iPhone 18 Pro Max vs iPhone 18 Pro: Two exclusive features

Today Apple introduced iPhone 18 Pro and Pro Max, its latest flagship models. While each Pro model is largely identical, there are two exclusive new advantages—one for each model. #1: iPhone 18 Pro has C2 modem for cellular, while iPhone 18 Pro Max uses Qualcomm Apple began transitioning its products to in-house cellular modems in early 2025 with the iPhone 16e. First it offered a C1 modem, then the C1X followed in the iPhone Air last fall. Now Apple has introduced the next-generation C2 modem. It’s available in iPhone Duo and iPhone 18 Pro, but curiously is absent from the iPhone 18 Pro Max. Per Apple’s technical specs page, C2 and the iPhone 18 Pro Max’s Qualcomm modem offer comparable specs. They both support mmWave in the US, for example. But Apple-designed modems do have the benefit of unlocking some exclusive benefits, which Pro Max users will miss out on. #2: iPhone 18 Pro Max has much bigger battery gains than iPhone 18 Pro iPhone 18 Pro and Pro Max are both improving in the battery department this year. But as leaks previously indicated, Apple reserved much larger gains for the Pro Max model.
