Since the Yoga 13 uses typical Ivy Bridge class components (17W dual cores, HD4000 graphics and SSD) from Intel's strict Ultrabook definition, we were not too surprised to see run of the mill benchmark scores from the system.

The Powermark Professional Edition benchmark gives a more in-depth look into the capabilities of the hardware in terms of battery life.
Under a moderate load (web browsing, word processing, some video watching), the Yoga was expected to last a total of 4 hours 6 minutes. This is not a shabby score by any means, but there are many Ultrabooks out there capable of lasting up to 6 hours (such as the Samsung Series 9 Ultra and the Dell XPS 14). The battery is sealed, so no luck with any DIY removal, but again, this is part and parcel of most Ultrabook designs.
Display wise,the 13" 1600×900 IPS panel produced a maximum brightness of 289cd/m2 and 70% of the sRGB colour space which is better than most bog standard 1366×768 TN screens, but behind the excellent full HD offerings found on the Asus Zenbook Prime and the Acer Aspire S7.
