Haha, here's my graph, interesting since I can get about similar performance as lq_sunshine..

Just a few pointers, turning availability off helps quite a bit. However, the MSN Haze Plugin is a major culprit! I got more than twice the battery life I had just by disabling the MSN plugin! Dont know if this has to with the number of people in the MSN contact list though.

and without the SIPs on, at night, the battery level almost literally flat-lines, which is quite amazing!
