With the second half of 2026 approaching, Apple is said to be gearing up to introduce the iPhone 18 series in September. The Cupertino-based tech giant is expected to launch the iPhone 18 Pro and Pro Max models this year, while the vanilla iPhone 18 could debut in 2027. But even though the launch is still several months away, the demand for the iPhone 17 series seems to have cooled off. As such, a tipster has suggested that Apple has reduced its production plans for the iPhone 17 lineup by around 15 percent.
