I noticed this bug when the system settings screen showed a battery
level of 94% after 59 hours of idling. But I am not sure it is an
userspace bug:

phablet@ubuntu-phablet:~$ cat /sys/devices/platform/battery/power_supply/battery/uevent 
POWER_SUPPLY_NAME=battery
POWER_SUPPLY_STATUS=Charging
POWER_SUPPLY_HEALTH=Good
POWER_SUPPLY_PRESENT=1
POWER_SUPPLY_TECHNOLOGY=Li-ion
POWER_SUPPLY_CAPACITY=93
POWER_SUPPLY_BATT_VOL=4186
POWER_SUPPLY_BATT_TEMP=260
POWER_SUPPLY_TEMPERATURER=6644
POWER_SUPPLY_TEMPBATTVOLTAGE=508
POWER_SUPPLY_INSTATVOLT=4186
POWER_SUPPLY_BATTERYAVERAGECURRENT=462
POWER_SUPPLY_BATTERYSENSEVOLTAGE=4186
POWER_SUPPLY_ISENSEVOLTAGE=4275
POWER_SUPPLY_CHARGERVOLTAGE=4702
POWER_SUPPLY_STATUS_2ND=Discharging
POWER_SUPPLY_CAPACITY_2ND=50
POWER_SUPPLY_PRESENT_2ND=0
POWER_SUPPLY_VOLTAGE_MAX_DESIGN=4200000
POWER_SUPPLY_VOLTAGE_NOW=4186000
POWER_SUPPLY_TEMP=260

It shows POWER_SUPPLY_STATUS=Charging because I had to connect the USB
cable for phablet-shell. POWER_SUPPLY_CAPACITY=93 must be wrong, it is
an impossible value after two and a half days of idling with radios
enabled. I rebooted the device and nothing changed.

So it might be a kernel and/or hardware issue.
