ecent leaks from industry insider Majin Bu point to a 2,800–2,900 mAh battery inside the upcoming iPhone 17 Air, a sharp drop from the 3,561 mAh cell in the current iPhone 16—a design trade-off aimed at delivering Apple’s thinnest phone ever. The leak appears to use a steel-framed battery that enables high energy density in a thinner chassis. (Source: El País Smart Life)
Why This Matters: Design vs. Endurance
Apple is reportedly targeting a phone thickness of just 5.5 mm, aiming for a sleek form factor that challenges rivals like Samsung’s Galaxy S25 Edge. While battery capacity drops, Apple may rely on silicon-carbon cell technology and iOS 26 battery optimization features to maintain acceptable real-world usage. According to Tom’s Guide, leaks suggest users could get less than a full day’s worth of use—especially under heavy usage—putting Apple’s efficiency claims to the test.
Rumors & Confirmation: Ultra-Thin Specs Still Up for Debate
Speculative data from TechRadar and other sources reinforce the narrative: a 2,800 mAh battery in the iPhone 17 Air reflects engineering priorities focused on sleekness, though critics question if reduced battery life will outweigh the aesthetic leap. (Insights via TechRadar report)
