Microsoft announced several new features for its Edge browser this week. Most of those tools focus on saving time and money while shopping, such as the new price notification feature. The company also introduced efficiency mode for Microsoft Edge to reduce battery consumption.
Efficiency mode kicks in when a PC's battery is low. The feature reduces CPU and RAM usage to lower how much power it draws from a device.
Here's Microsoft's description of the feature from the blog post introducing it:
When your device's battery is low, Microsoft Edge will set itself to efficiency mode and significantly reduce system resource usage like CPU and RAM, extending battery life and helping you get more done while on the go.
If you don't like Edge switching to efficiency mode, you'll be able to toggle the option off through the browser's settings.
The feature initially rolled out with Edge version 95 in October but was highlighted by Microsoft's recent blog post.
