o.o ....Since no ones really posting the total amount of hrs it took for battery to drain, I assume that: 1) The battery is pretty much useless as it acts radically, sometimes jumping from 8 to 1 bars. 2) The battery is sometimes not fully charged because n900 does not detect the mugen batteries design properly... 3) The Mugen battery and It's Cover gives a hell of a lot of problems... Correct me if I'm mistaken? plz
