The appearance of the Lenovo YOGA Slim 7 Gen8 closely resembles its predecessor, with a noticeable upgrade in the form of an exceptionally narrow bezel design that features a larger 14.5-inch screen. Coupled with its 16:10 screen ratio, this enhancement results in an 11% increase in the display area, offering users a more expansive visual experience.

Lenovo’s YOGA series introduces a shiny design style to their notebook lineup for the first time. They’ve carefully polished the sides of the laptop in ten steps, creating a smooth and shiny edge that not only looks great but also feels nice to the touch. This extra care in design makes the notebook stand out in terms of both its appearance and how it feels when you use it.

This laptop aims to provide an attractive visual appeal and a comfortable user experience to meet diverse computing requirements.

Lenovo YOGA Slim 7 Gen 8 Review: Display

The Lenovo YOGA Slim 7 Gen8 is equipped with a compact 14.5-inch OLED screen. It supports a higher 3K resolution (2944x1840p) with an aspect ratio of 16:10 and can get bright at 400 nits, so you can see everything clearly, even in sunlight. Thanks to a 90Hz refresh rate, the screen feels super smooth while usage.

One of the most prominent things about this 14.5-inch display has several certifications. The display has the following certifications: Dolby Vision (for having great colours and contrast), Display HDR 500) for showing pictures in really great form), EyeSafe 2.0 (integrates hardware-level anti-blue light technology to ensures eye safety during long-term use) and TÜV Low Blue Light Certification.

Lenovo YOGA Slim 7 Gen 8 Review: Keyboard & Ports

The all-new Lenovo YOGA Slim 7 Gen8 is equipped with the YOGA 6-row keyboard. The keys on the keyboard are designed in a way that makes it able to offer unbeatable speed and accuracy in typing. The keys offer 1.5mm key travel and a nice bounce-back, making it comfy and efficient to use. And no need to worry about spills – it’s designed to resist dirt and splashes, thanks to a special coating.

In addition, the keyboard also supports a backlight that adds a cool and rhythmic vibe to the keyboard. Not only that, it also features a smart lighting feature that turns on automatically in low light.

Lenovo YOGA Slim 7 Gen 8 Review: RAM, SSD and Network

Beginning with the RAM, the Lenovo YOGA Slim 7 Gen8 comes with 32GB LPDDR5x memory, which is soldered onto the motherboard, making it non-upgradable. It’s essential to note that this memory operates in Dual Channel mode and runs at a clock speed of 6400MHz. Additionally, Lenovo offers two RAM configurations for this laptop: one with 16GB of RAM, and the model we have features 32GB RAM.

We also conducted a RAM test using the AIDA64 Memory and Cache benchmark application in which we got the following results: 50,708MB/s Read Speed, 93,312MB/s Write Speed and 69,198MB/s Copy Speed. The latency rate was measured at 120.8ns. The Write Speed is impressive but worth noting that the Read Speed was relatively lower in comparison.

Moving on to the SSD, the Lenovo YOGA Slim 7 Gen8 is compatible with M.2 2280 PCIe 4.0 SSDs and has four slots for storage. The version we tested comes with a 1TB Samsung PM9A1 SSD (an OEM variant of the Samsung 980 Pro). Interestingly, upon disassembly, we discovered that the manufacturer applied the thermal paste to the SSD, allowing the laptop’s metal bottom cover to act as a heat sink, reducing heat generated by this component.

It’s important to note that this notebook is available in two storage options: 512GB and 1TB.

For the benchmark test, we used the CrystalDiskMark benchmark application. The results were as follows: 6651.72 MB/s Sequential Read Speed, 4943.01 MB/s Sequential Write Speed, 65.24 MB/s 4K Read Speed, and 105.89 MB/s 4K Write Speed. We also conducted a second test using the AS SSD Benchmark application, where the SSD achieved a total score of 4121. It exhibited an impressive sequential read speed of 4506MB/s and a write speed of 2111MB/s. Even the 4K read and write speeds surpassed 61MB/s and 125MB/s, respectively.

In short, the SSD performance of this laptop, especially in terms of sequential read and write speeds, is remarkable, ensuring speedy data access and transfer capabilities.

