I tried using AIM, but it goes through the battery pretty quick and erratically. I recently switched to ebuddy, and I like it a lot more then AIM, but it also destroys the battery. Ebuddy has a power save mode that I am going to try next, but I don't see why battery life is this bad with an IM program open. One of the few things I miss from my Pre is that I could be signed into AIM on the default WebOS messaging program and there was a very minor difference in battery life between when I was signed in and not signed in. Anyone have any suggestions?
