It comes with a command line tool (also called upower) that, among others, allows querying the battery history and statistics. UPower is an abstraction for enumerating power devices, listening to device events and querying history and statistics. Get Linux laptop battery information using UPower.

You can also install battop from AUR on Arch Linux Manjaro, and from source, using cargo. Sudo install battop-* /usr/local/bin/battop Next, use the following command to install it to /usr/local/bin: To install battop, grab the binary from the tool's GitHub releases page, and place it in your home folder. As for the information it can display, this includes charge state, voltage, battery discharging rate, temperature (this didn't work for my laptop though), battery capacity information (current, when full, and full design), time to full / empty, charge cycles count, and more. The tool runs on Linux, macOS, FreeBSD and DragonflyBSD (no Windows support yet) and it supports multiple batteries. ![]() Hsphfpd reports battery status (and other stuff) through DBus, so to get it from the command line, you can just do dbus-send -system -dest=org.hsphfpd -print-reply /org/hsphfpd/hci0/dev_XX_XX_XX_XX_XX_XX/hsp_hs .Get string: string:BatteryLevelīoth of these are available in the AUR, if you use Arch Linux.Battop, or rust-battop is an interactive viewer similar to top, htop and other such utilities, but for battery information / statistics. Even though these are both still prototypes, they seem to work very well. There is a version of PulseAudio patched to use hsphfpd. That way, PulseAudio and whatever can both use the headset at the same time. Hsphfpd is specification with some prototype implementation used for connectingīluetooth devices with HSP and HFP profiles on Linux operating system.īasically, since only one program can communicate with the headset at once and it wouldn't make sense to implement battery level reporting in an audio server, nor implement audio in a power management software, it moves that functionality to an external daemon. Only one program can open a socket to talk to the bluetooth device, so it ends up fighting with PulseAudio over it. If I understand the problem correctly, that happens because ![]() I'd been using the Python program from clst's answer for some time and although it worked, it required me to connect, then disconnect and run it again.
