Power Nap-like functionality, up to 13 hours HD playback
Windows RT PCs will have a feature similar to the Power Nap feature seen in some Apple notebooks, giving them up to 17 days of connected standby. This according to a post on the Building Windows 8 blog. The post details a number of performance, reliability, and battery features consumers can expect in the new line of devices due out from Microsoft and its manufacturing partners.
The post makes sure to note that any feature measurements are based on firmware that is still undergoing optimization. Also, Microsoft's measurements are given in the form of measurements, with results varying according to PC form factors and battery sizes.
The connected standby mode allows Windows RT PCs to move into a low-power mode, allowing it to maintain data currentness without drawing heavily on the battery. So far in Microsoft's testing, Windows RT machines get between 320 and 409 hours (13.3 to 17 days) of connected standby. With regard to video, the machines get between eight and 13 hours of HD playback.
The post also details the physical characteristics of the first wave of Windows RT devices. Windows RT machines will come in a range of form factors, ranging between 520 and 1200g, measuring between 263 and 298mm in length, 168.5 and 204mm in width, and 8.35 and 15.6mm in height.
Windows RT and a range of devices running the operating system will launch in October of this year alongside Windows 8. While Windows RT devices will likely see some benefits due to their reliance upon lower-power chipsets, they will at least initially lack some features that will be available in full on the non-ARM version of Windows, such as a full version of Office.
