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.
This data is available in the sysfs, I’m not aware of any apps that make use of it sadly
powertop shows discharge rate in W, Joules consumed since last charging and estimated remaining time in the “Overview” pane.
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.
What DE are you using? Gnome and cinnamon have extensions for it
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:
