iPhone 18 Pro Clocks Half the 5G Speed of Pro Max in Early Test

A Reddit user compared the iPhone 18 Pro and 18 Pro Max at the same location and time: the Pro Max hit 279 Mbps down and 4.11 Mbps up, while the Pro managed 140 Mbps and 2.54 Mbps. The gap stems from different modems — in the U.S., the Pro Max uses a Qualcomm chip while the Pro uses Apple's new C2 modem.
