You state the obvious. I don't use any of those programs. Once in a while Facebook, but since the Android app is so slow I usually have it removed. The others I never use.
I've used task killers.
I've used Juicedefender.
I've used startup auditor.
I've used spare parts.
I've gone back to stock.
I've tried several roms... Even simply aosp with nothing else installed.
I've been in great service areas and bad service areas.
Wifi... No wifi.
Sleep policy changes
DRM services.
Sprint bloatware...
Battery calibration...
Had my battery replaced...
Been through it all.
My colleague's Evo (on cyanogen) lasts longer than mine.
Don't use GPS.
Don't use bluetooth.
Don't use 4G.
8 to 10 idle
6 tops with some gaming, browsing, texting and (gasp) phone calls.
I'd like to use my phone for a change.
New phone won't solve your probs...you'll just get new ones. Fix your battery issues by logging OUT of all apps (Facebook, Lattitude, Amazon MP3, Pandora) before exiting program. If you use these just log in each time but remember to log OUT...the only problem is you have to sign in with username and password everytime. I do kill the SNS Service and OmaDRM at bootup, but I do leave GPS and background sync on all the time...I just toggle Autosync with a widget whenever I want to check email.
