Should I choose ASUS Zenbook Duo or Lenovo Yoga 9I?

Verdict: Choose the ASUS Zenbook Duo first if multi-screen workspace on the go is the top priority; otherwise, choose the Lenovo Yoga 9i for a lighter, longer-lasting, and more versatile traditional 2-in-1 convertible experience.

Choose the ASUS Zenbook Duo for an expansive dual-screen desktop-style workspace, or select the Lenovo Yoga 9i for superior battery life, lighter weight, and refined 2-in-1 multimedia ergonomics.

The ASUS Zenbook Duo is the clear choice for intensive multitasking due to its dual 14-inch OLED touchscreens that deliver 19.8 inches of combined workspace, but driving both panels reduces battery life from its 75Wh pack to approximately 6 hours (8.5 hours in single-screen mode) while increasing carry weight to 3.64 pounds (1.65 kg) with the 1.4mm key travel detachable keyboard. In contrast, the Lenovo Yoga 9i is the stronger overall portable convertible, offering over 10 hours of endurance from the same 75Wh battery capacity, a lighter 3.09-pound (1.4 kg) and 0.6-inch thin all-metal chassis, superior 1.5mm key travel lap ergonomics, an upgraded 5.0MP webcam over the Zenbook Duo's 1080p camera, and a dedicated 4-speaker Bowers & Wilkins rotating soundbar hinge.
