iPhone 18 Pro Max tipped to gain a massive battery boost
A leaker citing regulatory filings suggests the iPhone 18 Pro Max will have a significantly larger battery than the iPhone 17 Pro Max (about 5,391mAh in China and 5,567mAh in the U.S.), with the iPhone 18 Pro showing 4,056mAh (China) and 4,288mAh (U.S.). The numbers are unverified and may be affected by factors like the SIM tray. If confirmed, this could translate to roughly a 10% battery capacity increase and longer life, though actual performance depends on chips, display, and optimizations. The devices are expected to debut in early September, alongside a foldable reportedly named iPhone Ultra.
