Lenovo Yoga Slim 7x Review: Thought OLED was overrated?

Lenovo Yoga Slim 7x Review: A Stunning OLED Marvel with Creative Flair.

The Lenovo Yoga Slim 7x represents laptop excellence through its combination of Qualcomm Snapdragon X Elite processor with OLED display technology. The creator-designed device provides strong performance and great battery life with its slim design yet it comes with a few minor limitations. The machine proves itself to be one of the top laptops of 2025 following extensive evaluation.

The 12-core Snapdragon X Elite X1E-78-100 operating at 3.4GHz within the Yoga Slim 7x enables it to handle demanding computing requirements. The system supports seamless multitasking thanks to its up to 32GB soldered RAM capacity which enables users to run demanding applications such as video editing or simultaneous browser usage. My testing of CPU-intensive applications led to flawless performance that secured this machine a place among my top picks. The 14-inch 3K display (2944 x 1840) with 90Hz refresh and True Black HDR 600 certification stands as the highlight of this device. The display shines at 600 nits and achieves infinite contrast and deep blacks that match or exceed my Alienware AW3423DWF QD-OLED monitor’s HDR 400 mode brightness. I used the HDR Calibration app from Windows 11 to adjust color settings which preserved clarity so that movies and creative tasks appeared vibrant. X-Rite Color Assistant provides users with P3, DCI-P3, Adobe RGB, sRGB, and Rec. 709 colour modes but users must turn off HDR mode for compatibility.

Battery life is a standout. The device ran for 2 hours and 34 minutes at 80% battery life with HDR on while watching YouTube videos at maximum brightness. When the battery was full and the brightness was set to 20-30% the system lasted two hours before needing to recharge and continued running for 2 hours and 50 minutes under heavy load before dropping to 48%. The results match leading laptops so users can operate all day without needing to recharge their battery when they manage screen brightness. The battery drain at 47% appeared as a review-specific issue yet it did not affect the device's overall dependability.

The design is equally impressive. This slim laptop weighs 1.28kg while feeling premium due to its backlit keyboard that includes a useful on-screen caps lock indicator. The laptop has only three USB-C ports while it does not have USB-A, HDMI or a headphone jack. Users need a dock for connecting legacy devices despite the thin profile of this device. The built-in speakers perform poorly yet the Lenovo Vantage sound presets provide some improvement. The touchscreen function was mostly unused because it would damage the beautiful OLED display even though it operated well. The device does not convert between tablet and laptop modes so this feature stands as an unessential addition. The thermal performance remained consistent despite minimal ventilation because the design showed excellent engineering.

The device fails to deliver good gaming performance. The 3K resolution and Snapdragon processor experience issues when playing demanding games. Hades maintained a 80fps frame rate at its native resolution yet Sifu managed only 60fps at 1440p with low graphics settings. Resident Evil 4 crashed multiple times despite driver updates before it managed 20fps at 720p. The 16:10 screen ratio restricts possible resolutions to 1080p among others. Users who prioritize gaming should choose different options.

The Yoga Slim 7x costs $1,049 for the US market and £1,249.99 in the UK and AU$2,609 in Australia although its premium pricing is understandable given the exceptional OLED display and Snapdragon multi-core performance that competes with Apple M3 processors in workloads. Users can purchase this laptop at a relatively affordable price compared to OLED monitors and TVs on the market. This laptop provides unmatched visuals and performance to professionals and creatives although gamers and port enthusiasts will require different alternatives.
