Apple MacBook Air M5: First Look and Early Testing

Apple's M4 MacBook Air landed in our lab this week, and the first round of numbers tells a clear story: this is the largest generational leap the Air line has seen since the jump from Intel to Apple Silicon. Battery life in our real-world test hit 14.2 hours — a figure that makes the Air competitive with machines twice its price in the productivity ultrabook category. Multi-core performance climbed 18% over the M3, and the new 12 MP Center Stage camera is a genuine upgrade for anyone who spends part of their day on video calls. Full review coming in two weeks; here is everything we know so far.

MacBook Air M5

Apple

Battery life hit 14.2 hours in our initial test — confirming Apple's '18 hours video playback' claim translates to 14+ hours of real work. The M4 scored 18% higher than the M3 in multi-core benchmarks.

What changed from the M3

The M4 chip moves to a second-generation 3-nanometer process node, the same die shrink that debuted in the iPad Pro last year. Apple claims a 25% improvement in CPU performance per watt and a 35% jump in GPU throughput compared to the M3. In our early benchmarks, those claims hold up — and in some workloads, they understate the gains.

The physical chassis is almost unchanged. Apple kept the 13.6-inch Liquid Retina display at 500 nits peak brightness, the same MagSafe charging, and the same two Thunderbolt ports (now upgraded to Thunderbolt 4, which doubles bandwidth from 20 Gbps to 40 Gbps). The keyboard, trackpad, and speaker system are carryovers. The weight remains 2.7 pounds.

The meaningful exterior change is the camera: the FaceTime module jumps from 1080p to a 12 MP sensor with Center Stage, the dynamic framing feature that keeps you centered during video calls even if you move around. In our initial Zoom tests, the image quality was noticeably sharper with better low-light performance — fine detail in background bookshelves stayed crisp at indoor office lighting (around 300 lux) where the M3 model softened into noise.

How we tested

Our laptop evaluation protocol runs four parallel tracks: battery life, compute benchmarks, thermal performance, and daily-use panel testing. We purchased the M4 Air at retail from Apple's website — base configuration with 16 GB RAM and 256 GB SSD — for $1,099.

Battery life. We run our standardized real-world workload test: 30 browser tabs across Safari, Chrome, and Firefox (a mix of static articles, YouTube at 1080p, Google Docs with live collaboration, and a Figma board), Slack with three active workspaces, a Zoom call for 45 minutes, a spreadsheet with 12,000 rows of VLOOKUP-heavy formulas, and Spotify streaming in the background. Screen brightness is locked at 150 nits. Wi-Fi stays connected. We run this test twice and average the results. The M4 Air delivered 14.2 hours and 13.8 hours — a 14.0-hour average.

For context, the M3 Air averaged 12.1 hours on the same test. The M2 Air averaged 10.8 hours. The 14-hour mark puts the M4 Air in a class where most users will never need to carry a charger for a full workday.

Compute benchmarks. Geekbench 6 single-core: 3,842 (M3: 3,128). Geekbench 6 multi-core: 15,214 (M3: 12,087). Cinebench 2024 multi-core: 628 (M3: 531). Our Lightroom Classic export test — 100 RAW files from a Sony A7R V, each with basic edits applied, exported as full-resolution JPEGs — completed in 2 minutes 41 seconds, down from 3 minutes 18 seconds on the M3.

Thermal performance. The Air is fanless, so thermal throttling matters. We ran Cinebench in a loop for 30 minutes. The M4 Air sustained 92% of its peak multi-core score after 30 minutes — a measurable improvement over the M3, which dropped to 85% under the same conditions. The bottom of the chassis reached 41°C (106°F), warm but not uncomfortable on a lap.

Display and speakers

The 13.6-inch Liquid Retina display carries over from the M3 model — 2560 × 1664 resolution at 224 pixels per inch, 500 nits peak brightness, P3 wide color gamut, True Tone. It remains one of the best laptop displays in its price class, though the lack of ProMotion (120 Hz adaptive refresh) is increasingly noticeable as competitors adopt high refresh rates. Dell's XPS 13 Plus and the ASUS Zenbook 14 OLED both offer 120 Hz panels at similar price points. In daily use, the 60 Hz panel is perfectly functional for productivity — the difference shows up primarily in scrolling smoothness and cursor tracking.

The six-speaker sound system with Spatial Audio support is surprisingly capable for a laptop this thin. Music playback has genuine stereo separation, and vocals in video calls are clear even at maximum volume without distortion. Bass remains the limiting factor — there is no substitute for physical driver size — but for a 2.7-pound machine, the audio output punches above its weight class.

Who this is for

The M4 Air is the right laptop for anyone whose workday revolves around a browser, a communication tool, and a document editor — which, based on our reader surveys, describes about 70% of the professionals in our audience. The 14-hour battery life eliminates charger anxiety for all-day use. The M4 chip handles everything up to moderate photo editing and light video work without breaking a sweat.

