The MacBook Air 15 delivers a superb blend of strong performance, epic battery life, and a sleek design in its class. As our testing revealed, the new M3 chip powering this laptop brings notable gains over the previous M2 chip, resulting in lightning-fast speeds for productivity and entertainment MacBook Air 15.

In our real-world use, applications and workflows were handled smoothly on the MacBook Air 15 without any lag or pauses. Content creation tasks like photo editing ran superbly. Advanced operations involving intense apps were still doable, showing this laptop’s flexibility despite its thermal limitations compared to the fan-powered MacBook Pro.

In this blog post, We will share our findings on the MacBook Air 15’s overall performance, display, design, battery life and whether it makes a compelling case as a do-it-all yet lightweight laptop.

Excellent Performance From the Apple MacBook Air 15

M3 Chip

The MacBook Air 15-inch is powered by the new M3 chip which provides excellent performance. According to benchmark tests, the M3 chip outperforms the previous M2 chip and offers up to 60% faster performance. In real-world use, applications and workflows are handled smoothly without lag.

Gaming

While not targeted as a gaming laptop, the M3 chip allows playing games like Death Stranding at average frame rates of 28fps at the highest settings. For smooth 60fps gaming, the resolution needs to be scaled down to HD. The integrated 10-core GPU can handle graphics-intensive games well at 1080p resolution.

AI Capabilities

With the 16-core Neural Engine, the MacBook Air is well-suited for advanced AI tasks like generating images using apps like DiffusionBee. Cloud-based AI services like Copilot can also be leveraged. However, cloud services may take longer than local AI tools for complex queries.

Sleek Design of the Apple MacBook Air 15

Stunning Display

The 15.3-inch Liquid Retina display offers users an expansive and immersive viewing area compared to the 13-inch model. At a resolution of 2880 x 1864 pixels, the content appears incredibly detailed and vivid. The taller 16:10 aspect ratio provides even more vertical screen real estate for productivity tasks like working with documents and spreadsheets.

Durable Aluminium Construction

Made from 100% recycled aluminium, the MacBook Air 15 chassis exudes sturdiness despite a remarkably thin 0.45-inch dimension. Its flat unibody design features gently tapering curves for comfort. Measuring 13.4 x 9.35 inches, the MacBook Air 15 expands its predecessor’s screen real estate substantially while retaining an agreeably compact footprint.

Sleek Midnight Colour

One of the most appealing design aspects is the midnight finish, which resembles a lustrous black. Through anodization, this colour variation is optimized to naturally repel fingerprints and smudges. Over time, it maintains a pristine look without the need for frequent cleaning.

Minimal Port Selection

Despite the larger size, only two Thunderbolt 4 ports are offered for connectivity. While limiting, these high-performance ports support data transfer, dual 4K displays, and up to 40Gbps throughput. Charging occurs via the dedicated MagSafe 3 port, keeping USB-C ports unblocked.

Battery Life on the MacBook Air 15

Long-lasting Power

The MacBook Air 15 truly lives up to its namesake with excellent battery runtimes. In our lab tests following continuous web browsing, the laptop surpassed 15 hours of use on a single charge.

In real-world use over multiple days, the battery was more than capable of powering the MacBook Air 15 through productive workdays involving heavy multitasking between web apps and productivity software.

Apple promises a max of 18 hours for video playback to ring true. The MacBook Air 15 comes very close to achieving that lofty number. In contrast, competing Windows laptops struggle to crest 10 hours under similar test conditions.

Rapid Charging Convenience

With its included 67W USB-C Power Adapter, the MacBook Air 15 can fast charge when the battery runs low. Just 30 minutes plugged in restored over 50% power, allowing swift top-ups during coffee breaks.

The ability to charge with compact USB-C power bricks and batteries as an alternative to Apple’s bulkier adapter provides welcome flexibility for on-the-go users.

Market-leading endurance

In battery testing, the MacBook Air 15 consistently outlasted rival Windows machines. For example, it stayed powered over 5 hours longer than the top-of-the-line Dell XPS 16 under intensive web browsing workloads.

Even activities like mid-tier gaming failed to rapidly deplete the large battery. Pushing the processor and graphics with titles like Death Stranding still left ample reserves to last all day.

Key Differences between the 13-inch and 15-inch MacBook Air Models

Spacious Screen on the 15-inch MacBook Air

With its 15.3-inch panel, the MacBook Air 15 offers a significantly larger viewing area than the 13.6-inch 13-inch model. Content, spreadsheet cells, and app windows appear more spacious. Two full windows can be easily used side by side.

Increased Size and Weight of the 15-inch MacBook Air

Weighing 0.6 lbs more, the MacBook Air 15 has a larger and slightly heavier design. It nearly reaches the size and weight of pro-level notebooks but is still quite portable. Those who prioritize ultimate lightness may prefer the 13-inch model.

Enhanced Speakers on the 15-inch MacBook Air

A six-speaker system delivers great stereo separation and richer bass. The 13-inch model only features four speakers, though both support spatial audio. For multimedia lovers, the 15-inch model produces better sound.

Comparable Processor Performance

Being equipped with the same M2/M3 silicon, performance does not differ much between models. The larger chassis provides marginally better cooling but no major advantage under regular workloads.

Similar Pricing

The 13-inch MacBook Air starts at $1,099 while the 15-inch is $1,299. For the same specifications, the 15-inch model commands around a $200 premium. This represents good value for money given its larger screen and speakers.

Overall, the MacBook Air 15 presents a worthwhile trade-off of size, weight, and screen real estate for productivity-minded users. Its bigger display enhances the experience significantly.

Conclusion

Apple MacBook Air 15-inch (M3) delivers a super combination of potent M3 processor performance, a generous 15.3-inch display, excellent build quality, and over 15 hours of battery life in a thin-and-light design. It addresses the long-standing need for a larger-screened model accessible to mainstream buyers rather than pro users.

Priced competitively against Windows machines, this MacBook Air greatly expands the Mac experience in an all-day laptop optimized for productivity and entertainment. Power users seeking more graphics capabilities or longer battery life may prefer a MacBook Pro, but the Air 15-inch fulfils the requirements of most users seeking more screen area without the cost or size of a pro-level machine. It achieves the coveted balance of screen, power and portability.
