Lenovo IdeaPad Flex 5 14 (2024) vs Samsung Galaxy Book4 15"
The Verdict
Both laptops occupy the same affordable convertible space but with different strengths. The Lenovo IdeaPad Flex 5 14 offers a more compact 14-inch display at 1920x1200 resolution with superior portability at 1.55 kg, plus two USB-A ports versus Samsung's single port. Battery life reaches 12 hours compared to Galaxy Book4's 10 hours. The AMD Ryzen 5 7530U provides solid everyday performance for the price. Samsung's Galaxy Book4 15 counters with a larger 15.6-inch screen, better Intel Core i7-1355U processor (10 cores with hybrid architecture), and includes 16GB RAM standard while the Lenovo starts at 8GB. Storage comes at 512GB across most configs. Galaxy Book4's larger display suits media consumption and spreadsheet work, though its 1920x1080 resolution spreads pixels thinner across the bigger panel. The Lenovo's lighter weight, longer battery life, and extra USB connectivity make it better for frequent travelers. Samsung justifies its $100 premium with processor performance and larger screen. For budget shoppers prioritizing portability and battery endurance, the Lenovo delivers better value. For those wanting a true 15-inch work machine with stronger CPU performance, Samsung edges ahead despite lower battery ratings.
