Shape,

My assumption is that GPSed keeps the GPS active even after the track has been stopped and the user has hit exit. This could be a result of not properly closing the interface to the GPS device, or probably any of a number of other explanations.

What is clear is that GPSed is the cause of the problem. It doesn't matter if it directly uses the battery (whatever that would mean), or if it makes use of services which consume power (which it definitely does).

I find your response to be very confusing, but thanks for forwarding it to the developers.
