Microsoft claims Windows 10 ARM battery life will be a ‘game-changer’ for laptops - The Verge

Meanwhile in the waning Wintel world: Microsoft’s Surface Book 2 claims 70% more battery life than MacBook Pros, 45% more pixels (9to5Mac)

"Microsoft first unveiled its plans for ARM-powered Windows laptops last year. The new devices will be powered by Qualcomm’s Snapdragon 835 processor, and will support traditional desktop apps thanks to an emulator in Windows 10. While Qualcomm previously promised laptops before the end of the year, we haven’t heard much about them yet. Asus, HP, and Lenovo are all preparing devices, and it seems like battery life will be a key selling point.

During a Qualcomm summit in Hong Kong this week, Microsoft and Qualcomm dropped some hints at what to expect from new ARM-powered laptops. Trusted Reviews reports that Qualcomm is still committed to getting devices in the market in December, and that Microsoft is promising multi-day battery life. “To be frank, it’s actually beyond our expectations,” says Pete Bernard, a program manager at Microsoft. “We set a high bar for [our developers], and we’re now beyond that. It’s the kind of battery life where I use it on a daily basis. I don’t take my charger with me. I may charge it every couple of days or so. It’s that kind of battery life.”"
