MacBook Air M5 vs M4: What’s the Difference?

Apple’s MacBook Air lineup continues to evolve with each generation of Apple silicon. The MacBook Air M4 already offers powerful performance, long battery life, and a sleek lightweight design, making it a popular choice for students and professionals. The newer MacBook Air M5 builds on this foundation with faster processing, improved AI capabilities, better connectivity, and increased storage options. In this guide, we compare the MacBook Air M4 vs MacBook Air M5 to help you understand what has changed and which model is the better choice for your needs.

MacBook Air M5 vs M4: Difference in Display and Design

If you put the M4 and M5 MacBook Air side by side, you wouldn’t be able to tell them apart. They share the same slim, wedge-less aluminum body in both 13.6-inch and 15.3-inch sizes, with the same port setup: MagSafe 3 for charging and two Thunderbolt 4 ports. The display is also unchanged. You still get the bright, sharp Liquid Retina screen with 500 nits of brightness, P3 wide color, and True Tone. There’s no OLED and no 120Hz ProMotion here, so visually, the experience is exactly the same on both models.

MacBook Air M5 vs M4: Difference in Storage

This is where the M5 starts to feel like a meaningful upgrade. The base model now comes with 512GB of storage instead of 256GB, which feels much more practical for modern use. On top of that, the M5 uses a faster SSD controller, so opening large files, transferring data, and launching apps happens noticeably quicker. If you need a lot of space, you can even configure the M5 up to 4TB, something that was never possible on previous Air models.

MacBook Air M5 vs M4: Difference in Battery Life

Battery life is rated the same on paper for both laptops, up to 18 hours of video playback and 15 hours of web browsing. The battery itself hasn’t changed, but the M5’s newer chip design is a bit more efficient when handling background AI tasks. In real-world daily use, though, you’ll likely see very similar battery performance between the two.

What is the difference in MacBook Air M4 vs MacBook Air M5

While both laptops look nearly identical on the outside, the main differences lie in internal performance, storage, and connectivity upgrades. Apple retained the same design, display, and battery life, but introduced meaningful improvements in the newer model.
