Lengthy battery life and a slim design make it the perfect on-the-go companion.

Plus, that OLED touchscreen shows off colors to their best advantage.

ASUS has done a fantastic job lately of creating extremely thin laptops with fantastic battery life and solid performance.

ASUS Zenbook 14 (UM3406HA) has a very slim build.

Here’s what I’ve discovered.

It also has extremely long battery life to keep up with over a full day’s use.

This review was made possible thanks to a review unit provided by ASUS.

The company did not see the contents of this review before publishing.

Even so, it sells for only $799.00 at Walmart, making it a true value buy.

There are two USB-C ports, a headphone jack, and an HDMI port on the laptop’s left side.(Image credit: Rebecca Spear / Windows Central)

As such, the only option is to get 16GB of RAM with 512GB SSD storage.

These are fair capacities for average work, school, or personal laptop needs.

Still, I didn’t feel limited when it came to plugging in accessories or a monitor.

It’s very easy to navigate this app and find the specific tools I’m looking for.

As is typical with OLED panels, the Zenbook 14 OLED screen displays a beautiful color range.

Contrast is amazing thanks to the pixels producing true black rather than grey.

This, in turn, makes colors stand out that much brighter and more distinctly.

However, as is typical with OLED screens, this one doesn’t get as bright as some others.

It’s all very responsive and does what I’d expect.

It’s more than capable of handling everyday office and school tasks.

It’s not a huge difference, but shows that the two are similar with different tradeoffs.

Both results are good, by the way, and show that these are powerful processors.

I used Cinebench R23 to evaluate CPU graphics rendering performance.

Still, it is reliable enough for average computer use.

Now, as for the AI-boosting NPU itself.

It might be that AMD firmware needs to be updated before the Polycon will work with this NPU.

I’ll check again later and will add this info if I can.

Overall, this really isn’t that warm.

ASUS Zenbook 14 UM3406HA color gamut results.

The ASUS Zenbook 14 (UM3406HA) display produced 100% of sRGB, 95% of AdobeRGB, and 100% of P3 in our colorimeter test.

I never had to worry about it scalding my lap while I sat working on my couch, either.

That might be overkill for some, but incredibly useful for others.

Either way, this makes it the longest-lasting battery of any laptop we’ve tested thus far.

Meanwhile, the touchpad is a good size and always responds accurately to my movements.
