Lenovo Yoga Slim 7i Gen 9 vs Samsung Galaxy Book4 15"

The Verdict

Lenovo's Yoga Slim 7i Gen 9 and Samsung's Galaxy Book4 15" target different buyers entirely. The Lenovo excels with its 14.5-inch OLED touchscreen delivering 2880 x 1800 resolution at 120Hz with 400 nits brightness, paired with Intel's newer Core Ultra 7 155H processor featuring 16 cores and 1TB storage. Battery endurance stretches to 14 hours, and the 1.5kg chassis remains impressively thin at 14.9mm. The Samsung counters with a larger 15.6-inch display but relies on dated 1920 x 1080 IPS technology, 60Hz refresh, and lower brightness (300 nits). Its 10th generation Core i7-1355U processor delivers adequate performance for office work, though only 512GB storage and 10 hours battery life feel restrictive. At $1199, the Lenovo justifies premium pricing through superior display technology, newer processor architecture, and business-focused features like two Thunderbolt ports. The Samsung at $749 appeals to budget-conscious users prioritizing screen real estate over quality, accepting compromises on refresh rate and storage capacity. For anyone who values creative work, coding, or content consumption, the Lenovo's OLED screen and modern processor justify the investment. The Samsung works for basic productivity but feels dated for its price range.
