Apple is getting ready to launch its thinnest iPhone ever — the iPhone 17 Air. Sleek, lightweight, and clearly designed to turn heads, it’s already making waves before its official release. But early reports suggest that its ultra-slim design might come at a cost. And for many users, that cost could be battery life.
Ultra-thin, but at what price?
Apple has reportedly pushed the design boundaries with the iPhone 17 Air, making it just 5.5mm thick. That would make it thinner than any previous iPhone, and among the slimmest smartphones ever released. Aesthetically, it’s striking — modern, minimalist, and visually impressive.
But making a device that thin means something has to give. And the first thing to shrink is the battery. According to internal sources, the battery inside the iPhone 17 Air will be smaller than what’s found in other models in the iPhone 17 lineup. That’s expected. But the implications are already raising concerns.
Battery life takes a hit
Preliminary tests indicate that most users will get less screen time on the iPhone 17 Air than on other recent iPhones. Apple reportedly expects only around 60 to 70 percent of users to get through a full day on a single charge. For comparison, most modern iPhones aim for 80 to 90 percent full-day usage under average conditions.
In other words, unless your usage is light — or you’re near a charger most of the time — you might be reaching for that cable well before the end of the day.
Apple’s solution: bring back the Smart Battery Case
To address the power limitations, Apple is reportedly planning to bring back the Smart Battery Case. Last seen with the iPhone 11 and discontinued around the iPhone 12 era, this accessory adds several hours of battery life. But it also adds bulk — which could undermine the whole point of a thin phone in the first place.
The irony isn’t lost on users. Apple builds its thinnest phone ever… and then suggests you attach a thick battery case to make it last longer. Whether people will embrace that trade-off remains to be seen.
Fewer features, slimmer profile
In addition to a smaller battery, the iPhone 17 Air is also expected to scale back on other hardware features. Leaks suggest it will come with just one rear camera, unlike the dual-lens systems on the iPhone 17 and 17 Pro. It may also rely solely on eSIM technology, removing the physical SIM slot entirely. Stereo speakers? Possibly gone too — replaced by a single speaker to save space.
All of these changes appear to be part of Apple’s strategy to keep the device ultra-thin and lightweight. But for users who value versatility and long battery life, these compromises could be a dealbreaker.
Premium price tag, minimalist specs
Despite the reduced features, the iPhone 17 Air won’t be a budget device. Current estimates suggest a starting price around $900. That puts it squarely in the premium tier, which could be a tough sell if the device doesn’t deliver on practical usability.
Apple is expected to unveil the iPhone 17 lineup, including the Air model, during its September 2025 keynote. Until then, consumers are left wondering: is the thinnest iPhone ever really worth the trade-offs?
For those who care more about form than function, the 17 Air might be a dream come true. For others, it could feel like too much sacrifice for too little gain.
