How to Get TLP 1.8.0 in Ubuntu
TLP has an official PPA so far supports Ubuntu 22.04, Ubuntu 24.04, and Ubuntu 24.10.
Simply press Ctrl+Alt+T to open up a terminal window, then run the commands below one by one to add the PPA & install TLP (1.8.0 so far):
sudo add-apt-repository ppa:linrunner/tlp
sudo apt update
sudo apt install tlp
After installed the tool, either restart your computer/laptop to let it run automatically, or run sudo tlp start command to start it without reboot.
TLP is running silently in the background, and default settings are already optimized for battery life, so you can just forget about it afterwards.
But if want, user may edit the /etc/tlp.conf file or use tlp, tlp-stat, etc commands for custom settings. See the official documentation for details.
