Expert Reviews

What experts liked

Asus claims the ZenBook 13 UX331UN is currently the world's thinnest laptop with discrete graphics.
Open up the ZenBook and you’re presented with a smart matte chassis that feels far more sturdy. The edges are lined with a generous number of ports, considering the slim finish.
The ZenBook 13 and its quad-core, eighth-generation CPU clears the 3,000 mark with ease, along with its similarly equipped competition.
Powerful processor
Fantastic web browsing battery life
The ZenBook UX331UA gets a fantastic screen. Our review unit sports a full HD 1920×1080 resolution screen, which is vibrant and displays crisp images. It uses In-Plane Switching (IPS) panel technology, thus benefits from wide viewing angles (178 to be precise) and the Anti-Glare actually works as it should.
Battery life lasted 13.75 hours in a light load of web browsing tests, and 7.75 hours in a heavier load of 4K video playback tests.
Your ZenBook will last a while on a charge. It ran for 9 hours and 11 minutes on the Laptop Mag Battery Test 2.0, which continuously browses websites, graphics tests and videos over Wi-Fi at 150 nits of brightness.
The Precision Touchpad has a satisfying travel and clicking noise when pressed. It was responsive and accurate, and we had no problems using it for two-finger and three-finger gestures or zooming in and out.
It's a LED backlit display with Anti-Glare panel. Features ASUS Splendid technology and WideView technology
Note that the display offers a special provision to protect your eyes; complete backlighting and an anti-glare panel(60Hz)
The bezels around the display screen of this device are very thin. It is known as Nano-Edge Bezel Technology.

What experts didn't like

Another potential strike against it would be its USB-C port. It's USB 3.1 (gen 1) and not Thunderbolt 3, so data speeds and display support is more limited and it doesn't support charging the laptop, so you'll need to carry its little 65-watt power supply.
The biggest problem is that those dual speakers are housed on the underside of the device, so any output is muffled by the desk or your lap – or whatever the device is resting on. However, even if you lift the laptop, the sound is still weak. In a quiet environment, you’ll struggle to make out conversations in flicks and TV shows.
The ZenBook 13 isn’t a gaming machine, nor will it rattle any bones with it comes to processor-intensive tasks like video encoding.
Laptop lid is a fingerprint magnet
The only real problem with the UX331UA’s display is brightness. It maxed out at 256 nits in our reading, which is a bit under our preferred minimum of 300. Most competitors offer a brighter display.
Gaming performance is a shadowy foray for most Ultrabooks, since most lack dedicated graphic cards. The UX331UA’s gaming capabilities are limited but you can get away with basic games played at low-medium settings.
There's no optical drive like a CD or DVD reader, so you'll have to buy an external drive if you need one.
Slower than average transfer speeds
Lack of Thunderbolt 3 ports are the main reasons the ZenBook 13 isn’t our top pick
Not good for Pro-gaming


The days of being stuck at a desk all day are history. Today, you can work from your home, an office or a beachfront vacation home. But to do that, you need a powerful, yet portable laptop. A laptop with a battery that can go for hours on a charge, while also letting you stream the latest season of “Stranger Things” while you scroll through your social media feed.

The good news is, laptops are becoming more lightweight and powerful each year. You no longer have to pay a fortune for a laptop that will handle everything you need to do, whether you’re a college student or a high-powered executive. Newer laptops are both affordable and robust, giving you a wide range of options for your budget.

But with the latest round of laptop models, peripheral support is a huge factor. As consumers have embraced streaming, manufacturers have done away with DVD-ROM drives. But now that streamlining also applies to USB ports, with many newer models coming only with two or three. As the market moves toward USB-C charging, you may also find you need connectors for each of the ports you don’t plan to use for your power cord.

Storage is another consideration when you’re choosing a computer. Yes, the cloud has made this less important, but you’ll still want plenty of space for all the applications and documents you’ll need to store. If you decide to download a few Netflix movies to watch on long flights, you’ll need at least 280 megabytes per hour of standard-definition video. Over time, you’ll also find operating system upgrades and software updates take up an increasing amount of hard drive space. All of that combined simply means that the more storage you invest in upfront, the less likely you are to need a new computer in a few years.

Thanks to the app ecosystem, consumers have a wider range of options in the devices they use for work and play. This means you can buy an affordable laptop and rely on the power of the cloud for everything you need. This has also made it easier for manufacturers to create laptops that are inexpensive, making them accessible to a wider consumer market. But there are so many affordable laptops now available, it can be difficult to choose one. Fortunately, by looking at your own budget and listing the features you feel are most important, you can narrow down the options.
