ASUS Zenbook UX305UA-AS51: A Powerful Combination of Beauty and Power

We are drawn to what is attractive and powerful, and those are the very two features offered by the ASUS Zenbook UX305UA-AS51. Users are veering away from bulky portables and are looking for slimmer options that don’t skimp on features and performance either.

This is unlike the Lenovo LaVie Z HZ550 which opted to use super-thin materials to keep their devices thin and slim but ultimately, the build quality was sacrificed.

Measuring 0.6 by 12.8 by 8.9 inches (HWD), the Zenbook UX305UA is a lightweight device weighing 2.8 pounds, making it easy to carry around wherever you need to use it. For comparison, the MacBook Air 13-inch measures 0.68 by 12.8 by 8.94 inches and weighs 2.96 pounds which means it’s a bit thicker and heavier.


Powered by a sixth-generation 2.3GHz Intel Core i5 processor, the UX305UA is capable of delivering better performance and energy efficiency than the Broadwell CPUs that preceded it. It’s for this reason that Skylake processors have been picked for use in hybrids, laptops and desktops. These kinds of processors not only provide a good performance, they are designed for ultraportability with a focus on mobility.

The Zenbook UX305UA-AS51 obviously performs better than its predecessors that used the older Core i5 processor. It can also deliver solid multimedia performance than the other units in its class, however, it performed behind Lenovo Yoga 900 and the Dell XPS 13 Touch (these are more expensive systems that have the Core i5 processor).

The display features a full HD resolution and an In-Plane Switching panel that provides wide viewing angles and good color. Reflections are kept to a minimum thanks to an anti-glare finish, but it does dull the blacks on the screen. The display doesn’t have touch capability, however, and it’s something that might limit the attraction factor for those who want a touch interface.

Just like other Zenbooks, the chiclet-style keyboard is great to type on. However, it doesn’t have a backlight which might deter those who prefer to work with the lights out or are giving a presentation. The touchpad which measures 4.1 by 2.9 inches and features a wide, clickable surface.

This is better than the Dell XPS 13 Touch which clocked in at 7 hours 40 minutes while lesser than the Lenovo Yoga 900 which can run for 10 hours and 56 minutes. However, the laptop that bests it all is the Apple MacBook Air 13-inch which has a battery life of 17 hours and 36 minutes.


The integrated HD graphics on the Asus Zenbook UX305UA-AS51 is typical in those found in other midrange ultraportables. As such, it won’t do as well for 3D gaming but will do perfectly find for everything else. With a Skylake CPU and dual-channel RAM, the performance of the UX305UA is similar to other mid-range graphics cards. Although the UX305UA has limited gaming capabilities, it can play games that don’t burden the hardware as much.
