power-profiles-daemon, the power mode settings backend in Gnome, released 0.20 today!
The new release added amdgpu panel power savings which uses dedicated hardware in systems with integrated Radeon graphics to decrease panel power consumption when the system is on battery.
This activates the DRM connector attribute panel_power_savings which takes a range from 0 to 4 to indicate how aggressively to enable panel power savings.

TLP is an advanced power management tool for Linux. Here’s how to install the latest 1.0 release in Ubuntu 14.04, Ubuntu 16.04, Ubuntu 17.10, and derivatives via PPA.
TLP is a command line tool with automated background tasks. It comes with a default configuration (/etc/default/tlp) already optimized for battery life, so you may just install and forget it. Nevertheless TLP is highly customizable to fulfil your specific requirements.
While Ubuntu Software only provide an old version, you can always install the latest TLP from its official PPA. So far Ubuntu 14.04, Ubuntu 16.04, Ubuntu 17.04, and Ubuntu 17.10 are supported.
1. Open terminal either via Ctrl+Alt+T shortcuts or by searching for ‘terminal’ from app launcher. When it opens, run command:
sudo add-apt-repository ppa:linrunner/tlp
Input your password (no visual feedback) when it prompts and hit enter
2. If you’ve installed an old version for Ubuntu Software, launch Software Updater to upgrade it.
or simply run following commands one by one to install (or upgrade) TLP:
sudo apt-get update sudo apt-get install tlp
Once installed, TLP runs silently as background tasks. You may change the default settings by editing /etc/default/tlp, or use command line tools to specify your requirement. Read the full documentation.
To remove tlp, open terminal and run command:
sudo apt-get remove --autoremove tlp
To remove the PPA, launch Software & Updates and navigate to ‘Other Software’ tab.
