Re: [e-users] Lowering E17 battery use? Marc MERLIN Sat Apr 07 12:00:35 2012

I remember installing an older E17 which asked me at setup time if I set
installing on a low power device or a laptpo.

When I installed the newer e17, I didn't get that question and I have a
blng theme (A-BlingBlack).

Powertop currently says for my W500 thinkpad:

The battery reports a discharge rate of 14.7 W

Summary: 312.3 wakeups/second,  0.0 GPU ops/second and 0.0 VFS ops/sec

Power est.      Usage       Events/s    Category       Description
  4.30 W     11.7 ms/s     107.6        Process        /usr/bin/X :0 vt7 -br -no
  4.04 W     63.8 ms/s     101.2        Process        /usr/bin/enlightenment
  3.30 W     20.0%                      Device         Display backlight
  2.06 W      3.0 ms/s      51.5        Timer          tick_sched_timer
  662 mW      0.7 ms/s      16.6        Interrupt      PS/2 Touchpad / Keyboard
  542 mW    429.3 ┬Ás/s      13.6        Timer          hrtimer_wakeup

Top is showing enlightenment is using 37% CPU: for my W500 thinkpad:
 4208 merlin    20   0  472m  58m 8284 S   36  0.7  12:51.10 enlightenment      

Starting E didn't cause the CPU usage to go down, nor the battery use.

Then, with no real change on my side, powertop shows that E went down to
37 wakeups per second
  278 mW     61.7 ms/s      36.9        Process        /usr/bin/enlightenment
even though it's still using 39% of my CPU somehow:

  PID USER      PR  NI  VIRT  RES  SHR S %CPU %MEM    TIME+  COMMAND            
 4208 merlin    20   0  395m  93m  23m R   39  1.2  19:09.94 enlightenment      

Thanks for any suggestions :)
