Apple has recently released a new MagSafe Battery—available for $99—specifically designed for its sleek, new iPhone Air and incompatible with other models like the iPhone 17 or 17 Pro. The accessory is taller and narrower, matching the iPhone Air’s form factor, though it may interfere with camera placement on other iPhones, and offers up to 40 hours of video playback or an additional 65 percent charge. It supports 12 W wireless charging, and if plugged into a 20 W (or higher) power adapter, can deliver faster passthrough charging. This marks a shift from Apple’s previous MagSafe accessories, which offered broader compatibility.

Key Takeaways
– Apple is going niche by releasing a MagSafe battery that only fits the ultra-thin iPhone Air—suggesting design priority over accessory universality.
– Impressive battery extension: up to 40 hours of video playback or a 65% battery boost while retaining a slim profile.
– Charging flexibility: 12 W wireless charging that supports faster passthrough when plugged into a 20 W+ adapter, though still limited compared to MagSafe capabilities on other models.
In-Depth
Apple’s new MagSafe Battery penned as an exclusive companion to the ultra-slim iPhone Air speaks volumes about the company’s renewed focus on seamless design coordination. Priced at $99, this isn’t just another universally compatible accessory—it’s custom-tailored to fit the iPhone Air’s 5.6 mm slim frame and tall-bodied build. The result? A battery that visually complements the phone yet remains incompatible with other iPhone models, likely due to camera bump interference.
Battery-wise, Apple claims it delivers up to 40 hours of video playback or an extra 65% of charge, a solid boon for anyone prioritizing longevity without hauling bulk. It charges wirelessly at 12 W, but those wanting speed can plug it into a 20 W or higher adapter for passthrough charging that benefits both battery and phone. While it offers handy flexibility, this speed still trails behind the faster 20–25 W MagSafe charging seen in the iPhone 17 line.
This accessory reflects a strategic pivot: Apple increasingly sees accessories as part of the product ecosystem rather than add-ons. Tailoring the MagSafe battery to one phone underscores their commitment to a minimalist aesthetic, even at the expense of broader compatibility—a shift from past MagSafe designs meant to function across multiple generations.
For iPhone Air users, this battery may feel like a thoughtful companion—visually and functionally aligned with the device. For iPhone 17 or 17 Pro users, however, it’s clear: look to third-party options, or wait and see. Apple’s message here is subtle yet unmistakable—form can guide function.
