On my HTC Desire HD I have 3 email apps. Gmail, Mail for HTC and the standard Mail app from Orange which I have not activated. I have DX Battery Saver installed...when I check what my application power usage it's saying my Mail (the Orange mail app which isn't activated) is using 65%, android system 20%, facebook 3% and so on....how is this? What can I do to reduce this big time??
