Where recent Samsung laptops have impressed in this department, this machine put in a middling show. It lasted 11hrs 35mins in our video rundown test, which isn’t bad, but it’s a long way behind the standard set by the M1 Apple MacBook Air and M1 MacBook Pro. We conducted three separate battery life tests, which tasked the laptop with continuously surfing the web over Wi-Fi with the screen set to 150 nits of brightness. On average, the Galaxy Book 3 Pro 360 lasted for 7 hours and 46 minutes. This is an abysmal average on its own, but when compared to its predecessor which lasted four hours longer, it's horrendous.

Middling battery life aside, deciding whether or not you want the Galaxy Book 3 Pro 360 arguably comes down to how invested you are in the Samsung ecosystem. Multi Control and features meant to work in tandem with other Samsung devices are a major selling point. However, if you own one of the best iPhones or the best iPads, you won't be able to utilize this laptop's Samsung-specific features. The fact that I can have so many open tabs with a video running speaks well of this laptop's performance. But how did it do in our official testing?Plus, with Studio Mode, you'll be camera ready with super smart features - including AI Noise Cancelling and Auto Focusing. The wide camera and and studio quality mics ensure you sound your best on every video call.

The Galaxy Book3 Ultra is currently the most powerful gaming and professional laptop sold by Samsung. It includes Samsung's most innovative features, putting next-level performance at the forefront. It boasts a magnificent 16-inch WQXGA+ Dynamic AMOLED 2X display for a larger and more expansive viewing experience. Weighing in at just 1.79Kg its ultra-thin and light, offering superior portability and flexibility. Overall, it’s a very attractive laptop but there are a few too many compromises for it to warrant a wholehearted recommendation. You do have to pay attention to the performance mode you are in, though. A keyboard shortcut swaps you between Silent, Quiet, Optimised and High Performance modes.And brightness? While the Samsung Galaxy Book 3 Pro 360 gives off a fantastic impression of brightness thanks to its ultra-high contrast, we only measured peak brightness at around 400 nits. That's solid, but the top MacBook Pros can reach 1000 nits, or a dazzling 1600 nits when showing HDR content. 400 nits is the minimum we’d expect for a laptop this pricey. The Galaxy Book3 is an exceptional everyday laptop, that offers next-level performance and stylish design features. With an expansive 15.6-inch display it brings together a large FHD screen with a contemporary lightweight form, weighing in at just 1.6kg. The Galaxy Book3 offers exceptional continuity within the Samsung Galaxy Ecosystem, allowing you to work smarter, not harder.

You can even use your Galaxy Tab as a Second Screen , while using your laptop mouse and keyboard to manoeuvre between different devices ⁵. What’s more you can directly sync photos taken with your Galaxy smartphone using Expert Raw so your images auto transfer, uncompressed, from your smartphone to laptop ⁶. From here you can access studio-level post-editing via professional apps such as Adobe Lightroom ⁷. The Galaxy Book3 is certainly a superb laptop for a wide range of everyday uses.
