Well Pm evildragon and he suggested that I clean the battery contacts of the gp2x and that should take care of the 10-15 minute battery draining issue the gp2x was doing. Well I bought part# 640-4345 Precision Electronics Cleaner spray can and I probably didnt have to remove the whole back cover of the gp2x with the 4 phillips screws because looks like I could have done it by just removing the battery cover, anyways I sprayed some cleaner on some q-tips and started rubbing/cleaning the contacts and I put in fresh 2650mah batterys same ones as you see in my threads about battery issue and so far I played with the gp2x on for hour in a half straight and still no red light on the gp2x came on and went to the settings and abttery and still shows full.
So I guess it might have worked, its something you guys can try.
