Our Verdict

Lenovo IdeaPad Slim 3i 15 (2023)

Lenovo IdeaPad 3 15 (2021)

The Lenovo IdeaPad Slim 3i 15 (2023) and the Lenovo IdeaPad 3 15 (2021) are very similar overall. The Slim 3i has a better keyboard and a more responsive touchpad, and its USB-C supports video output and charging. Also, the IdeaPad Slim 3i is available with newer and faster Intel 13th Gen. CPUs. However, the IdeaPad 3 15's screen gets slightly brighter to combat glare, and its battery lasts longer.
