Regulatory Filings Hint at Larger iPhone 18 Pro Batteries Across Regions

Chinese regulatory filings list battery capacities for the iPhone 18 Pro and iPhone 18 Pro Max: the Pro is rated at 4,056 mAh in China and 4,288 mAh in the U.S., while the Pro Max shows 5,391 mAh in China and 5,567 mAh in the U.S.—each about 0.5 Ah higher than the previous gen. The listings also enumerate battery models (S2232/2233 for the Pro; 2235L/2235 and 2236L/2236 for the Pro Max) with up to 21.751 Wh and a 4.520 V charge limit, valid through mid-2031. The region discrepancy reflects the SIM tray vs eSIM difference. Apple is 예상 to launch these models in September alongside a foldable iPhone, with spec rumors including a smaller Dynamic Island and camera/chip upgrades.
