🔋 Improve your Windows 11 device's battery life.

Energy Star X is a power management tool designed to optimize battery life and thermal performance on Windows 11 devices by leveraging the EcoQoS API. This software ensures that background applications are throttled to extend battery life while maintaining smooth operation of foreground tasks, thus preserving user experience.

Key Features:

  • EcoQoS Integration: Automatically manages resource allocation for background processes to improve energy efficiency without affecting active applications.
  • User-Friendly GUI: Built with WinUI 3, Energy Star X provides an intuitive interface for users to monitor and customize power-saving settings.
  • Compatibility Support: Works best on Windows 11 (22H2 or later) and modern Intel, AMD Ryzen, and Qualcomm mobile processors.
  • Customization Options: Users can whitelist specific applications to prevent performance issues with mouse-related software or taskbar enhancements.
  • Background Operation: Runs in the system tray for seamless integration, with optional startup automation.

    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.
