i think i recalled somewhere that viber and facebook "chat" are quite draining on battery.. my im+ also, but i need msn..
kill tasks or services?? tasks should be ok, but some services esp default come with samsung ones will come back after a while.. those i dont bother to kill coz closing and starting will cause even more batt drain..

not reli. i using social hub+viber+whatsapp, not much draining observed. well of cz i'm using wifi, if 3g will be diff story. one thing is skype reli drain like crazy. so i oni sign in if others ask me for video call

ya, agree with Fallenangelz... viber dun really drain a lot of battery, old and new version. the newer version, supposedly wakes up only when u get incoming call/ message. or sth like that...
but ya... skype... i noticed it drains a lot.

just sharing some stats based on my own experience.
phone: samsung galaxy s2. not rooted and running stock/ original Samsung ROM
at almost new condition (meaning not many apps installed and definitely dun have any apps with background services running), the idle discharge rate was about 1% for every 35 mins.
after installing more apps...
background process: tweetdeck + Google reader refreshing every 15 mins; Skype, whatsapp and Viber installed. whatsapp was not running in background while i intentionally had viber running (icon on notification bar). skype, even when it was not turned on, it was actually running in the background -- that's why in the next set of data, i uninstalled skype -- i dun like apps that starts automatically, its so malware-like... idle discharge rate at this setting was at about 1% every 15 mins.
after un-installing skype (while the other things remained just about the same), idle discharge rate was at about 1% every 20 mins. this was about the same for viber version before and after the exit button. ya, no significant change for me.
overall, my phone's idle discharge rate is at about 1% every 20-30mins.
as you can see... viber running (before and after the exit button) didn't really affect my discharge rate.
