All tabs have their page loaded. So, there's no live activity going on. Maybe the gmail tabs might have some activity in the background. I was surprised to see IceDove (ThunderBird) to be using so less power. My IceDove setup is pretty heavyweight with 2 IMAP a/c (1 IMAP + 1 D-IMAP) + RSS Feed + Leafnode NNTP. Perhaps there's room for improvement in the power consumption for rekonq. Reproducible: Always Steps to Reproduce: 1. Run rekonq while on battery. Actual Results: Keeps the cpu awake Expected Results: should be consuming lesser power.
