TLP

TLP is a linux command line utility for saving laptop battery power aswell as optimizing battery life.

Setup

TLP can be installed on most distributions by installing the tlp package. Afterwards the TLP service needs to be started and enabled. In contrast to other SystemD services this can be done by running sudo tlp start and running systemctl enable tlp.service.

Configure Battery Charge Thresholds

There are two battery charge thresholds. The first is START_CHARGE_THRESH this threshold contains the battery charge level below which charging will begin. STOP_CHARGE_TRESH is the second threshold. It describes up to which level the battery will be charged. Battery charge thresholds are used to limit the charging of the battery to extend the battery life.

Thresholds can be set in the file /etc/tlp.conf. Search and edit the following lines according to your needs.

START_CHARGE_THRESH_BAT0=75
STOP_CHARGE_THRESH_BAT0=80

This can also be achieved by using tp-battery-mode
