upowerd hogging CPU while iPhone is connected

  • 772

It appears that upowerd is hogging my cpu time, I killed the process, but it has returned, and is climbing in resource consumption. Do I need upower? can I disable it?

I am using ubuntu Mate 16.04.

heres a screen-shot from the top command enter image description here

    From @JonasCz, whose comment was:

    Do you happen to have an iPhone plugged into your computer ? If so, you may need to select "Trust this computer" on the phone (or disconnect it), which may fix it: bugs.launchpad.net/ubuntu/+source/upower/+bug/861642

    Unplugging the Iphone solved the issue, or was an acceptable answer for me.

  2. This just happened when I resumed the computer this morning. Going into suspend last night I had Power Panel left open. This morning Power Panel was all greyed out and the hard disk light was flashing like a disco light show.

    I used these commands:

    $ ps -aux | grep upowerd | grep -v grep
root      2013  0.5  0.0 349976  7372 ?        Rsl  Aug11  11:12 /usr/lib/upower/upowerd

$ sudo killall -9 upowerd

    Of course now upowerd isn't running at all but that's OK it'll come back with the next reboot. I don't use it much anyway just to check when wireless mouse or keyboard batteries are low.

  3. I had a 3DConnexion device (3D Spacemouse) connected via USB and unplugging it solved my problem CPU hogging problem.
