Qualcomm released a statement in September last year confirming that it had renewed its agreement with Apple for three years and would continue to supply baseband chips for iPhones until 2026. There are reports that Apple's self-developed 5G modem, codenamed "Sinope", has poor performance of the prototype, which is not only slow, but also prone to overheating. Later, it was reported that Apple may choose to abandon its self-developed 5G baseband project due to the fact that the long-term efforts have not paid off and there have been many difficulties so far. 
According to WCCFTECH, at Qualcomm's Q1 2024 earnings conference**, CEO Christiano Amon said that the agreement with Apple for iPhone baseband chips** has been extended until March 2027. This more or less confirms the rumors from the side that Apple's self-developed 5G baseband development has encountered great trouble and needs more time to solve. Christiano Amon said he is very satisfied with the current relationship between Qualcomm and Apple, and that extending the partnership means that Qualcomm can continue to enjoy stable revenue in the coming years. Previously, the outside world was worried about Qualcomm's prospects, believing that if Apple can launch its self-developed 5G baseband between the end of 2025 and early 2026 as planned, it will definitely replace Qualcomm's solution in the future, resulting in a huge loss of Qualcomm's revenue.
Apple did not respond to this matter, but the extension of the original agreement has fully explained the problems encountered in the self-developed 5G baseband. While Apple has worked hard to reduce its dependence on Qualcomm through in-house products, it has encountered many obstacles that it has so far been reluctant to admit.
