Reasons to buy the iPhone 16
The biggest reason to buy the iPhone 16 is support for Apple Intelligence (AI). This feature is supported on iPhone 15 Pro and iPhone 15 Pro Max models and later, and is limited to certain models.
While the iPhone 14 and iPhone 13 series are still perfectly usable, these models don't support Apple Intelligence (AI), which makes the iPhone 16 a particularly attractive purchase.
In addition, the iPhone 16 Pro and iPhone 16 Pro Max are noteworthy models, as they have also seen improvements in basic specifications, such as larger screens and the addition of camera controls. However, it is important to note that Apple Intelligence (AI) is expected to be available in Japanese from next year onwards.

The iPhone 16 has certain upgrades in terms of functionality compared to the iPhone 15, but the iPhone 15 is relatively cheaper and has sufficient functions. Depending on your needs, please consider whether you need to upgrade to the iPhone 16.
