iPhone 17 Air Battery Leak Reveals Just 2900mAh Capacity – Ultra-Thin Design Prioritized

A recent leak from X-platform tipster Majin Bu has revealed the iPhone 17 Air battery specifications. According to the leak, Apple’s thinnest iPhone yet will come with a mere 2900mAh battery, raising concerns about its real-world endurance.

The leaked photo shows a metal-shell battery, likely designed to fit into the ultra-slim 5.5mm chassis while enhancing internal durability. However, this comes at a cost—especially when compared to other 2025 flagships:

  • Xiaomi 15 – 5400mAh
  • vivo X200 Pro Mini – 5700mAh
  • OPPO Find X8s – 5700mAh
  • OnePlus 13T – 6260mAh
  • Galaxy S25 Edge – 3900mAh

With such a low battery capacity, daily charging may not be enough for many users. Sources suggest Apple might reintroduce its Smart Battery Case to improve battery life.

Expected Price and Release Timeline

As per Mark Gurman from Bloomberg, the iPhone 17 Air could start at $899 (approx. ₹74,000 or ¥6483). It is likely to launch in September 2025 alongside the rest of the iPhone 17 series.

The iPhone 17 Air stands out with its ultra-slim form and premium titanium build, but the 2900mAh battery might prove to be a major drawback. With Android rivals offering significantly larger batteries in similar-sized devices, Apple’s battery optimization and accessory support will be key to its success.Whether the iPhone 17 Air will attract style-first buyers or fall short on practicality remains to be seen.
