A while ago, I had a post on a Linux shell command to get the current power consumption of my notebook. Recently, I exchanged my battery for a new one and wanted to keep track not only of the discharge rate but the other parameters as well to see how quickly Ubuntu would recognize that it is a new battery and update it’s capacity values, etc. as well. Turns out there is a nice shell command for that as well: ‘upower’.
$ upower -i /org/freedesktop/UPower/devices/battery_BAT0 native-path: BAT0 vendor: SANYO model: 45N1172 serial: 1255 power supply: yes updated: Sun 20 Nov 2016 17:35:31 CET has history: yes has statistics: yes battery present: yes rechargeable: yes state: discharging warning-level: none energy: 54,19 Wh energy-empty: 0 Wh energy-full: 63,13 Wh energy-full-design: 62,64 Wh energy-rate: 13,585 W voltage: 11,97 V time to empty: 4,0 hours percentage: 86% capacity: 100% technology: lithium-ion icon-name: 'battery-full-symbolic' History (rate): 1479659731 13,585 discharging
It took a while for all values to update but in the end the vendor name changed from ‘LGC’ to ‘SANYO’ and my ‘energy-full‘ climbed back up to 100% of the ‘energy-full-desing‘ value.
For more details have a look over at AskUbuntu.
