tlp is an advanced power management tool for Linux that optimizes battery life on laptops. It automatically applies power-saving settings when on battery and performance settings when on AC power.
Settings are configured in `/etc/tlp.conf` and cover CPU frequency, disk spin-down, USB autosuspend, WiFi power saving, and more.
