Btw., when switching the battery status (e.g. discharging -> plugged in = idling due to charging thresholds) even more fields report wrong data. upower: state: charging energy-rate: 14,878 W time to full: 49,8 minutes kernel: POWER_SUPPLY_STATUS=Unknown POWER_SUPPLY_POWER_NOW=0 One gets the outputs in the previous post after booting in the 'idle' state. I second this "Plugged in" status is useful.
I am seeing this issue too on a Samsung laptop which limits battery percentage to 80% if enabled in BIOS.

Battery status is 'charging', yet my battery already reached my 89% charging treshold.

This is kind of a duplicate of #70321. But it seems to me, that primarily the wacom issue was solved, so I report the battery issue again, since the status isn't reported correctly after all. For some batteries charge thresholds can be set (some thinkpad models and maybe others too). If plugged in and within the charge limits, the battery does not get charged but idles. It can bee seen as a fourth status besides 'charging', discharging', and 'full'. The kernel reports 'unknown' in my case: cat /sys/class/power_supply/BAT0/uevent POWER_SUPPLY_NAME=BAT0 POWER_SUPPLY_STATUS=Unknown POWER_SUPPLY_PRESENT=1 POWER_SUPPLY_TECHNOLOGY=Li-ion POWER_SUPPLY_CYCLE_COUNT=0 POWER_SUPPLY_VOLTAGE_MIN_DESIGN=10800000 POWER_SUPPLY_VOLTAGE_NOW=11631000 POWER_SUPPLY_POWER_NOW=0 POWER_SUPPLY_ENERGY_FULL_DESIGN=56160000 POWER_SUPPLY_ENERGY_FULL=55710000 POWER_SUPPLY_ENERGY_NOW=38680000 POWER_SUPPLY_CAPACITY=69 POWER_SUPPLY_CAPACITY_LEVEL=Normal POWER_SUPPLY_MODEL_NAME=42T4653 POWER_SUPPLY_MANUFACTURER=LGC POWER_SUPPLY_SERIAL_NUMBER= 292 But upower 0.99.3 reports 'charging': upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: BAT0 vendor: LGC model: 42T4653 serial: 292 power supply: yes updated: So 14 Jun 2015 18:32:01 CEST (16 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: charging warning-level: none energy: 38,68 Wh energy-empty: 0 Wh energy-full: 55,71 Wh energy-full-design: 56,16 Wh energy-rate: 0 W voltage: 11,631 V percentage: 69% capacity: 99,1987% technology: lithium-ion icon-name: 'battery-full-charging-symbolic' Shouldn't the 'unknown' status gets looped through so that userspace programs can react to it?
