Apple MacBook Air M4 2026 Review: Unleashing Apple Intelligence

After years of testing laptops that promise the world but deliver thermal throttling and pathetic battery life, I approached the Apple MacBook Air M4 2025 with healthy scepticism. Apple claims up to 18 hours of battery life and groundbreaking performance in a fanless design. I’ve spent three weeks putting this through proper mobile worker abuse – coffee shops with glare, trains with dodgy Wi-Fi, and enough video calls to make any laptop weep. Here’s what actually matters.

What impresses me most is the thermal design. This is a fanless laptop that doesn’t throttle under sustained load. I ran Cinebench R23 for 30 minutes straight, and performance remained consistent throughout. That’s remarkable engineering, and it means you’ll never hear fan noise during video calls or when exporting photos.

Colour accuracy is exceptional out of the box. I measured 100% sRGB coverage and 89% DCI-P3, with Delta E values below 1.5 for most colours. For photo editing, this means you can trust what you see on screen. Text rendering is razor-sharp thanks to the high pixel density (224 PPI), making this brilliant for long writing sessions.

The only limitation is the 60Hz refresh rate. If you’re coming from a 120Hz display, scrolling will feel slightly less fluid. It’s not a dealbreaker for productivity work, but gamers and those who’ve grown accustomed to high refresh rates will notice. Apple reserves ProMotion (adaptive 120Hz) for the MacBook Pro line, which feels like an arbitrary limitation given the M4’s capabilities.

In Cinebench R23 multi-core testing, I recorded 14,850 points – a significant jump over the M3’s 12,100 points. Single-core performance reached 2,680 points, which translates to snappy application launches and responsive UI interactions. The 10-core GPU scored 38,200 in Geekbench Metal, making this capable of light gaming and GPU-accelerated workflows.

What’s remarkable is the consistency. I’ve tested countless Windows laptops that post impressive benchmark scores but then throttle within minutes during real-world use. The MacBook Air M4 maintains performance because Apple has engineered the thermal solution properly. The aluminium chassis acts as a giant heatsink, spreading heat evenly rather than creating hotspots. The palm rest stays cool even during extended rendering tasks.

For context, this outperforms Intel Core i7 laptops that cost similar money and require noisy fans. If you’re doing professional creative work, the MacBook Air M4 handles it better than most Windows machines twice its thickness. The only time you’ll hit limits is with sustained 8K video editing or heavy 3D rendering – tasks that really demand a MacBook Pro with active cooling.

I tested video playback by looping a 1080p YouTube video at 50% brightness with Wi-Fi connected. The laptop ran for 17 hours and 12 minutes before dying. Web browsing at 150 nits brightness (comfortable for indoor use) lasted 14 hours and 38 minutes. These aren’t lab conditions – this is with background apps running and notifications pinging.

For comparison, the Lenovo IdeaPad Slim 3 I tested last month managed 7 hours of mixed use. The Dell XPS 13 with Intel Core Ultra chips? About 9 hours. The MacBook Air M4’s efficiency is in a different league, and it’s down to the tight integration between Apple Silicon and macOS.

The included 67W USB-C charger is compact and supports fast charging. I measured 0-50% in 35 minutes, which is brilliant when you need a quick top-up between meetings. You can also charge via any USB-C port, and the laptop supports charging from portable power banks – genuinely useful for long train journeys.

The build quality is exceptional. The entire chassis is machined from recycled aluminium, and there’s zero flex anywhere – not in the lid, not in the keyboard deck. I’ve tested £300 laptops with plastic chassis that creak when you pick them up. This feels like a precision instrument. The hinge is perfectly balanced, allowing one-handed opening without the base lifting off the desk.

Apple’s attention to detail shows in small touches. The rubber feet are substantial enough to prevent sliding but don’t add unnecessary thickness. The ports (two Thunderbolt 4 on the left, MagSafe 3 charging, and a 3.5mm headphone jack on the right) are positioned sensibly. MagSafe charging is brilliant – it magnetically attaches and will safely disconnect if you trip over the cable, rather than sending your laptop flying.

Touch ID is integrated into the power button and works flawlessly for unlocking the laptop and authorising purchases. It’s faster and more reliable than Windows Hello facial recognition in my experience.

The trackpad deserves special mention because it’s genuinely the best I’ve used on any laptop. At 116mm wide, it’s enormous, giving you plenty of space for gestures. The Force Touch technology uses haptic feedback to simulate clicks, which means it works consistently across the entire surface. Windows laptops with physical click mechanisms only register clicks in the bottom half of the trackpad – this responds perfectly whether you click at the top or bottom.

Multi-touch gestures are smooth and responsive. Three-finger swipe to switch between apps, pinch to zoom, two-finger scroll – everything works intuitively. Palm rejection is perfect; I never had accidental cursor movements whilst typing. If you’ve suffered through terrible Windows laptop trackpads (and I’ve suffered through many), this will feel revelatory.

The three-microphone array with directional beamforming is impressive. On Teams calls, colleagues commented that my voice sounded clear even with background noise. The mics effectively suppress keyboard typing sounds and ambient chatter, which is brilliant for working in coffee shops.

Spatial Audio with head tracking works when watching supported content, creating a convincing surround sound effect. It’s a nice feature for films, though I wouldn’t rely on it for critical listening. The 3.5mm headphone jack supports high-impedance headphones and sounds excellent – Apple hasn’t skimped on the DAC.

Notification summaries condense multiple alerts into digestible chunks, which reduces interruption fatigue. Siri is more contextually aware and can handle follow-up questions better than before. However, these features feel like refinements rather than revolutionary capabilities. Microsoft’s Copilot integration in Windows 11 offers similar functionality.

The privacy-focused approach is commendable. All Apple Intelligence processing happens on-device using the Neural Engine in the M4 chip, meaning your data never leaves the laptop. For professionals handling sensitive information, this is a significant advantage over cloud-based AI services.

However, the Thunderbolt 4 ports are versatile. Each supports 40Gbps data transfer, dual 4K displays or one 6K display, and charging. I connected a Thunderbolt dock and ran two external monitors, Ethernet, and multiple USB devices through a single cable – that’s the advantage of Thunderbolt’s bandwidth.

Wi-Fi 6E delivers fast wireless speeds with compatible routers, and Bluetooth 5.3 provides reliable connections to peripherals. I experienced no dropouts with wireless headphones or mice during testing.

For Windows users, the Dell XPS 13 Plus offers comparable build quality and a gorgeous OLED display option. However, battery life is significantly worse (around 9 hours mixed use), and the keyboard is divisive – the touch-sensitive function row frustrates many users. It’s also more expensive at £1,299 for similar specs.

The MacBook Air 15-inch M4 is worth considering if you want more screen space. At £1,499, it’s £200 more but gives you a 15.3-inch display in a chassis that’s still impressively portable at 1.51kg. The larger battery provides even longer runtime.

Budget-conscious buyers should look at the Lenovo IdeaPad Slim 3 or HP Ryzen 3 laptops around £400-500. You’ll make significant compromises on build quality, display, and battery life, but they’re adequate for basic productivity work.
