May 18, 2025 — A new supply chain leak has revealed critical specifications about Apple’s upcoming ultra-slim smartphone, the iPhone 17 Air, including its battery capacity and overall weight — and the details have sparked mixed reactions among tech enthusiasts.

According to the leak, the iPhone 17 Air will come in at just 5.5mm thickness, making it one of the thinnest iPhones ever. However, that slim profile appears to come at a cost — a 2,800mAh battery, significantly smaller than competitors like the Samsung Galaxy S25 Edge, which houses a 3,900mAh unit in a similar form factor.
⚡ Smaller Battery, Bigger Questions
The 2,800mAh capacity has already raised eyebrows in the industry, with many questioning whether it will be able to deliver a full day’s battery life in 2025’s demanding app and connectivity environment.
That said, Apple could implement new high-density battery TECHNOLOGY, which may boost effective capacity by 15–20%, potentially offsetting the smaller size.
⚖️ Lightweight Design
The leak also reveals that the iPhone 17 Air will weigh just 145 grams, notably lighter than Samsung’s Galaxy S25 Edge despite both phones sporting similarly large displays. This further points to Apple’s design focus on portability and aesthetics, even if it means making trade-offs in battery performance.
🧠 AI Battery Optimization Rumored
While one theory speculates that Apple is deliberately limiting battery capacity to promote Smart Battery Case sales, another report suggests the company may integrate AI-powered battery management in iOS 19. This system would optimize energy consumption based on user behavior and app usage, potentially extending daily performance without increasing battery size.
📱 What to Expect Next
Apple is expected to unveil the iPhone 17 lineup later this year, and the Air model is positioned as the company’s thinnest and lightest flagship yet. If these leaks prove accurate, it will be interesting to see how Apple balances performance, design, and power efficiency — and whether users will accept a thinner iPhone at the expense of battery longevity.
