A week with the iPhone 18 Pro: the smaller model no longer trails the Pro Max

ZDNet's week-long testing found the iPhone 18 Pro now matches the Pro Max on battery life and thermals, thanks to the 2nm A20 Pro, a larger battery and a bigger vapor chamber. Both models gained roughly 16 grams, and darker finishes attract fingerprints.

• The 2nm A20 Pro offers 50% more memory bandwidth than the A19
• iPhone 18 Pro battery life matches last year's iPhone 17 Pro Max
• Both models gained about 16 grams from the battery and cooling system
• Dark finishes like Burgundy and Black show fingerprints easily
