A Linux laptop battery logging tool written in Rust.

It was built to track power usage of a laptop battery during each session. It keeps tracks of capacity (%), power usage (Watts).

The main goal of this project is to offer a tool that works on any distibution with systemd, runit or openrc.

The installation script will take care of copying the binary to /usr/local/bin and create a service. It will also create a file /var/log/batt_log.db to store the logs.

To install the tool, you can run the following commands:

cargo build --release
./install.sh

The default configuration file is located at /etc/batt_log/config.toml, it follows the TOML file format. You can copy this file to your home directory to override the default configuration, the order it will look for a configuration is the following:

• ~/.config/batt_log/config.toml
• ~/.config/batt_log.toml
• ~/.batt_log.toml
• /etc/batt_log/config.toml

• polling_interval: The interval in seconds between each log. Default is 60 seconds.
• log_file: The path to the log file. Default is /var/log/batt.log.

To uninstall the tool, you can run the following command:

./uninstall.sh
