iPhone 18 Pro Max Filings Show 5,567mAh Battery, Nearly 10% Above iPhone 17 Pro Max

Q: With its largest battery ever, is Apple's iPhone 18 Pro Max set to end the battery life debate with Android?

Probably not, but it could narrow the gap sharply. The filings point to the iPhone 18 Pro Max getting Apple’s biggest battery yet, with the U.S. model listed at 5,567mAh and the China model at 5,391mAh. That is a meaningful jump from the iPhone 17 Pro Max and, on paper, puts Apple in the same range as or above many premium Android flagships. What matters more than capacity alone is the full power system. The iPhone 18 Pro Max is also expected to use a more efficient 2nm A20 Pro chip, Apple’s C2 modem, and iOS 27 optimizations. If those reports hold, Apple could deliver a noticeable real-world battery gain, especially in standby, video, and mixed daily use, where iPhones already tend to perform well relative to their battery size. Still, this is unlikely to “end” the debate with Android. Android makers continue to compete with large batteries, fast charging, adaptive refresh controls, and aggressive power management. Battery life also varies by network conditions, display brightness, camera use, gaming, and background apps, so raw mAh does not settle the issue by itself. There is also an important caveat: these figures come from regulatory filings and leaks, not Apple’s official battery-life claims or independent testing. Until reviewers compare the iPhone 18 Pro Max against top Android phones in standardized tests, the safest reading is that Apple looks poised to become more competitive on endurance, not to settle the argument permanently.

Chinese regulatory filings point to a 5,567mAh battery for the U.S. iPhone 18 Pro Max and 4,288mAh for the iPhone 18 Pro ahead of Apple's expected September launch.
That would give the Pro Max its biggest year-over-year battery jump in this cycle—nearly 10% above the iPhone 17 Pro Max—while the Pro model would rise by less than 1%.
A thicker Pro Max chassis previously rumored for the iPhone 18 line could help accommodate the larger cell, even as the two Pro models are otherwise expected to stay closely matched.
Both phones are still rumored to share the same main 48-megapixel Fusion camera with variable aperture, leaving battery life—not camera hardware—as the standout differentiator.
