Apple is testing its proprietary 5G modems, aiming for full integration into its chipsets by 2028. While the current C1 modem is less efficient than Qualcomm's, future models may enhance performance and reduce dependency on external suppliers,

Phone 17 5G modems will be made by MediaTek, as Apple moves away from Qualcomm. Future iPhones will use Apple's solutions instead.

Apple and Qualcomm's relationship has been strained for a decade and the iPhone 16e C1 chip is Apple's first move to cut ties once and for all.
