Cool, thanks for the tip and your help.
I was curious to see how my power use would be, and got about the same power
use at idle with LCD to minimum:
The battery reports a discharge rate of 12.4 W
The estimated remaining time is 7 hours, 27 minutes
Summary: 171.5 wakeups/second, 0.1 GPU ops/seconds, 0.0 VFS ops/sec and 2.0% CPU use
Power est. Usage Events/s Category Description
3.73 W 1.9% Device Display backlight
1.16 W 4.7 ms/s 65.3 Process [btrfs-transacti]
741 mW 0.9 ms/s 41.9 Interrupt [4] block(softirq)
175 mW 156.0 µs/s 9.9 Process [rcu_sched]
Then, if I turn my screen off (backlight 0), it actually seems to save another 7W:
The battery reports a discharge rate of 5.06 W
The estimated remaining time is 18 hours, 5 minutes
Summary: 79.4 wakeups/second, 0.2 GPU ops/seconds, 0.0 VFS ops/sec and 1.8% CPU use
Power est. Usage Events/s Category Description
229 mW 1.4 ms/s 13.4 Process [btrfs-transacti]
181 mW 4.1 ms/s 10.4 Process /usr/bin/enlightenment
174 mW 206.2 µs/s 10.2 Interrupt [4] block(softirq)
So the good news is that the driver sems to do fine on batteries with the
default options now.
Thanks,
Marc
