Lenovo IdeaPad Slim 3i 15 vs Lenovo IdeaPad Slim 3x 15.3" Laptop

The IdeaPad Slim 3i is the better pick for most people. Its Intel Core Ultra 5 runs full Windows apps without the compatibility caveats of an Arm chip, and it has a sharper 1920x1200 screen, a touch option, and RAM you can upgrade to 40 GB. The Slim 3x wins on battery life and has a much larger review base, but its Snapdragon X X1 is an entry-level Arm chip with soldered 16 GB RAM and weaker graphics. Buy the 3i unless all-day battery matters more than app compatibility.

  • Choose the IdeaPad Slim 3i if you run standard Windows software, want a touchscreen and upgradeable memory, or need more graphics headroom for light editing.
  • Choose the IdeaPad Slim 3x if you mostly browse, write, stream and take video calls, and you want the longest battery life with a quiet, cool-running machine.

Questions and answers

Which is better for school or office work?
The Slim 3i. Its Intel chip runs every standard Windows app natively, and the touchscreen and upgradeable RAM help over several years of use.
Which lasts longer on a charge?
The Slim 3x, rated at 14 hours against 11 for the 3i. The Arm chip draws less power, so it also runs cooler and quieter.
Will my software run on the Snapdragon model?
Most everyday apps do, but some run through emulation and a few, including certain games and older business tools, do not work at all. Check your key apps before choosing the 3x.
Is the 3i worth stepping up to?
Yes for most buyers. You get full app compatibility, a touchscreen, upgradeable memory and stronger graphics. Step down to the 3x only if battery life is your top priority.
Can I add more RAM later?
On the Slim 3i, yes, up to 40 GB. On the Slim 3x the 16 GB is soldered, so buy the configuration you need from the start.
Which is better for photo or video editing?
The Slim 3i. Intel graphics and expandable memory handle light editing better, though neither is a workstation for heavy video work.
