Ok so I got UD 8 runnin p3 1ghz. After full charge I goto work and after 4 hrs of running either pandora or iheart radio, my battery is usually around 20%. Is that normal? Also I underclock to 400 mhz but I don't think its making a difference. Is the battery dieing? I have to charge almost twice daily on heavy use of internet or whatever. Also playin gameboid I get maybe 1.5 hrs on full charge.