Lenovo YOGA Slim 7 Gen 8 Review: Battery and Charging

When it comes to battery life, the Lenovo YOGA Slim 7 Gen8 boasts a 70Wh battery, which is more than sufficient for a 14-inch notebook. Interestingly, even though it’s a thin and lightweight laptop, the battery module takes up a significant amount of space inside.

This battery is a Li-ion type with a capacity of 4522mAh. According to the official claims, the laptop can run for approximately 9.6 hours (at 200 nits brightness) in the MobileMark 2018 benchmark software. When playing a regular Full-HD (1080p) video, you can expect an impressive 14 hours of playback time. This kind of battery life is excellent for a laptop designed for office use.

We also conducted a battery life test using PCMark 10 software. We enabled the energy-saving mode, closed all other programs, turned off Wi-Fi, and adjusted the screen brightness to 50%. Under these conditions, the laptop delivered an impressive battery backup of 14 hours and 08 minutes. This level of battery life should easily support 1 to 2 days of office usage without needing a recharge.

In addition to a large battery, the Lenovo YOGA Slim 7 Gen8 comes with a 65W USB-C slim (2-pin, wall-mount) AC adapter, which supports PD 3.0. The charger charges at following modes: 15W (5V/3A), 27W (9V/3A), 45W (15V/3A) and 65W (20V/3.25A). Another positive aspect of this charger is that you can also use it for charging your fast-charging supported phones. According to Lenovo, a quick 15-minute charge can give your laptop an extra 2 hours of battery life. But just remember, this fast charging is only effective when your laptop is either in hibernation mode or completely turned off.

Lenovo YOGA Slim 7 Gen 8 Review: CPU and its Benchmark

Lenovo YOGA Slim 7 Gen 8 Review: Heat Dissipation and Stress Testing

On dismantling the notebook, the heat dissipation system of the Lenovo YOGA Slim 7 Gen8 can be judged properly. The body is quite thin but still, the manufacturers have managed to add dual fans and dual heat pipes in this Ryzen 7 7840S powered notebook which has a max performance release of 30W.

CPU Stress Testing: For doing the stress test on the CPU, we used the AIDA64 FPU. Before telling the test results, it is worth mentioning that this test was carried out in a room where the temperature was 28.2°C. After almost 15 minutes of testing, the power consumption of the CPU was stabilized at 30W and its temperature was around 74°C while the frequency was 3.2GHz.


In the end, we can say that the Lenovo YOGA Slim 7 Gen8 is a good option in the world of business laptops, thanks to its sleek design and powerful performance. It comes with the Ryzen 7 7840S processor, a speedy 32GB LPDDR5x RAM, and a lightning-fast 1TB Samsung SSD into a visually appealing and lightweight frame.

One of its standout features is the 14.5-inch OLED display with a sharp 3K resolution. This screen offers vibrant colours and impressive brightness, and it’s certified for Dolby Vision, Display HDR 500, and EyeSafe 2.0, ensuring a fantastic visual experience. The display is perfectly calibrated for accuracy and includes a high-quality integrated FHD webcam.

The YOGA Slim 7 Gen8 doesn’t disappoint in terms of battery life as well, and it supports fast charging.

  1. I really like this laptop and I’m thinking about buying it, but I’m worried about one thing and that’s the burn-in effect of this OLED display. Can someone please share their experience with this model or OLED display? Thank you in advance.

    1. The reason for OLED screen burning is that the luminous duration and intensity of the lamp beads in each area of the screen are inconsistent during use, resulting in different degrees of aging between the lamps, so that some lamps become darker, have serious color casts, and some are not serious.

      Therefore, on the entire screen, the degree of aging in the areas where certain content is often displayed will be heavier and the light beads in these areas will be darker than the brightness of other areas, and the color shift will also be heavier, just like leaving an imprint, which is what everyone calls screen burning.

      Although the OLED screen used in the current market is a relatively new technology, especially the OLED screen used by some first-line manufacturers, the OLED screen with the latest technology is basically used. But the characteristics of OLED are like this, so OLED screen will burn after a long time.

      Another disadvantage of OLED is that the cost of replacing the screen is very high, and it costs 1-2 times more than the cost of the LED screen.
