Microsoft has rolled out a number of new features to Insiders that are expected to become part of its Redstone 3 update, out towards later this year - including a feature that will automatically throttle background apps in order to save power.
Battery life is something that Microsoft takes very seriously indeed, as anyone who has ever tried to switch their default browser from Edge will know, thanks to the nagging it generates.
Now, Build 16176 of Windows 10, which has been made available to Insiders on the Fast Ring, has new technology that will automatically throttle background apps, and therefore reducing the power outlay of the machine and increasing battery life of portable devices by up to 11 per cent.
This may not sound like a lot but it's 48 minutes on an eight-hour model, and it all adds up.
"Most people running Windows like having multiple apps running at the same time - and often, what's running in the background can drain your battery," explained the Microsoft blog.
It continued: "In this latest Insider Preview build (Build 16176), we leveraged modern silicon capabilities to run background work in a power-efficient manner, thereby enhancing battery life significantly while still giving users access to powerful multitasking capabilities of Windows.
"With 'Power Throttling', when background work is running, Windows places the CPU in its most energy efficient operating modes - work gets done, but the minimal possible battery is spent on that work."
Microsoft isn't committing to a total power saving, saying only that "this capability should help many of you see a nice boost in battery life!".
The app also lets you override certain apps that you don't want throttled. It will work initially on Intel Core 6th Generation and better, with promises of further expansion of the feature as its worked on.
The company has also confirmed there will be APIs available for developers whose apps need retooling (ie: get borked) by the new feature.
