I'm just starting to muck about with a bit of dev (Beginning Android Games is good btw, only around 20 quid on Amazon); is there some way I can disable battery charging over USB while I'm sending code and debugging? Having a full battery and staying connected to a charging source for prolonged periods is what usually wrecks laptop batteries within a couple of years. Ideally other than modifying a USB cable to only have the two data lines intact.
