I've actually noticed that ever since I've started using Tear, my N810 will sometimes burn through its battery even with no program running and no open WLAN connection. I've hesitated to bring this up so far, since I don't know yet if it's really caused by Tear. It's only a suspicion since it started happening when I started using Tear. Maybe Tear doesn't quit properly, leaving the process hang around using up CPU even after the window is gone. Or maybe the Tear task navigator plugin is the culprit. I haven't really had time to investigate with top etc. yet.
