Public bug reported:

gnome-power-statistics sometimes gets the wrong value for Energy when
full, causing the battery indicator to show nearly empty when it's
nowhere near empty.

For example:

slice 14:29:01 ~$ cat /sys/class/power_supply/BAT0/energy_full
67410000
slice 14:31:52 ~$ cat /sys/class/power_supply/BAT0/energy_full_design 
67000000
slice 14:31:57 ~$ cat /sys/class/power_supply/BAT0/energy_now
28310000

Meanwhile, gnome-power-statistics is correctly showing Energy (design)
as 67.0Wh, but Energy when full as 633.7Wh, roughly a factor of 10 too
high. Interestingly, although it then calculates that the battery has
about 6.1% left, it still shows the time remaining correctly (about 2
hours).
