is there a way to tell which app is in use the most/draining battery?

[aliensarecool]

my usage and stand by times often match on my 4s. i am jailbroken on 5.01 if you know of any JB apps too that might help...but i'm curious what is always running and/or making my battery drain faster than it used too

Download istat and look at processes with high CPU usage.

CPU isn't the only battery drainer.

Read the recent reviews - it seems that the app has not been updated since 2009 and doesn't work with iOS 5 and some Macs.
