However, Ubuntu 18.04.2 LTS is unable to detect the true battery state. The GNOME battery indicator usually shows "Estimating..." or "Not charging", when the battery is at 100%. If you use the upower version 0.99.7-2ubuntu0.18.04.1 command "upower -i /org/freedesktop/UPower/devices/battery_BAT0", this is what you get: native-path: BAT0 vendor: ASUSTeK model: ASUS Battery power supply: yes updated: sex 03 mai 2019 14:33:43 -03 (4 seconds ago) has history: yes has statistics: yes battery present: yes rechargeable: yes state: pending-charge warning-level: none energy: 39,191 Wh energy-empty: 0 Wh energy-full: 39,26 Wh energy-full-design: 42,082 Wh energy-rate: 12,453 W voltage: 11,52 V percentage: 100% capacity: 93,294% technology: lithium-ion icon-name: 'battery-full-charging-symbolic' History (charge): 1556904821 100,000 discharging History (rate): 1556904821 12,453 discharging 1556904818 3,744 discharging The "state" should be "fully-charged", but instead it is "pending- charge".
