All I did was remove the yubikey and put it back in, and unload wlan0 > Yubikey was showing 6W, so I removed it. that didn't change the discharge= rate: The battery reports a discharge rate of 19.9 W The estimated remaining time is 3 hours, 23 minutes Summary: 1196.2 wakeups/second, 74.9 GPU ops/seconds, 0.0 VFS ops/sec and = 16.6% CPU use Power est.

No real change either (little drop from removing wireless, but not 10W) The battery reports a discharge rate of 17.8 W The estimated remaining time is 3 hours, 43 minutes Summary: 1155.3 wakeups/second, 81.8 GPU ops/seconds, 0.0 VFS ops/sec and = 7.9% CPU use Power est.

I know that's a lie. I removed and power went up 0.4W (normal variance unrelated to yubikey).

It's impossible to get real battery usage and due tuning with it present. Thanks Marc -- = "A mouse is a device used to point at the xterm you want to type in" - A.S.= R.
