[Software] Save battery power on laptops

With TLP I was able to extend the battery life of my ThinkPad E595 significantly.

“TLP is a feature-rich command line utility for Linux, saving laptop battery power without the need to delve deeper into technical details.”

If you prefer tools with UI, check TLPUI: https://github.com/d4nj1/TLPUI
There is also a repository for it:

sudo add-apt-repository ppa:linuxuprising/apps
sudo apt update
sudo apt install tlpui

When using a ThinkPad, there are specific kernel modules that can be installed.

Check with tlp-stat -b

Install with:

sudo apt install acpi-call-dkms tp-smapi-dkms

Another tool to monitor your power usage is PowerTOP:
