i've just re-installed on 2 8820
lets see it overnight hope it's just because i'm using the older minimoni on them last time (v0.30.0) now using 0.30.4.. (last time i use v0.30.4 only on the 8300)

but i think it's not because other program, because after i remove minimoni, my battery life went normal again, when i use minimoni battery life decreased by (around) 15% in 4 hours, whitout minimoni it still showed full capacity
