I am draining my battery fairly quickly also... I am forcing myself to not use live wallpapers, various widgets, etc. and I still drain it fairly quickly. I use ATK like it's my job, and still can't manage to keep my battery full, or at a decent level.
It's been recommended to not use task killers with froyo
Get NetMeter and sit on the show tasks screen for a few minutes and see what app is taking up the cycles.I am having the same problem and accidentally posted a new thread asking the same thing. I am experienced android user and can't figure out what is draining the battery. The batter manager is no help. I thought it was maybe tango running in the background but uijnstalled and having the same issue.
I tried this, and then only reinstalled apps the apps I had that don't use updates, i.e. SpeedTest, Angry Birds, Droid Light.I heard you could do a factory reset, then reinstall. It has to be a rogue app if you were already having good battery life previously
That looks like a sweet app!i have installed Watchdog Task Manager
