Comment 9 for bug 1470020

When in this state we should check
/sys/class/power_supply/battery
for the level there and also from
upower -i /org/freedesktop/UPower/devices/battery_battery
Also the dat files from /var/lib/upower

Not sure how ubuntu could prevent the phone from booting for a short time like that, I would assume this is under hw/fw control
