Samsung Galaxy Book4 Pro 360 Review: A Gorgeous 16" OLED Laptop
Samsung Galaxy Book4 Pro 360 Review: Battery Life, Thermals, And Our Conclusions
To test the Samsung Galaxy Book4 Pro 360's battery life, we used PCMark 10's video loop test. We set the screen brightness to as close to 115 lux as possible, and also left Wi-Fi on, since most users are likely to stream HD media from the internet and not locally.
Samsung Galaxy Book4 Pro 360 Battery Life
The Samsung Galaxy Book4 Pro 360 scored really well here, running for over 15 hours straight. This is well short of the MSI Prestige 16 AI Evo's 20 hours, but it's important to note that the MSI laptop had a 99.9Whr battery, which undoubtedly helped it last much longer. With 15 hours of battery life (and maybe more depending on what you're doing), most users will likely be pleased by the Samsung Galaxy Book4 Pro 360.
Samsung Galaxy Book4 Pro 360 Acoustics, Power, And Thermal Performance
We tested the Samsung Galaxy Book4 Pro 360's acoustics and thermals using the CPU benchmark Cinebench R23, with the system configured to use its default optimized power profile, and recorded data using HWInfo and a decibel meter.
At 44 decibels flat under load, the Galaxy Book4 Pro 360 was relatively quiet. 44 decibels is more noticeable than the laptop at idle or when under a lighter load, but it's not obtrusive in our opinion. If you'd prefer things stay quieter, the lower-power silent and quiet profiles are also an option, though you'll have to sacrifice a bit of performance. Of course, only expect the fan to ramp up under heavy load; while browsing or watching videos, the fan barely spins up if at all.
Given that the Galaxy Book4 Pro 360 is thin and light and targets typical computing use cases, it's optimized for power efficiency, and that was certainly evident in our testing. The Core Ultra 7 155H has a TDP of 28 watts, but Intel also permits the chip to briefly turbo up to 115 watts. Samsung didn't utilize the full 115 watts the 155H is capable of, likely due to thermal constraints, but it did hit a peak of 68 watts at the start of the test. After this boost, it quickly set into its nominal TDP of 28 watts.
Power consumption is directly correlated with temperature, and naturally the CPU temperature peaked alongside its peak power draw. Right at the start of the test, the chip shot up to above 90 degrees Celsius, hitting a maximum of 98 degrees. The temperature only fell below 90 degrees about 40 seconds into the test, and gradually declined to the low 80s by the time the benchmark was finished. That's certainly hot, but well within Intel's thermal specifications.
Samsung Galaxy Book4 Pro 360 Conclusions
In comparison to most other laptops with a 16" form factor, Samsung differentiates its Galaxy Book4 Pro 360 with its thin and light profile, touch screen, tablet conversion capability, and included stylus. Touch screen functionality is essentially a prerequisite for a convertible, but Samsung augments the capability with the excellent S-Pen for users that prefer stylus input.
The display in the Samsung Galaxy Book4 Pro 360 is also beautiful, as you'd expect from OLED-based technology. The display offers excellent 120% DCI P3 color volume and a crispy 3K resolution, which is a good match for the 16" panel size. The premium aluminum chassis is also great, as is the large trackpad. The keyboard is also pretty good given the machine's thinness, and it includes a 10-key numpad, which can be a huge help for many productivity applications.
The Core Ultra 7 155H in the Galaxy Book4 Pro 360 doesn't really offer much more CPU performance over previous-gen Intel mobile platforms, but it incorporates an NPU, which can offload some AI workloads from the processor cores to improve efficiency. Intel's Core Ultra 7 also has a much more powerful integrated GPU. While you're unlikely to be gaming much on a laptop like this, the Galaxy Book4 Pro 360 is very capable of light duty gaming.
The Samsung Galaxy Book4 Pro 360's storage and memory configurations leave a little something to be desired, however. The SSD in the machine isn't particularly fast, though it is likely very power consumption friendly. Additionally, we would have liked to see a 32GB RAM option, since 16GB is the bare minimum we'd recommend these days for the Windows 11 experience. A 32GB model would probably cost a couple hundred dollars more, but we think many users would appreciate the option.
The Galaxy Book4 Pro 360 is not perfect and the 16" convertible form factor and may not be for everyone with it's larger 16-inch footprint. However, it does offer great battery life, touch input, a stunningly beautiful OLED display, and premium build quality. It's also currently on sale for $1499, which is a competitive value for a premium, convertible laptop with these features and capabilities. If you're in the market for a high-quality, thin-and-light machine, and prefer a larger display and the flexibility of a 360 degree hinge, the Samsung Galaxy Book4 Pro 360 is definitely worth considering in this age of the AI PC.
