Have fb,skype, gtalk online all time + bt handsfree + 3 mail accounts checked every hour + 1-3 hours browsing , connection 2g/wifi (autoselected)

CPU 250-900, custom voltage profile, no smartreflex

Battery goes from fully loaded in morning to about 50%-60% at 6-8 p.m. when hard play (programming) kicks in, so i put charger in .

There is something eating your battery, check if your wifi power saving is turned on.
