Microsoft Teases Multi-Day Battery Life For Upcoming ARM-Powered Windows Devices (techspot.com)

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."

Re:It’s multi-day battery life as long as it

I was wondering why this would be different from the Surface RT, and after reading TFA I still don't know.
Also, who are they going to sell these to? The people who bought Surface RT won't want to be fooled again (presumably) and everyone else already has an iPad or some sort of Android tablet, or maybe a Microsoft Surface device which runs x86 and so has access to whatever Windows software the user might need.
This looks like all the other Microsoft "new market" type efforts. Doomed to failure and then irrelevance, then death.

I highly doubt it will get days of battery life in any realistic scenario.

There is no magical way to make common tasks 2-3x more efficient. There are no magic RAM chips that draw 25% normal power, no special GPUs that decode video using half as much energy as every other one. Did someone invent a super efficient LED backlight?

And people expect their Windows devices to stay connected to networks and more active than a phone, so that Skype calls can come in etc. Android and iOS sleep for to to 15 minutes, with no IP connectivity and delayed notifications, to save power.
