Multiple reports say Apple could stagger the iPhone 18 lineup release rather than launching all models together. The premium iPhone 18 Pro models are widely cited as having a launch date of September 9, while the timing for the standard (base) iPhone 18 models may be different, with delays mentioned for the non-Pro lineup.
According to these accounts, the “split” approach could mean Pro models go on sale first, followed by base models later. The rationale described across the reporting is that supply or production constraints would affect availability for the standard models, pushing them out compared with previous single-event iPhone cycles. NDTV’s reporting frames this as a departure from the pattern where all models typically appear in the same period.
While the sources agree on the general direction—Pro models on an earlier date and base models arriving later—details such as the exact length of the delay for the standard iPhones are presented as expected or reported rather than officially confirmed by Apple.
