I have been using AGTL lately a lot and I like it very much, except for some reason it seems to drain the battery dry so fast that I can only use it for a few minutes at a time.

I then noticed the program always has a very high CPU usage: even when AGTL is in the background, the screen is turned off, etc. it's still using up 25-30% CPU. I did a comparison with eCoach and it doesn't seem to have a visible effect in cpu usage when it's on background or the screen is turned off... This seems like a rather big bug, I dont think there is any reason the program would need to use up so much CPU when it's not rendering anything (ie. the phone is in my pocket)? If anyone has taken a look at the source, would it be easily possible to just add a sleep into some rendering/processing loop when the screen is off/the app is not on the foreground?
