Apple is said to be developing its own 5G chip for future iPhones, but Qualcomm is expected to remain the modem supplier for all iPhone 15 and iPhone 16 models, suggesting that Apple’s chip won’t hit the market until at least 2025.

Haitong International Securities analyst Jeff Pu said in a research note Friday that he expects iPhone models released in 2024 to use the as-yet-unannounced Qualcomm Snapdragon X75 modem. Like the Snapdragon X70, the X75 is expected to be manufactured using TSMC’s 4nm process, which will help improve energy efficiency.

In June, TF International Securities analyst Ming-Chi Kuo stated that Qualcomm will remain the sole supplier of 5G modems for new iPhone models in 2023, as Apple has failed to complete development of its own replacement chip. At the time, Kuo said he believed Apple would continue to develop its own 5G chip, but did not specify a timeframe for when the chip would be ready for use in the iPhone.

All four iPhone 15 models are expected to feature the latest Qualcomm Snapdragon X70 modem, announced in February. Like the Snapdragon X65 modem in iPhone 14 models, the X70 theoretically up to 10 Gbps with newly added AI features for higher average speeds, improved coverage, better signal quality, lower latency and up to 60% more energy efficiency. Supports download speeds.

Overall, while initial reports claim that Apple’s own 5G modem could launch on iPhones as early as 2023, the transition could take at least a few more years.
