According to Kuo, the biggest beneficiary of this decision will be Qualcomm, which is currently the exclusive supplier of 5G modems for Apple smartphones and will likely continue to be such until at least 2024.
Kuo did not say why Apple delayed the fourth-generation iPhone SE indefinitely, or whether the performance of its own 5G chip had anything to do with the decision. For the better part of a decade, Apple has been trying to reduce its reliance on Qualcomm. In 2019, the companies ended their bitter patent feud and signed a "multi-year" agreement on wireless chips supply. However, a few months later, Apple bought most of Intel's mobile modem business. Then, in late 2020, the company said it was working on its own data chip, but there's been little news about the project since then.
