Apple MacBook Air 13-inch (M4) vs Lenovo IdeaPad Slim 3 15" Gen 9

The MacBook Air M4 is the better laptop for most people deciding between these two. It has a sharper display, far longer battery life, a much faster chip and a lighter build, and owners rate it highly. The IdeaPad Slim 3 is a bigger-screen Windows machine with a fingerprint reader and more ports, but 8GB of RAM and a 60Hz panel limit it to light tasks. Choose the Air unless you need Windows or a larger screen on a tight budget.

  • Choose the MacBook Air M4 if you want a light, fast laptop with long battery life for work, study, photo and video editing, or everyday multitasking.
  • Choose the IdeaPad Slim 3 if you need Windows, prefer a 15.6-inch screen, and mainly do browsing, email, documents and streaming.

What reviewers say

Apple MacBook Air 13-inch (M4)

  • 4.7 / 536 ratings

Owners rate the M4 Air highly, praising its speed, silence and battery life for everyday work. Complaints center on the small base storage and the limited port count.

What people mention
  • PerformancePraisedOwners say the M4 chip stays quick across many open apps and light editing.
  • BatteryPraisedReviewers report all-day battery life close to Apple's 18-hour claim.
  • NoisePraisedThe fanless design runs silent even under sustained load.
  • StorageCriticisedBuyers say the 256GB base SSD fills fast and upgrading at purchase is costly.

Lenovo IdeaPad Slim 3 15" Gen 9

Owner feedback on the IdeaPad Slim 3 line is generally positive for the price, with people calling it a solid everyday machine. Complaints center on the dim display, average speakers and the amount of preinstalled software.

What people mention
  • ValuePraisedOwners say it delivers the essentials for less than most 15-inch rivals.
  • DisplayMixedThe 1080p panel is sharp, but reviewers find it dim and low on color punch.
  • KeyboardPraisedTyping feel and the number pad get consistent praise.
  • SpeakersCriticisedSound is described as thin and quiet, fine for calls but not media.

Questions and answers

Which is better for students?
The MacBook Air M4 suits most students better. It lasts a full day on battery, is light to carry and stays fast across many apps. The IdeaPad is a reasonable pick if your course needs Windows-only software.
Which lasts longer?
The MacBook Air has the longer battery life by a wide margin, up to 18 hours versus about 8. Its aluminum build and fanless design also tend to hold up well over years of use.
Is the MacBook Air worth stepping up to?
Yes for most buyers. The M4 chip, sharper screen, 16GB of memory and much longer battery life make it the stronger machine for years of use. Step down only if you need Windows or a bigger screen.
Can the IdeaPad handle video editing?
Only light editing. 8GB of RAM and a 60Hz panel slow down timeline scrubbing and exports. The MacBook Air is the better choice for video work.
Which has better ports?
The IdeaPad has more built-in ports, including USB-A and HDMI. The MacBook Air relies on two Thunderbolt 4 ports, so plan on a small adapter or hub.
Which screen is better?
The MacBook Air's Liquid Retina display is sharper and more colorful. The IdeaPad's 15.6-inch matte screen is larger and easier to read in bright light, but lower resolution.
