This is when Apple may start mass production of the iPhone SE 4

Apple suppliers are set to begin mass production of the fourth-generation iPhone SE soon. According to supply chain analyst Ming-Chi Kuo, the upcoming less-expensive iPhone model is set to go into mass production in December. If this prediction is to be true, it suggests that the new iPhone SE is on track for an early 2025 release, likely in March or April.
In his blog post, Kuo suggested that Apple suppliers are expected to produce nearly 8.6 million units of the new iPhone SE in the first quarter of next year.
