Samsung Galaxy Book4 Edge 14 review: a stunning screen that travels light

A premium 14-inch screen and body for everyday Windows work

This review covers the US Samsung Galaxy Book4 Edge 14, model NP940XMA-KB1US in Sapphire Blue, with Qualcomm's Snapdragon X Elite X1E-80-100, 16GB of memory, 512GB of storage and Windows 11 Home. Samsung released it in June 2024 as its first Copilot+ PC.

There is a newer model, the Samsung Galaxy Book6 Edge, which we review separately. It is a 16-inch laptop, so it follows the Book4 Edge without replacing this size, and we compare the two further down. For a 14-inch Galaxy Book Edge, the Book4 is the model to judge.

This is full Windows 11 running on a different kind of processor. The Snapdragon chip uses Arm architecture, the design family behind most phone chips, rather than the Intel and AMD designs most Windows software grew up on. For most buyers that difference stays in the background, but app and accessory support deserve a quick check before purchase, which our compatibility section walks through.

Samsung's original $1,349.99 starting price has no bearing on today's choice; what matters is what else the same money buys now. Match memory and storage first, then compare screen quality, weight and noise, and only then ask whether a newer processor would change anything you actually do. Paying extra for speed you won't use makes little sense, but an attractive laptop doesn't excuse a weak offer either. Our best Copilot+ laptops guide maps the wider field.

The display pays off most when you work on the move

The 14-inch AMOLED panel is the main attraction. Its high resolution keeps small text crisp, the 16:10 shape shows more of a page than a widescreen panel, the 120Hz variable refresh rate makes scrolling fluid, and touch makes zooming into photos or tapping through slides natural on a laptop this size.

Independent measurement supports the premium billing. CHIP recorded roughly 405 nits in standard use and 545 nits on a full-white HDR image, with full sRGB and DCI-P3 coverage. Coverage means the panel can reach those colors, not that every shade is accurate, so paid photo work still calls for calibration. For movies, photos and everyday work, OLED contrast at that brightness is a clear step up from typical budget LCDs.

Glare is the trade-off to weigh. Samsung adds anti-reflective cover glass and a Vision Booster brightness feature, but this is still a glossy touchscreen. Reflections are reduced, not removed, so anyone who routinely works facing a window or outdoors may be happier with a matte screen, even a less impressive one.

How you use the screen decides how much all this is worth. If the laptop spends most days closed on a desk and connected to a monitor, its best feature contributes little, and a cheaper or roomier machine may serve you just as well. If it opens on trains, in lecture halls, at client sites and on flights, the display is working for you for hours every week. At 14 inches it is a compact canvas: fine for a document beside a browser, cramped for side-by-side work all day.

Keep the kit small and this laptop stays easy to carry

Ports are few but modern: two USB4 ports, HDMI and a headphone jack, with no USB-A or microSD. The USB-C charger occupies one of those USB4 ports at a desk, leaving a single high-speed port for everything else.

The setup is most convincing when it stays simple. A Bluetooth mouse, documents that fit on the laptop and an HDMI monitor need nothing extra. A workflow built around a card reader, a portable drive and several dongles is different: the laptop is still light, but grabbing it and going turns into packing a pouch, and some of the convenience you chose a compact laptop for slips away. Decide which kind of user you are before weighing this design against a model with more built-in ports.

CHIP found the backlit keyboard shallow, with light feedback, while praising the roomy, roughly 12 x 8 cm touchpad and rating the quad speakers as good, with some rattle on heavy bass. That points to a laptop better suited to email, notes and editing than to long writing sessions for people who prefer a deeper keystroke. CHIP also found the laptop quiet even under load. Sign-in uses a fingerprint reader built into the power button.

Samsung's device-linking features add convenience, each with its own requirements. Quick Share moves files between compatible devices, Auto Switch moves compatible Galaxy Buds between devices, and a supported Galaxy phone can serve as the laptop's webcam. Microsoft's Phone Link works with compatible phones and accounts and is not unique to Samsung. Check your own phone and earbuds against each feature before counting any of them as a reason to buy.

Battery life: strong on light days, shorter at high brightness

Set expectations by this laptop's own results. The 14-inch model pairs a 55.9Wh battery with a high-resolution OLED screen, and neither the runtime claim Samsung made for the 16-inch Book4 Edge at launch nor 16-inch test results describe this model's endurance.

Two independent labs tested equivalent 14-inch configurations in 2024, using different methods. In the default Optimized mode, Notebookcheck measured just under nine hours of Wi-Fi web browsing at 150 nits, about six hours and 45 minutes at maximum brightness and nearly 14 hours of local 1080p video. CHIP recorded just under seven hours in PCMark 10's office workload, nearly 10 hours in an intensive web test and a little over 11 hours of Full HD video at 200 nits. Because the protocols differ, the figures belong side by side, not averaged.

Read by workload, the picture is clear enough. Lightweight daily use, meaning browsing, documents and email at moderate brightness, is where this laptop does well, and we would expect it to cover a light workday, though not one that stretches into a long evening. Brightness is one important variable you control: in Notebookcheck's identical browsing test, maximum brightness cost more than two hours. Mixed office workloads landed lower than simple browsing, and local video was the best case, which suits flights.

Your schedule should decide whether the charger comes along. On call-heavy days, in bright rooms or for anything beyond light office work, pack the included 65W USB-C charger. For a shorter outing of documents and browsing at moderate brightness, leaving it behind is a reasonable bet.

RAM, storage and Windows on Arm: what to check before you buy

Memory and storage are fixed internal components. The 512GB uses eUFS, flash storage of the kind more common in phones, rather than an SSD you can swap later, so the capacity you buy is the capacity you keep.

Whether 512GB is enough depends on what you keep offline, not on which cloud service you use. A cloud label is not a storage plan: OneDrive or Google Drive can keep large folders fully downloaded, and those count against internal space like any other file. Separate active work from archives. Documents, spreadsheets and a modest photo collection take little room; a growing camera library, offline video projects or large creative apps fill it faster. If your active files are large and still growing, a 1TB configuration (Samsung offered one at launch) or upgradeable storage makes more sense; if only your archives are large, a drive that stays at home may be all you need.

Memory is a separate question from file space. 16GB suits office multitasking, browser tabs and calls, while heavy creative projects, such as long video timelines, are what push it.

Software support is the other check. Many Windows apps run natively on Arm, and Windows' Prism emulation runs many traditional Intel and AMD programs, though Microsoft does not guarantee that every one will work. Hardware drivers are different: printers, scanners, audio interfaces, VPN clients and security tools need an Arm64 driver or a compatible one supplied by Windows, and emulation cannot translate drivers.

Make the check specific. List the apps, accessories and work tools you cannot do without, then confirm Arm support with each vendor or your IT department. If one essential item fails, the Galaxy Book4 Pro 14 comparison below is your next stop.
