Performance, Battery Life, and Conclusions
Since we haven't taken a look at a lot of low-end Windows tablets, we decided to compare the Android version of this tablet to other similar tablets we've reviewed.
Taking a look at some general performance and GPU benchmarks, it's clear that you should not be buying the Yoga Book for its stellar computing capabilities. Performance is right in line from the Dell Venue 8 7000, which came out in early 2015, and is completely outclassed by modern Android handsets such as the Mate 9.
We see a more competitive story when we look at graphics performance. The Intel HD 400 graphics in the Yoga Book manage to compete well with, and sometimes best the Mali-T880 graphics in the Kirin 950 found in the Mate 8.
While performance isn't necessarily a strong suit of the Yoga Book, battery life is a different story.
Running our web browsing battery test on the Windows Yoga Book with a screen brightness of 180 Nits, we were able to achieve a runtime of 9 hours and 3 minutes. This is incredible for a device with a 32 Wh battery. When compared to full-fledged notebooks like the Dell XPS (2016) at just under 8 hours of battery life, it is quite impressive to have a machine as small as the Yoga Book, running full Windows that you can throw in your bag and not worry about the battery life of.
Adding in the unique input methods and the challenges they can present to the device makes the Yoga Book a hard sell for a lot of users.
However, I do think the Yoga Book makes sense for a certain segment of users. With a great stylus, long battery life, and a super portable form factor, the Yoga Book could be a great machine for artists or avid note takers to carry everywhere with them. With the lack of a major price difference, I would recommend the Windows version of the Yoga book, due to the more robust app ecosystem of desktop Windows applications.
Overall, I hope that Lenovo doesn't abandon this concept and continues to use the Yoga brand to innovate in the often stagnant PC arena, but for most of our readers this device just isn't a great fit.
