Saving battery life on linux using powertop

Most distributions come with a handy tool called powertop, that is able to automatically set kernel parameters to save energy.

sudo powertop --auto-tune

Settings are not permanent, to you can use the following snippet to create and load a systemd unit file to load the settings after rebooting your machine:

cat << EOF | sudo tee /etc/systemd/system/powertop.service
[Unit]
Description=PowerTOP auto tune

[Service]
Type=idle
Environment="TERM=dumb"
ExecStart=/usr/sbin/powertop --auto-tune

[Install]
WantedBy=multi-user.target
EOF

systemctl daemon-reload
systemctl enable powertop.service
systemctl start powertop.service
