Battery status is pending-charge on some devices when charge is 100%

Some Asus machines report the battery as "Not charging" when the battery is above a certain level (~95%). The problem is that when they are at 100% charge they also report "Not charging", instead of reporting Full.

I've tried to get it fixed in the kernel, but it received a lot of resistance and it looks like it is not going to be accepted: https://patchwork.kernel.org/patch/10666547/. So I think we'll need some heuristics in upower if we want to have it fixed.

This is the battery info from upower --dump:

And from the kernel:

$ cat /sys/class/power_supply/BAT0/status 
Not charging
