Introduction

Energy Star X leverages Windows 11's EcoQoS API (aka "Efficiency Mode") to throttle background applications to improve battery life and system thermal. It will not throttle foreground application to ensure user experience.

This app is a GUI version of the open source software EnergyStar, developed with Windows App SDK (WinUI 3).

Requirements

For the best result, you need:

Software

  • Windows 11 22H2 (Build 22621) or above

Hardware

  • Intel 10th gen or newer mobile processors
  • AMD Ryzen 5000 or newer mobile processors
  • Qualcomm mobile processors

This app can work on Windows 11 21H2 (Build 22000) and older hardware, but may not get the best result.

Usage

Let it run in background in the system tray. You can choose to run it automatically at startup in settings page.

You can see a green leaf icon next to throttled background process in Task Manager's "Status" column.

Known Limitations

  • If you are using mouse-related software such as Logi Options+, your mouse cursor may lag while moving. Please add these softwares to the whitelist.
  • If you are using some taskbar enhancement software such as StartAllBack, this app may crash when you hover over system tray icon.
  • Child processes do not get boosted when the parent process receives input focus.
  • System processes (which is Session 0) do not get throttled. Currently there are some assumption that non-user processes know what they are doing.
