Hello folks, is there a tool in Linux to track how much current the battery is pulling during charging? In Android there is Ampere that does this, and I’m looking for something similar. This nicely shows for example that my Android device is charging the battery with 1.5A right now.
The voltage, state and current draw and other cool stuff can usually be found from /sys/class/power_supply/BAT0/ you just have to make a small script to calculate what you need from that. This requres some knowledge, but it’s one way to do it.
powertop shows discharge rate in W, Joules consumed since last charging and estimated remaining time in the “Overview” pane.
I am not sure, but maybe upower could be useful. upower -d
will dump all available information.
This is exactly it, thanks! It doesn’t show the current, but it shows the voltage and the power and it can be calculated from it.
Pro tip: Add an alias for it into your .bashrc
to nicely view battery level in TTY. In my case I did alias battery='upower -i /org/freedesktop/UPower/devices/battery_BAT1 | grep -wE "percentage:|time to empty:|state:|energy:|energy-rate:|voltage:"
which shows me this:

i use lm-Sensors because it also shows temperature data, which is useful for what I do.
What DE are you using? Gnome and cinnamon have extensions for it
