errr how does it kill the battery? i use it on the tytn II, and its a great solution.
I need to run some proper controlled tests to verify, but I found that even when the device is asleep, the power consumption is much higher than it is without S2U2 running.
Having said that, I'm going to try it installed and not installed over the next few days to attempt to eliminate other factors.
I'm not the only person to notice this problem, though. All the comments I've seen about it have come from people who own one of the newer HTC devices, such as the Touch Diamond or the Touch Pro.
