How long does the Surface Book in tablet mode?
Of all the products, which were presented at a recent press conference, Microsoft, the greatest public interest was aroused by an innovative notebook Surface Book with a 13.5-inch screen. Actually this is the first laptop in the history of the company, but it is much more than just a laptop.
Many Microsoft fans were quick to call it a «MacBook killer» and the reasons for such determination certainly is. Surface Book became the most powerful device among 13-inch laptops/hybrids that will be released before the end of this year.
Being ultraportable, super thin and light, it is equipped with the new Intel Skylake from the sixth generation (Core i5 or i7), dedicated graphics from NVIDIA, up to 16GB RAM and SSD-drive capacity up to 1 TB. All this makes him a true champion among ultrabooks.
A particularly interesting solution is the unique hinge design (in many respects similar to the one that offers the Yoga 3 Pro from Lenovo) between the display Surface Book with a main body of the device. This design provides additional flexibility for positioning the display, which in turn provides maximum convenience when working. Moreover, one pressing a special button you can separate the screen and keyboard to work in tablet mode. It would seem that the best of both worlds in one device. But anyway, the Surface Book will not be able to replace a tablet for one simple reason: battery life.
On the specification page Surface Book on the official Microsoft site says about 12 hours of battery life in video playback mode, but here we are talking about scenarios when the device is fully assembled; how about a tablet?
The main battery Surface Book placed in the keyboard, while the battery is in the housing of the display is an auxiliary, and therefore has a smaller capacity. The ratio between them is approximately 3:1, that is, when using a device separate from the keyboard, you can expect about three hours without recharging.
Doesn’t sound like much if you compare with the new Surface Pro 4, which promises up to 9 hours, but we have to keep in mind the purpose of the Surface Book. It’s hard to imagine-who is going to buy it to use as a tablet. Of course, many will find use for it as such, but the vast majority of the time users will benefit from the main battery by connecting the display with the keyboard.
