Design, Display, Ergonomics, & Build

The realme Book Slim gives you a premium look and feel when it comes to the design, the design is unbelievable, slim and compact, metallic design, and light in weight at 1.38 kilograms. It has an impressive slim form factor 14-inch size and 14.9 mm thin making it one of the slimmest laptops in its class.

The notebook has a high-quality aluminum body and a great 2K display on-board, it grabs your attention when you look at its gorgeous 2K display. The display here is a 2K QuadHD with 2160 x 1440 pixels resolution, 60 Hz refresh rate, 3:2 aspect ratio, 100% sRGB color gamut, and is protected by an Anti-glare sheet.

The screen looks large with minimum bezels and gives you a great viewing experience. Its competitor, the Mi NoteBook Pro offers a slightly higher resolution display i.e. 2.5K (1560 x 1600 pixels) with over 1B colors (Mi TrueLife display).

The front side has a realme logo, the backside has vents with loudspeakers grill at the sides, the notebook opens wide almost 180-degree, the overall design is solid and looks premium. The notebook offers a 3-mode backlit with an extra-large trackpad and a fingerprint scanner embedded on the power button. The keyboard and trackpad experience has been great so far.

The right side of the laptop offers a 3.5 mm combo port (microphone + headphones) and a USB Type-A 3.1 Gen 1 port. The left side offers two USB Type-C ports, one of which is the 3.2 Gen 2 version (upper one) and Thunderbolt 4 (lower one) with a LED charging indicator in the middle. You don’t get an HDMI port and RJ-45 LAN port, you will have to use a converter/adapter.

Software & Features

The realme Book Slim runs on the latest Windows 10 Home Single Language (21H1 version) pre-installed with no sign of bloatware, you will find a PC Connect app along with a few apps from Microsoft pre-installed with the laptop, the interface is clean and free from bloatware.

Upon using it as an everyday laptop with multi-tasking, browsing, surfing, downloading files, streaming videos and music, and light gaming, and it turns out that the overall experience was great, smooth as well as responsive.

The built-in PC Connect app connects with your realme smartphone with the notebook and allows you to access the files on the phone, transfer the files, and allows you to perform certain activities on both devices.

On the connectivity side, it comes with a Wi-Fi 6 dual-band (802.11ax) 2.4 GHz and 5 GHz, newer Bluetooth version 5.1 (5.2 on Core i5 models), 1x USB Type-C port for charging as well as for data transfer, one Thunderbolt 4 port on the left, and one USB Type-A on the right

This can be a downside, no HDMI output and RJ-45 LAN are found on the laptop due to its slim profile. You may use a Type-C converter to HDMI, but without the converter in hand, you are out of luck.

The speakers are fair, the audio output is decent, you get 2x Harman Kardon stereo speakers with DTS Audio Stereo Surround support. You will also find an HD webcam with built-in 2x microphones just beside it using the Vocplus AI Noise Cancellation algorithm.

Hardware, Performance & Gaming

realme offers the notebook in two processor variants, i.e. Intel Core i3 and Intel Core i5 both 11th generation. The realme Book Slim is equipped with Intel’s latest 11th generation code name Tiger Lake CPUs: Core i3-1115G4 dual-core (quad-thread) and Core i5-1135G7 quad-core (quad-thread), but no Core i7 variant.

A downside is that the RAM isn’t upgradeable, you will end up with only 8 GB on the laptop which might be a setback for those who are planning to upgrade the RAM in the future. You also don’t get any 12 GB or 16 GB RAM variants in it.

The SSD storage performance is incredibly fast, it’s an NVMe, the faster SSD type, it has after all better performance among the regular SSDs and far better than its HDD counterparts. The SSD storage plays an important role in the overall system performance.

Aside from these, you get a gorgeous 2K display, a large trackpad, backlit keyboard, and fast charging capabilities which makes the realme Book Slim a comprehensive package.
