for what it's worth, although top show it is much better, when I look with 'powertop' the story still looks not to good (but definitely much better than before Jakub's patch) It still says 26.6 of 29.1 W (>90% ?) is going to the wlan ? Seems like a heck of a lot of power for wireless lan? makes no sense. I'm not very knowledgeable of powertop, perhaps I just do not understand the display.
by the way, this isn't streaming or anything, there is chrome running, with a gmail window and some local terminals. No real network traffic at all. --- screen copy/paste ---- The battery reports a discharge rate of 29.1 W The estimated remaining time is 0 hours, 32 minutes Summary: 966.8 wakeups/second, 16.0 GPU ops/seconds, 0.0 VFS ops/sec and 11.8% CPU use Power est.
