Here is an extensive review so you know what you are buying before you drop 3 grand on a laptop. Quick caveat: I have the NVIDIA RTX 5060 chip instead of the Intel graphics model.
Battery Life & Efficiency
First, and what I would consider the focal point, is the battery. I have read many reviews thus far about this thing's battery life, and all of them are accurate. You should easily be able to get a full day on one charge if you are not doing heavily demanding tasks. The Book 6 Ultra ships with an 80,000 mWh battery (if you are not a battery nerd like me, the average battery size for a standard laptop is around 50,000 to 65,000 mWh, so it's a pretty big difference). In some cases like mine, the laptop actually seems to ship with values over that 80,000 mark to ensure Samsung is accurate with their statistic. Having a big battery is important, but just as important is how the device allocates its energy. Samsung did really well with the efficiency of the Book when running on battery.
Display & Brightness
Moving on to the display. This is one of the best AMOLED screens on a laptop to my recollection. It can get up to 1,000 nits (on the brightness scale)—to put it in simple terms, it will be bright enough! It's also a touch screen, which is a cool feature for some people. It uses Corning Gorilla Glass, which is very good at preventing screen glare and reflection. My favorite part about the screen is its refresh rate. It can get up to 120Hz (Hertz), which is the same refresh rate as the best Xbox (Series X) on the market, and should be plenty for most people who want to play games on this device.
Performance & Cooling
This brings me to performance and cooling. If I had any digs on the Book this year, this would be it. Please remember I have the NVIDIA graphics card before you read this. The stability on this thing is surprisingly consistent given that the body is only 15.4mm thin. What I mean by stability is the amount of FPS (Frames Per Second) that is obtained and maintained throughout a gaming session. For example, one of the hardest games to render on any device is Call of Duty, specifically Warzone, and I am able to maintain a solid 120 FPS while still being on a native 4K resolution (this is without NVIDIA's 'Frame Generation').
Now for the actual dig: the cooling on both the Book itself, but more so the charger. The charging block can support Super Fast Charging 2.0, which produces 140W from a USB-C charger (which is included in the base box, no upgrade needed). However, there is something called "Power Dipping." Like what it sounds, when you are playing a game for a long period of time, that NVIDIA card is power-hungry, and sometimes it can pull more electricity than the charger can produce. You will actually see your battery "dying" even when it's plugged in. The charging box will also slow itself down when it detects it gets too hot, which is good so it doesn't hurt itself, but it will make the battery dip more extreme.
The Little Extras
The final couple of "little extras" worth mentioning are the Wi-Fi 7 and Bluetooth 5.4 chips, which are both top-end on the market right now. It also features a six-speaker system tuned with Dolby Atmos. Most laptops only have 2 or 4, so that's a cool upgrade. Lastly, the haptic trackpad gives a clean response anywhere on the pad itself.
Final Verdict
5 stars is a worthy review for this device. You are paying premium money for a premium device that I can tell is built to last. If anyone is nitpicky about things, it would be me. As long as you take adequate care of your Book, it will last you for as long as you will need it.
