Improve Microsoft Edge power consumption and performance by enabling Efficiency mode
Microsoft Edge users who use the browser on mobile or low-performance devices can enable efficiency mode to improve browser performance.
Previously called Performance Mode, Efficiency Mode is available as an option under System and Performance in Edge Settings. The main idea behind Efficiency Mode isn’t new: to sleep tabs that haven’t been used for a while to free up memory and reduce CPU usage.
You can find performance options under edge://settings/system in Microsoft Edge for Windows, Mac OS, and Linux. Users who prefer to use the menu can also select Menu > Settings > System and performance to access it.
Efficiency mode can be enabled or disabled, the default seems to be disabled in most configurations. Microsoft says on a support page that efficiency mode can be turned on automatically if a mobile device enters battery saving mode in Windows. A blue pulse icon in the Microsoft Edge toolbar indicates this. On Mac OS X devices, efficiency mode automatically turns on if the battery power state reaches 20%. On Linux, efficiency mode is disabled by default.
Once activated, Edge will put inactive tabs to sleep for 5 minutes to free up system resources. Microsoft notes that benefits vary as they depend on factors such as device used, number of tabs open, and other factors. The feature can be beneficial for mobile devices but also for desktop devices as it can also improve performance.
Efficiency mode is designed to help extend battery life. It minimizes power consumption by reducing resource usage (CPU usage) by changing some tab activities on tabs you don’t interact with and by putting inactive background tabs to sleep after 5 minutes or less.
Efficiency Mode comes with a number of preferences that users can tweak to customize functionality. In fact, all settings can be changed even if efficiency mode is not activated.
- Save resources with sleep tabs — The function unloads inactive tabs to free up memory and improve performance.
- Molten sleeping tabs — All sleep tabs are shown faded for better identification-
- Put inactive tabs to sleep after specified time — 5 minutes by default and fixed to this period if the efficiency mode is activated. When efficiency mode is disabled, other periods can be selected.
- Never put these sites to sleep — Add sites to the exclusion list so they are never put to sleep by Edge.
Efficiency mode can improve battery life and performance for devices running Microsoft Edge. Mobile devices on battery power and low performance devices may see the greatest improvements with the mode enabled.
Now you: do you configure your browsers to hibernate inactive tabs?
