Sony Vaio Duo 11 - Blurring the Line Between Tablet and Notebook
Battery Life & Portability Index
Battery Life
Battery life on the Duo 11 was about 10% under average at 165 minutes in our Powermark based balanced battery benchmark. This is likely due to its higher clock speed of the Core i7 processor which, as we saw from our previous page, gave it about 10% more performance on non-graphics related tasks. We suspect that the lower specced Core i5 model would be more inline with Toshiba's U920t, lasting roughly 180 minutes. The battery itself is non-removable. Despite the difference in specs, actual power consumption turned out to be quite good at slightly under average despite its full HD display. The power consumption of the Core i5 edition can only bet better, and that's a good thing.

Portability Index
Our Portability Index factors in battery life, weight and volume so you can see which notebook is the most worthwhile to carry around. As an 11-inch model, the Duo 11 obviously has a clear advantage over our other test models. But if portability is a concern to you, you definitely can't go wrong with the Duo 11.
