Like any smartphone company, Apple wants users to change their smartphones as often as possible. So much so that, in recent days, the company has created a page dedicated to those who want to upgrade, but have questions.
The weird part is that This page Intended for those who have an iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone 12, iPhone 12 mini, iPhone 12 Pro, or iPhone 12 Pro Max, these are the models that Apple believes may require an upgrade.
In other words, if you have an iPhone 13, iPhone 14, or even an older model like an iPhone XS or iPhone The truth is that, given the way the page was created, it would be interesting to have other, older models.
See the differences between older models and iPhone 15
If you have one of these models, the page helps highlight the key differences that justify upgrading to the latest models. The iPhone 15 is clearly a better smartphone than older models, and it remains to be seen if this actually justifies the upgrade in your case.
This page is interesting for those who have an older model and have no idea what has changed in these newer models. Especially since for many regular users, not much has changed to justify the change.
The truth is that from iPhone 11 to iPhone 15 there are big changes in cameras, processor or storage space. This generation also finally uses a USB-C port, we have 5G, a better battery, and an OLED display.
