Which is better for school and office work?

The IdeaPad Slim 3x. Its 16 GB RAM and 512 GB SSD handle more tabs and files, and its 14-hour battery covers a full day away from a charger.

Is the Snapdragon chip a problem?

Only if you rely on software that has no Arm version, such as some games and older specialty apps. Check your key programs first; mainstream browsers, Office and video calls work.

Which lasts longer on a charge?

The IdeaPad Slim 3x, rated at about 14 hours. Lenovo gives no battery-hour rating for the 3i, which has a smaller 47 Wh battery.

Is the 3x worth the extra $20?

Yes for most people. Double the RAM and storage plus much longer battery life is a large gain for $20 at Walmart as of November 7, 2026.

Which is better for gaming?

Neither is a gaming laptop. The 3i's Intel chip runs more games natively, but both rely on integrated graphics and suit only light or older titles.

Do both have a numpad and full HD screen?

The 3i has a numpad and a 15.6 in 1920x1080 matte screen. The 3x has a 15.3 in 1920x1080 IPS screen; a numpad is not listed for it.
