Our Verdict
Lenovo Yoga Slim 7i Aura Edition 15 (2024)
Lenovo ThinkPad X9 15 Aura Edition (2025)
The Lenovo ThinkPad X9 15 Aura Edition (2025) and the Lenovo Yoga Slim 7i Aura Edition (2024) are both ultraportables featuring Intel Lunar Lake chips, delivering nearly identical performance. However, the ThinkPad X9 is an even more premium device, sporting a sturdier build, a haptic touchpad, and a better 1440p webcam. The X9 also has a better battery life, lasting nearly four hours longer in light uses. That said, if you're sensitive to display flicker, know that the X9 is only available with OLED displays that flicker at 480Hz, while the Yoga Slim 7i has a flicker-free IPS panel option.
