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

    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 – JonasCz Sep 2 '16 at 6:12

    I have the same problem but I don't have an iPhone plugged in (I don't even have an iPhone!) or any other external device. Only a MicroSD card but upowerd hogs my CPU even with no MicroSD inserted so there must be some other explanation for it. – Vistaus Nov 2 '16 at 15:48

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

    Thanks, this helped me too! I "trusted" the computer from my iPhone and that fixed it. – Aaron Apr 2 '17 at 13:28

    Wow, spot on - ripped out the cable: Gone. Psyhco. Didn't help to kill it either, it just came back. (But @JonasCz should have the credit!) – stolsvik Jul 20 '17 at 20:29

  • Why iPhone8 can not remember the trust option each time plugged to Ubuntu 16.04? – Honghe.Wu May 18 '18 at 5:42
