Battery Life and Portability Index

Batter Life and Portability Index

The very premise of an Ultrabook revolves around how portable they are. One crucial aspect about portability it battery life and it plays a big part in determining an Ultrabook's worth. Each of the notebooks compared here have the same processor (with onboard graphics), but other components vary from model to model. There is no right or wrong configuration, because each one caters to different usage patterns. For example, increased battery capacity can give you a better battery life (if all other aspects remain constant), but normally, this is accompanied by a proportional gain in weight. As such, one would have to choose their priorities appropriately to get the best out of their intended notebook. In the case of the Toshiba Satellite U920t, because of the added weight of the touchscreen and its sliding mechanism brings, Toshiba opted to equip the notebook with a much smaller battery pack to keep the overall weight of the machine in check. It is however not lighter than the smaller convertible Ultrabook from Sony, the Vaio Duo 11 which tips the scale at just 1.3kg.

In our Powermark benchmark (ran with audio and brightness set to 50%, and all wireless communications turned off), the Satellite U920t managed to get a battery up-time of 181 minutes, which is pretty impressive for its smaller than usual battery capacity. This is most likely due to the lower power consumption of the machine, which is close to the ideal power consumption achieved by the Intel reference Ultrabook.

Portability Index

The Toshiba Satellite U920t is the lightest machine out of the machines we're pitting against. However as we established earlier, it has a smaller battery capacity, which directly impacts its battery life. In our portability index, the battery life, weight and dimensions of the mobile device come together to determine if it's worth your effort to lug the machine around.

Stacking the Toshiba convertible Ultrabook against the competition we've lined up, its portability index is on par with the Samsung Series 5 Ultra Touch notebook, but pales in comparison to Lenovo's Ideapad Yoga, as well as the Intel reference Ultrabook. In the end, its mobility is just about average.

The more compact Sony Vaio Duo 11 naturally fared a lot better with a ratio greater than 3.1 because of its light weight and compact dimensions. Normally, we wouldn't be comparing two devices of a different size, but given that they are targeted the same consumer group with not much physical difference in size, comparisons are inevitable and the question then arises if the larger sceen size of the U920t is of any use. Unfortunately for Toshiba, its non full HD screen is a setback.
