The Samsung Galaxy Book2 15 is decked out in a sober anthracite gray dress, simply embellished with a shiny logo on the hood. However, the coating tends to easily retain fingerprints and quickly becomes covered with fingerprints.
When opening the screen, a piano appears in the same color as the cover with a keyboard with black keys. The screen bezels are relatively narrow.
The quality of the keystrokes is okay. Most notably, the grainy coating on the keys and the somewhat rough screenprint give it a low-end appearance. The biggest downside is the missing backlight, which is all the more annoying with an almost tone-on-tone keyboard. As an aside, note the keyboard’s lack of consistency, with terms being translated into French (“Enter” key on the classic keyboard) and leaving others in English (“Enter” key on the numeric keypad). We also regret that the start button (top right of the keyboard) isn’t more prominent. You might also think it comes with a fingerprint reader, but it doesn’t; Forget the session unlock at the end of the index finger.
For its part, the sliding of the touchpad is comfortable and the gestures of Windows are well taken into account. However, left and right clicks tend to sink in a bit too much, and the click in the middle of the pad is particularly stiff, making one-finger selection or drag-and-drop impractical, especially on the top part of the pad. touchpad.
Samsung didn’t skimp on the connection and accommodates no fewer than two USB-C 3.2 ports, an HDMI port and a USB 3.2 port directly on the left side of the laptop. On the other side there is a second USB 3.2 port, a microSD reader and a mini jack. So there is no error on this page.
Wireless connectivity is entrusted to the Intel AX201 chip, which allows the Galaxy Book2 15 to benefit from Wi-Fi 6 at 2400Mbps and Bluetooth 5.2. The webcam, on the other hand, is less festive with its 720p sensor. The playback is just right for video conferences in good light; The lack of detail is evident and the digital noise is particularly present in low light conditions.
The Galaxy Book2 15 is cooled by a single fan accompanied by a radiator and a heat pipe. It’s all just the right size to cool the Core i7-1255U, which, recall, is a low-power 15-watt processor.
We measured 42°C at the hottest point of the keyboard under our thermal imaging camera after a calculation-intensive coding. The touchpad and the right half of the keyboard stay cool and were measured at less than 30 °C. However, you should avoid putting your fingers on the right part of the hinge where the warm air extraction is located.
The noise pollution of the Galaxy Book2 15 is controlled (34.1 dB measured in our new audio laboratory). In use, the Galaxy Book2 15 is discreet, but its fan tends to activate frequently.
The dismantling goes without any special problems. Simply remove four pads to gain access to the case’s opening screw. Detaching the hull is trickier and you have to be patient to avoid damaging the retaining clips.
When access is easy, the chances of evolution and repair remain slim. Only the battery and the SSD can be removed, the WLAN card and the main memory are welded. Good surprise though, the second free M.2 slot allows adding an SSD. Samsung announces a repairability index of 8.7/10 for our test model.
Samsung has provided us with a Galaxy Book2 15 equipped with an Intel Core i7-1255U processor accompanied by 16 GB of RAM and a 512 GB SSD. As a reminder, the Intel Core i7-1255U uses the Alder hybrid architecture Lake with 2 hyperthreading performance cores and 8 efficient cores. The manufacturer followed Intel’s recommendations for the thermal envelope: 15 watts with a very selective boost to 32 watts.
The Samsung Galaxy Book2 15 equipped with it achieves a performance index of 89. This puts it slightly behind MSI’s Modern 15 (95), but the latter boosts its processor with an envelope of 45 watts, which requires very regular frequency reductions. The Honor MagicBook 15, equipped with its AMD Ryzen 5 5500 processor, is just behind with an index of 87. The Core i7-1260P and the Core i7-12700H, which equip the Galaxy Book2 Pro and the MateBook D16, are clearly ahead.
During our practical coding, the P cores of the Core i7-1255U clocked at an average of 2.66 GHz and the thermal envelope was increased to 15.6 watts. Expected behavior and low consumption that confirm our impressions of the cooling system.
The SSD integrated by Samsung is an in-house model, the PM991a. The Galaxy Book2 15 reads at 2.2 GB/s and writes at 1.21 GB/s. These speeds are slightly below average, but more than sufficient to ensure operating system responsiveness and fast boot times.
The Galaxy Book2 15’s screen offers a modest spec sheet. The 15.6-inch PLS panel displays 1920×1080 pixels at 60 Hz and has a matte surface.
By default, our probe displays a panel that lacks fidelity (Delta E measured at 4.2, with a particularly pronounced drift on blue). The contrast is weak at 855:1, while the average of the most recently tested panels is around 1200:1. The color temperature is too high, well above the video standard (6500K) at 7493K, resulting in somewhat cold playback.
The maximum brightness of the panel is 329 cd/m², a value in the average of the tested laptops, which allows you to take full advantage of the Galaxy Book2 15 indoors. In addition, the panel’s low reflectivity (22% of reflected light) eliminates unwanted reflections.
Samsung offers software that allows you to slightly correct the colorimetry. To do this, open the Samsung settings and select the “Photography” profile, then lower the temperature to the minimum in the advanced settings. It achieves a Delta E of 3.8 and a temperature of 6859 K. However, the contrast suffers greatly and drops to 432:1.
The audio playback of the Galaxy Book2 15 is provided by two speakers located under the case. So the sound quality depends on the surface of the laptop and the positioning of the hands on the keyboard.
Listening reveals a volume that is large enough to watch 15 series even from a few meters away from the Book2. The sound reproduction, on the other hand, is very cavernous, with a blatant lack of bass and mids.
The headphone output will be able to compensate for the weaknesses of the loudspeakers, the measurements of which, apart from the somewhat low output power, turn out to be quite honorable. High impedance headphones should therefore be avoided.

Mobility / Autonomy
The Samsung Galaxy Book2 15 occupies an area of 35.6 x 22.9 cm contained in a thickness of 1.55 cm. The weight is also similar (1.55 kg plus 148 g for the 45-watt charger). Above all, it will be necessary to find a bag that can accommodate this large format.
Cold shower after the autonomy measurement: with its low-power processor, the Galaxy Book2 15 did not exceed 6 hours of video playback with our usual protocol (200 cd/m² screen, Netflix on Chrome). Admittedly, its 54 Wh battery doesn’t offer the best capacity, but the Honor MagicBook 15 manages just under 8 hours with a comparable battery and a Ryzen 5 5500U processor. You must therefore remember to take the charger on board when you leave for the day.

How does the classification work?
The Samsung Galaxy Book2 15 shows extensive connectivity and great performance. Unfortunately, they are achieved at the expense of a barely satisfactory autonomy, far from that of the Pro version of the laptop. The lack of a backlight and fingerprint reader are also a bit stingy, especially when your name is Samsung and almost all smartphones sell with these accessories.
