With this profile, my battery was 51% at 23.00 PM after been fully charged at 8.00 AM I have corrected underclock profile by locking the frequence to 250 (Min Freq = Max Freq = 250) because the Call UI is not usable at 125 Mhz...wow, with kp48 and batterypatch my battery was draining very fast...with this "combo" my N900 battery acts like my N95
