Under "Settings", there is an option (under the section "When application is locked") where you can select "Turn off screen completely". Select this option and the screen will not draw any battery, but the application will still record the training.
I use run.gps on HTC Touch Diamond 2 and it used to record while device was in sleep mode. Now, it doesn't. It stops recording when device is put to sleep and starts when device is turned on and connects the two points.
Somebody please help.
I have to keep the device always on and it chews up my battery
