Lenovo Yoga Slim 7x with Qualcomm Snapdragon X2 Elite shows impressive battery life and performance in early tests

YouTuber Dave2D recently published a preview video for his upcoming Snapdragon X2 Elite Lenovo Yoga Slim 7x review and what immediately stands out is the impressive battery life. It does not quite match the initial Lenovo claims, but it is still beating a MacBook Air.

While the Qualcomm Snapdragon X2 Elite can in certain local video playback scenarios achieve up to 31 hours of battery life, the chip is consistently hitting almost 25 hours with the Lenovo Yoga Slim 7x 2026 70 Wh battery. Not quite there yet, but we should bear in mind that Dave2D tested a pre-production unit. Nevertheless, the new chip’s battery life is 6 hours longer compared to the first X Elite chip models from 2024 and it even beats Apple’s latest MacBook Air models.

What about performance? Dave2D shows a Cinebench 2024, and for the multi-core test we see the X2 Elite chip comfortably outclassing by around 20% all similar chips available right now such as the AMD Ryzen AI 9 HX 470, the Intel Core Ultra X9 388H and the Apple M5. Single core performance is inferior to an M5, but it beats the Intel and AMD competition.

Are these synthetic theoretical results holding true in real life scenarios though? Indeed, the X2 Elite actually beats the competition in Blender and it is mostly in line with the AMD and Intel competition in Premier Pro. However, most importantly, the X2 Elite chip shows the exact same performance whether it is plugged in or just running on battery, a feat that is rarely achieved by the Intel and AMD competition.

On the software side, Dave2D notes that most of the Windows-on-ARM apps are now native and the compatibility problems that still plagued the 2024 version should be solved. Games, on the other hand, still mostly rely on Prism emulation, but the iGPU performance is quite good at least on 1080p medium. Sadly, there still are games that cannot run on the X2 Elite, like Apex Legends, Valorant or LoL, because of anti-cheat systems.

As far as improvements for the Yoga Slim 7x 2026 go, Lenovo maintained a low weight of 1.17 kg, reducing the screen size by around 0.5 inches (14-inch now instead of 14.5-inch previously). Speaking of the screen, it now features a 2.8K 120 Hz OLED panel with 100% P3 and aRGB plus 1100 nits maximum brightness. The flat heatpipe cooling system keeps the machine quiet and cool even in high loads if set to Quiet mode (at most 28 dB), while in Performance mode it may still reach 43 dB. The audio system features 4 speakers instead of 2.

Lenovo initially announced the 16 GB RAM configuration of the Yoga Slim 7x 2026 would start at $900, but given the RAM and storage shortages, these prices could go over $1000 whenever the models become available.
