

 

Thanks but something associated with Torque is definitely causing my extended battery to last 2 - 3 hours instead of the typical 24 hours. My phone is dead at that point, not just pretending to be low on battery! I have to uninstall Torque in order to get my battery life back to normal. It is a big disincentive for me given that I was about to buy the pay version.

 

I'm pretty certain that BT is involved in some way because Torque when it's running will display that it is constantly searching for a BT connection with the OBD device (which usually isn't even connected to the car). BUT there's no way for me to prevent this - Bluetooth on my phone is never enabled that I can see (I have a widget that displays BT status so it's easy to tell when it's on).

I suspect that after exiting Torque (yes, exiting using the Exit function in the program's menu) that specific aspect of Torque continues to operate in the background.
