Information about Surface Pro it continues to expand since yesterday and the latest data we have is not very promising. As reported from Microsoft, battery of the new tablet will have a autonomy approximately 4h. The team will undoubtedly have Technical specifications very powerful that bring it closer as a device to laptops than tablets, and that affects battery consumption, of course, but it is still a really poor data for what, after all, it is supposed to be a mobile device.
Yesterday we inform you that Microsoft had finally released the price of Surface Pro which, without great surprises, will be quite high: $900 for the model with 64 GB storage capacity, and $1.000 for the one of 128 GB. The technical specifications are far superior to those of Surface RT And it certainly seems to better represent the concept of a tablet-laptop hybrid that Redmond's are trying to achieve. However, it seems that the best features of the device are going to have a price, in addition to the economic one, which is none other than its limited autonomy.

As reported in The Next Web, last night on the official Twitter account of Microsoft A user's question was answered advising that we could expect the duration of the battery of Surface Pro out about half of the of Surface RT, and we already know that the autonomy of this is around 8h (as always, depending on the use that is given), so it seems that we should not expect it to exceed the 4h if we make more or less intense use of it.
The data would be quite positive if we were talking about a laptop, but it is certainly daunting for a tablet, given that the autonomy is a fundamental characteristic of every mobile device (think, for example, of the pride with which Apple has always talked about the more than 10h video playback that allows your iPad), so much so that one wonders to what extent it is Surface Pro a tablet and to what extent it can be aimed at users of this type of device. We will have to wait, as always, to see how it is received once it reaches the market.
