Overview

  • The leak, which remains unverified, comes from Weibo tipster Instant Digital and claims the iPhone 17 Pro Max will feature an approximately 5,000 mAh battery, making it the largest cell ever in an iPhone.
  • That figure represents nearly a 10% increase over the current iPhone 16 Pro Max’s 4,676 mAh cell.
  • Industry analysts predict that, paired with the A19 Pro chip and iOS 26 optimizations, the new cell could deliver around 35 hours of runtime.
  • Early design sketches and reports suggest Apple will adopt a slightly thicker and heavier chassis to accommodate the larger battery.
  • Apple has neither confirmed the battery capacity nor the structural changes, and official details are expected at its September 2025 iPhone unveiling.
