Summary
iFixit’s teardown found the North American iPhone 18 Pro carries a 4,288mAh battery and the Pro Max 5,567mAh, giving Apple’s new phones their first disclosed capacity figures.
That is a 1% increase for the Pro versus the iPhone 17 Pro’s 4,252mAh battery and a 9.41% jump for the Pro Max from 5,088mAh, though battery-life gains were uneven in testing.
Tom’s Guide measured the iPhone 18 Pro at 16 hours 17 minutes, up about an hour from the 17 Pro, while the Pro Max reached 18 hours 27 minutes, only about 33 minutes longer than its predecessor.
EU listings point to smaller batteries — 4,056mAh for the iPhone 18 Pro and 5,391mAh for the Pro Max — likely reflecting hardware differences such as physical SIM slots instead of eSIM-only designs.
Apple also raised iPhone 18 Pro battery replacement pricing to $129 plus tax, $10 above the iPhone 17 Pro, after increasing base 256GB model prices by $100.
