I recently moved from Windows to Ubuntu and I really loved the way Windows elongates by battery with Battery Saver.

On Ubuntu, my battery lasts halve the time it does on Windows and this is affecting my productivity.

In Ubuntu , you need to install TLP ( Linux Advanced Power Management Tool) to extends your battery life

By Default Ubuntu will eat more battery than windows OS

Add the TLP-PPA to your package sources with the commands:

sudo add-apt-repository ppa:linrunner/tlp
sudo apt-get update

Package Install

Install the following packages:

  • tlp (PPA or universe) – Power saving
  • tlp-rdw (PPA or universe) – optional, Radio Device Wizard
  • tp-smapi-dkms (universe) – optional ThinkPad only, tp-smapi is needed for battery charge thresholds and ThinkPad specific status output of tlp-stat
  • acpi-call-dkms (PPA or universe) – optional ThinkPad only, acpi-call is needed for battery charge thresholds on Sandy Bridge and newer models (X220/T420, X230/T430 et al.)

The above packages may be installed via package management tools (Ubuntu Software Center, Synaptic, …) or terminal command:

sudo apt-get install tlp tlp-rdw

 

ThinkPads require an additional:

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

TLP will start automatically. To avoid having to restart the system, the first time you can start it manually by using the following command:

sudo tlp start
Check

Use the tlp-stat terminal command to check if TLP is working properly

sudo tlp-stat

and check the output
