The 2026 HP OmniBook 3 is a budget Windows on Arm laptop that focuses on value—light weight, a vibrant 2K OLED screen, and an eye-popping 28 hours of battery life—while still carrying the usual tradeoffs around speaker quality and app compatibility.
For days when you just want your laptop to *last*, the 2026 HP OmniBook 3 makes a strong first impression. In testing, it ran for an astonishing 28 hours on a single charge—an endurance stretch that beat the previously longest-lasting laptop the reviewer had tested, the 2025 HP OmniBook 5.
It’s the kind of battery performance that changes how you plan your day. Instead of checking the remaining charge, you start moving through work the way you would with a device that doesn’t force you to think about power.
HP positions the OmniBook 3 as a low-cost everyday Windows PC for school, office work, and remote work. It’s also built for travel, with a sleek design that measures 14.12 x 9.91 x 0.58 inches and weighs just under four pounds.
The unit reviewed came in Glacial Silver, with a slightly darker gray keyboard. The keys use rubber-capped key design. and the reviewer usually dislikes that “mushy” feel—but said the OmniBook 3 doesn’t fall into that trap. The keys have a decent travel distance, making typing comfortable during long workdays.
HP enlarged the trackpad compared to the previous generation, giving more room for hand gestures and smoother cursor control. The trackpad sits slightly off-center. which the reviewer found leads to a more natural hand position. since more of the right hand can rest comfortably on the wrist rest. HP also rounded off the edges of the wrist rest so there aren’t sharp edges pressing into the wrist.
The screen is where the “value” pitch gets real. The OmniBook 3 uses a 2K OLED panel that covers the entire DCI-P3 color gamut for accurate color reproduction. It claims a 1,000,000:1 contrast ratio aimed at deep blacks and rich reds, blues, and greens. The display also supports 10-bit color depth for smoother gradients and more natural color transitions. and it includes Eye Ease technology intended to reduce harmful blue light.
There’s also a practical design change: HP moved the aspect ratio from 16:9 (as seen in older models) to 16:10. The reviewer described that extra space as roomier for work, while shrinking the bezels for a cleaner look. One notable omission is touch—there’s no touchscreen option. The reviewer called that a benefit, saying touchscreens on traditional clamshell laptops can feel gimmicky rather than useful.
Still, the screen has a clear weak point. Brightness tops out at just 300 nits. Indoors it looks fine, but in bright lighting or outdoors, screen visibility drops.
Audio is another downside. Speakers are placed at the bottom of the chassis, and the reviewer found the output muffled. They noted that some manufacturers counter bottom-firing speakers with audio-boosting software or advanced tuning. but said HP didn’t do that here. As a result, multimedia sound is flat and lacks immersion. The webcam lands in the “gets the job done” category too: color balance looks natural with no weird tinting or blown-out exposure. but the Full HD IR lens lacks the sharpness found on more premium laptops.
Under the hood. the reviewed configuration includes a Qualcomm Snapdragon X X1-26-100 processor. 16GB of DDR5 RAM. and a 512GB SSD. The Snapdragon X isn’t described as a powerhouse chip, so the OmniBook 3 lands in the midrange category. In performance tests and day-to-day use, most applications ran without major problems. Office work felt fast, web browsing was snappy, and multimedia streaming worked without issue.
But the reviewer also flagged a limitation that comes with being a relatively new Windows on Arm chip. Certain programs may not work due to compatibility issues. They tried the Google Play Games beta app to test mobile games as well as benchmarks like 3DMark—and neither worked.
The reviewer downplayed it as a minor problem: most mainstream apps still work, and compatibility problems are most likely if you specifically hunt for incompatible software or beta programs. They also pointed out that developers generally keep their apps updated.
There’s a table of benchmarks comparing the OmniBook 3 with other models in its class, and the takeaway is straightforward: the 2026 OmniBook 3 isn’t described as a major step forward over older laptops—it keeps in line with the others.
Even with those tradeoffs, the OmniBook 3’s price and battery performance are doing the heavy lifting. The 2026 HP OmniBook 3 is listed as available on Amazon for around $539, while Walmart has it on sale for roughly $505. At a time when even basic laptops are said to be super expensive. the reviewer described it as refreshing to see a machine with lightweight portability. a vibrant 2K OLED display. and the best battery life they’ve ever experienced on a notebook.
HP says the OmniBook 3 is available in five different colors. The review unit is Glacial Silver, while Amazon and Walmart currently appear to be selling the Mica Silver version, described as a darker gray—almost black.
