i have used this app before and i think it is a good concept. However i have found a app that resets your battery's S-O-C % (state of charge) while the phone is running.
it is called smart.cab and it does alot of other stuff too
for battery level go to
close>battery monitor>soc reset
its originally made for the omnia i8000 but i use it on a i920...........................just cant access some of the functions
