At the top of the report you'll find some general information about the computer
At the top of the report, as shown in Figure C, is some general information about the computer that includes the name assigned to the system, the brand and model of the device, the BIOS version and date, and the operating system build number. It will then list an item called Platform Role, which as you can see is identified as Mobile for this laptop. The next item in this section is called Connected Standby and you can see that for this particular laptop it is listed as Not Supported. This is followed by the date and time that the report was run.
When you run the Battery Report on a Surface RT or similar device, you'll see that the Platform Role is listed as a Slate. You'll also see that Connected Standby is listed as Supported.
One of the big benefits ARM-based devices is that they can last days or weeks on a single battery charge. When Microsoft was creating Windows RT they wanted it to have the best possible battery usage for a WOA (Windows On ARM) and developed a new power mode technology called Connected Standby.
Essentially, Connected Standby allows a Windows RT device to conserve battery power by entering a very low power mode when the device is not in use, but remain connected to the network. The goal is to allow the system to conserve battery power while still allowing a Live Tile on the Start Screen to maintain connectivity to its source. For example, a news or weather app can maintain its connection such that when you wake up a Windows RT device, the information displayed in the Live Tile will be as current as if the system was always on.