It is not the right machine for sustained creative workloads. If you regularly export 4K video in Final Cut Pro, render 3D scenes in Blender, or compile large codebases, the fanless design will throttle performance over time. The MacBook Pro 14-inch with M4 Pro starts at $1,999 and adds active cooling, a ProMotion display, and additional Thunderbolt ports — worth the premium for heavy workloads.

Compared to the Windows ultrabook field, the Air's closest competitors are the Dell XPS 13 Plus ($1,199) and the Lenovo Yoga Slim 7i ($1,049). Both offer OLED display options and comparable build quality, but neither matches the Air's battery life. The XPS 13 Plus averaged 9.8 hours in our testing; the Yoga Slim 7i hit 10.4 hours. If battery life is your top criterion — and for a portable machine, it probably should be — the Air wins by a significant margin.

What we still need to test

Our full review will cover several areas we have not yet evaluated. The Thunderbolt 4 upgrade needs external display and hub testing — we want to confirm that dual-monitor support (up to two external displays) works reliably with third-party docks. We are also running our 90-day durability assessment, tracking hinge stiffness, keyboard key travel consistency, and chassis flex over time. Our panel will use the machine as a daily driver for a minimum of three weeks before we finalize scores.

We will also test the 15-inch M4 Air, expected in the same configuration, to determine whether the larger chassis and bigger battery translate to proportionally longer battery life or if the larger display offsets the gain. Historical data from the M3 generation suggests the 15-inch model adds approximately 1.5 hours of battery life in our workload test.

Early verdict

After one week with the M4 MacBook Air, the early data points strongly in one direction: this is the best general-purpose laptop available under $1,500. The 14-hour real-world battery life is class-leading. The M4 chip delivers enough performance for everything short of sustained creative rendering. The build quality remains the benchmark for the category. The only notable absence is a high-refresh-rate display — a feature that competitors are starting to offer and that we expect Apple to address in a future revision.

We are withholding a final score until our multi-week panel testing is complete. Based on early results, the M4 Air is tracking toward a 9.4 or higher — which would make it the highest-scoring laptop in our current database. Full review publishes August 30.

Gold Tested Score: Battery (early): 9.8/10, Performance (early): 9.3/10, Display: 9.5/10, Build: 9.6/10, Keyboard: 9.2/10. Overall: TBD (testing in progress)

The bottom line

We tested these products to find the one worth recommending, and the MacBook Air M5 made the decision simple. Top marks in performance and build quality, zero significant weaknesses.

Performance benchmarks in context

Raw benchmark numbers require context to translate into practical user experience. The M4 chip's 10-core CPU delivers single-core performance approximately 25 percent faster than the M2 and 10 percent faster than the M3 — an improvement that manifests as snappier app launches, faster web page rendering, and more responsive multitasking. Multi-core performance improvements are larger (30 to 40 percent over M2) and relevant for workloads that parallelize: video export, photo batch processing, code compilation, and large spreadsheet calculations.

The real-world translation: Exporting a 10-minute 4K video in Final Cut Pro takes approximately 4 minutes on M4 versus 5.5 minutes on M2 — meaningful for content creators who export multiple times daily, negligible for users who export once a month. Compiling a medium-sized Xcode project (50,000 lines of Swift) completes in approximately 45 seconds versus 65 seconds on M2. For the majority of users (web browsing, email, document editing, video calls), the M4 feels identical to the M3 in daily operation — the performance ceiling of these tasks was already met by earlier Apple Silicon generations. The M4's value for light-use consumers lies not in speed but in efficiency: the same tasks consume less power, extending battery life by 1 to 2 hours compared to the M2 Air.

Memory considerations: The base configuration ships with 16 GB of unified memory — sufficient for typical productivity workloads, web browsing with 20 to 30 tabs, and light creative work. Upgrading to 24 GB ($200 premium) is justified for users who regularly run virtual machines, work with large Photoshop or Illustrator files, or maintain complex development environments with Docker containers. The 32 GB option ($400 premium) targets professional workflows: simultaneous 4K video editing and color grading, machine learning model training, and heavy database work.

Configuration advice

The base 256 GB SSD is the one spec worth upgrading at purchase. Unlike RAM, which Apple unified into the M4's system-on-chip architecture and made non-upgradeable, storage cannot be expanded after the fact — there is no SD card slot, no user-accessible SSD bay, and external drives add bulk that defeats the Air's portability. In our testing, the 256 GB model left roughly 190 GB of usable space after macOS and pre-installed apps. For a machine expected to serve as a primary computer for 4-5 years, that margin disappears quickly once you account for application caches, Xcode or creative tool libraries, and offline media. The upgrade to 512 GB costs $200 at purchase — steep per-gigabyte, but it eliminates the most common long-term complaint among MacBook Air owners. The 16 GB unified memory in the base model, by contrast, is sufficient for the productivity workloads this machine targets. Our benchmark testing showed no meaningful performance difference between 16 GB and 24 GB configurations in browser-heavy, document-editing, and even moderate Lightroom workflows. Save the RAM upgrade for Pro buyers running sustained multi-app creative pipelines.
