Erel,
Good question to me.
For this purpose, I keep the device on while turning the backlight OFF (from Settings).
I know this only saves the battery from using it power for the backlight.
Still it consumes power because the device is not OFF.
Could you suggest how to turn off the device while maintaining the application runs in the background?
The device shall also be able to be turned ON again after a predefined time.
Homework....
