An anonymous reader quotes a report from TechSpot: Microsoft late last year announced a partnership with Qualcomm to bring the full Windows 10 experience to ARM-powered devices. Terry Myerson, Executive Vice President of Microsoft's Windows and Devices Group, promised at the time that Snapdragon-powered Windows 10 devices would be efficient in the power consumption department. We're still waiting for the partnership to bear fruit but in the interim, new details regarding efficiency (and a few other subjects) have emerged. With regard to battery life, Pete Bernard, Principal Group Program Manager for Connectivity Partners at Microsoft, said that to be frank, battery life at this point is beyond their expectations: ""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."
