This tutorial will show you how to turn on or off Efficiency mode in Microsoft Edge for your account or all users in Windows 10 and Windows 11.
The Microsoft Edge web browser is based on Chromium and was released on January 15, 2020. It is compatible with all supported versions of Windows, and macOS. With speed, performance, best in class compatibility for websites and extensions, and built-in privacy and security features, it's the only browser you'll ever need.
Efficiency mode is designed to help extend battery life. It minimizes power usage by reducing resource usage (CPU usage) through modifying certain tab activity on tabs you’re not interacting with and putting inactive background tabs to sleep after 5 minutes or less. Benefits may vary depending on your device, applications, and individual browser habits.
Efficiency mode will become active when your device is unplugged and will remain active until your device is connected to power or your laptop runs out of battery.
Although efficiency mode has advantages for battery-powered devices, it can also benefit desktop computers. Efficiency mode minimizes browser resource usage so the operating system can focus its resources on other running apps. However, if you enable efficiency mode, you may experience some visible slowdowns when you browse.
How it works
- Puts background tabs to sleep after 5 minutes of inactivity, if sleeping tabs is on
- May cause videos to be less smooth, animations to slow down when you're not interacting with the browser
- Balanced Savings is the option that we recommend. It helps extend your battery life by saving computer resources. When your device is unplugged, moderate steps are taken to save your battery. You should experience no or minor slowdowns when you browse. When your device reaches low battery and enters battery saver mode, additional steps are taken to save your battery. With these additional steps, you may experience some visible slowdowns when you browse. For example, it may cause videos to be less smooth. To indicate that these additional steps are being taken, a filled heart pulse icon will appear in your browser’s toolbar.
- Maximum Savings is a good option when you can’t be connected to power for an extended period and need to conserve more battery life. With this setting, a filled heart pulse icon will appear on the Edge toolbar for the entire time that you are unplugged, additional steps are taken to save your battery. The changes being made to your browser will be the same as when additional steps are taken in Balanced Savings while on low battery. You may experience some visible slowdowns when you browse.
