I currently use Archlinux core/linux 3.13.8-1 (base) with community/i3-wm 4.7.2-1 (i3) community/i3lock 2.5-2 (i3) community/i3status 2.8-2 (i3) and community/powertop 2.5-1 Running powertop, I noticed that i3bar consumes a lot of power Power est. Usage Events/s Category Description 2.68 W 120.2 µs/s 40.0 Process i3bar --bar_id=bar-0 --socket=/run/user/1000/i3/ipc-socket.1029 This is even more than chromium does most of the time. Is that just a bug in powertop, or does i3bar really consume that much power, and if that's the case: how can I lower the power consumption. Currently my i3status intervall is 1 sec. Here is my ~/i3status.conf # i3status configuration file. # see "man i3status" for documentation. # It is important that this file is edited as UTF-8. # The following line should contain a sharp s: # ß # If the above line is not correctly displayed, fix your editor first! general { colors = true interval = 1 } order += "ipv6" order += "disk /" order += "disk /boot" order += "wireless wlp3s0" order += "ethernet ens9" order += "battery 0" order += "load" order += "volume master" order += "tztime berlin" order += "tztime local" order += "tztime date_local" volume master { format = "♪: %volume" device = "hw:PCH" } wireless wlp3s0 { format_up = "W: (%quality at %essid) %ip" format_down = "W: down" } ethernet ens9 { # if you use %speed, i3status requires root privileges format_up = "E: %ip (%speed)" format_down = "E: down" } battery 0 { format = "%status %percentage %remaining" } run_watch DHCP { pidfile = "/var/run/dhclient*.pid" } run_watch VPN { pidfile = "/var/run/vpnc/pid" } tztime berlin { format = "%H:%M %Z" timezone = "Europe/Berlin" } tztime local { format = "%H:%M:%S %Z" } tztime date_local { format = "%Y-%m-%d" } load { format = "%1min" } disk "/" { format = "%avail" } disk "/boot" { format = "%avail" } I run i3 on a laptop and power consumption is an issue for me. Just let me know if you need any additional information. Thanks for any advice.

Please try and see if you can reproduce it with a new user on your machine (to rule out any local configuration issues) and file a bug at http://bugs.i3wm.org with an strace of i3bar (e.g. strace -tt -s 2048 -p $(pidof i3bar))Thu, 17 Apr 2014 12:45:57 +0000https://faq.i3wm.org/question/3637/i3bar-power-conumption/?comment=3671#comment-3671https://faq.i3wm.org/question/3637/i3bar-power-conumption/?answer=3638#post-id-3638I can't figure out the exact problem, but to provide a reference, with interval = 5 and similar config, I'm at 12.8 mW 272,4 µs/s 4,4 Process i3status --config /home/mo/.i3/i3status-big.conf 2.24 mW 6,0 µs/s 0,8 Process i3bar --bar_id=bar-0 --socket=/run/user/1000/i3/ipc-socket.4776 Wed, 09 Apr 2014 16:28:18 +0000https://faq.i3wm.org/question/3637/i3bar-power-conumption/?answer=3638#post-id-3638https://faq.i3wm.org/question/3637/i3bar-power-conumption/?comment=3639#comment-3639Changed intervall to 5: 261 mW 13.9 µs/s 5.1 Process i3bar --bar_id=bar-0 --socket=/run/user/1000/i3/ipc-socket.1029 Still high, but a lot better.Wed, 09 Apr 2014 16:33:59 +0000https://faq.i3wm.org/question/3637/i3bar-power-conumption/?comment=3639#comment-3639
