iPhone 18 Pro Max Battery Trade-Off Leaked

The iPhone 18 Pro Max is rumored to feature a 5,500 mAh battery, delivering nearly 10% longer life, but will measure around 9mm thick and weigh approximately 240 grams. That makes it 0.25mm thicker and 7 grams heavier than the iPhone 17 Pro Max, with a new stainless steel vapor chamber also contributing to the added bulk.
