At least 3-5 minute gap between removing power cable and system notifying of event

[Wise Melon]

I have noticed something very strange after upgrading to Ubuntu GNOME 16.10 with GNOME 3.22, and that is that if:

 - My laptop is fully charged and I remove the power cable:
   1. The indicator in the top right hand side of the screen changes from the icon indicating that it is fully charged to the icon indicating that it is charging, but not fully charged.
   2. In about 3-5 minutes (longer if I suspend my machine mid way during this time span) I will hear the noise which signifies that my machine has disconnected from the power cable and the icon will change to the normal one which indicates that the machine does not have a power cable attached to it (the time indicator will also show how long until the battery runs out instead of how long until it is fully charged).

 - My laptop is not fully charged and I remove the power cable:
   1. The same happens as for the previous bullet point, however step 1 is skipped as it is not fully charged yet.

  - Either or the above bullet points, however I attach the power cable instead of removing it:
    1. All of the expected (the noise and the icon change) happen immediately.

I have described this with the Adwaita icon theme, however it is icon theme independent.

If this is of any relevance, I have a Lenovo B590 laptop.

I initially reported this issue here: https://bugs.launchpad.net/ubuntu-gnome/+bug/1642718 But thought I should also do so upstream.

I first started off by reporting this issue to the upstream GNOME Shell project, however we established that the issue is in UPower rather than GNOME Shell: https://bugzilla.gnome.org/show_bug.cgi?id=774717#c7

I have UPower version 0.99.4-3 installed.

After communicating with the upstream GNOME Shell project it has been found that this issue is more likely in UPower: https://bugzilla.gnome.org/show_bug.cgi?id=774717#c7
