Bug description:
  the phone should switch itself off at around ~5% remaining battery.

  This is to preserve a little battery for use cases such as:

  * turn it back on once or twice for urgent short phone calls
  * prevent the battery from going into a state where it can't be charged any more
  * have enough power to turn itself on again and trigger an alarm

  <https://wiki.ubuntu.com/Power#auto-off>: "The device should hibernate
  (PC) or power off (phone/tablet) if both of these things are true: *
  there is less than 2% battery remaining * there has been more than 3%
  battery remaining at some point since the last time the device
  hibernated or powered off."
