Rated 3 out of 5 by LALawyer Discharges too quickly, even in sleep mode
The battery sheet, an accessory, is a necessity if you don't have access to power throughout the day. The battery sheet can be charged separately of by itself. Its advertised the battery sheet doubles the battery life. The sheet comes with a place to put the rubber cap that must be removed to attach the battery. The battery sheet discharges at an even greater rate than the computer and even loses its charge in sleep mode. The sheet is thought out and does discharge first so that if you need to remove it you would still have a full charge on the computer. The sheet though light, does make the unit bulky and heavier.
The computer is less than 3 pounds without and just over 3 with the battery sheet.

Rated 5 out of 5 by JorjXMcKie How much does this optional battery weigh?
This feature is a big reason why I chose the Sony Duo 11 over the Surface Pro. I didn't see the weight listed in product specs. Anyone know?
