Every day that passes means one day less waiting to enjoy the presentation of the iPhone 15, Apple Watch Series 9, Apple Watch Ultra 2023, etc. Apple’s new smartphone is one of the most anticipated in recent years, and it is partly due to all that it is expected to carry. We are talking about a titanium body, more battery, thin frames, and the A17 Bionic chip, among other novelties.
The day that the event will take place is something that Apple usually keeps secret and that is related to all this. We know it usually takes place in September, generally during the second or third week and on a Tuesday or Wednesday, but that opens up many possibilities. However, that date may have leaked, and it seems pretty plausible.

If this is true, and if the usual pattern were followed, reservations would be on September 15 , and the first units would be delivered on September 22. It sounds reasonable, although it is also true that this is precisely one of the things that Apple can change before to announce it without having repercussions, so it is not set in stone either.
