Which iPhones are compatible with iOS 18 and Apple Intelligence?
With the arrival of the new iPhone 16, it's now important to know which models will be compatible with iOS 18.
The big news with this operating system is the introduction of a new feature called Apple Intelligence. The goal is to improve the user experience by implementing Artificial Intelligence (AI) features for text and image content creation, as well as facilitating interaction with virtual assistants like Siri.
These iPhones support iOS 18 and Apple Intelligence
According to Apple, iOS 18 will be compatible with the following models: SE, XR, XS, XS Max, and generations 11, 12, 13, 14, and 15.

However, to operate Apple Intelligence, models need to have an A17 Pro Neural Engine chip or higher. This support is only available in two previous versions – the iPhone 15 Pro and iPhone 15 Pro Max – and in the new iPhone 16, iPhone 16 Plus, iPhone 16 Pro, and iPhone 16 Pro Max.

Note that, for now, Apple Intelligence will only be functional on devices configured in English. In 2025, it will be extended to other languages, such as Spanish and French, but Portuguese will not be included. Check the requirements to activate this feature here.
Which older iPhone models are worth buying?
Any iPhone from the XS model onwards will be a good bet, as all of them can install the new iOS 18 operating system. However, if you want to take advantage of all AI features, the iPhone 15 Pro and iPhone 15 Pro Max are the best options.
These models were the first to use the titanium design, which makes them extremely light, resistant, and comfortable for intensive daily use. Furthermore, they are faster and more efficient and, thanks to the A17 Pro chip, they enable the use of Apple Intelligence.
For photography and video lovers, the 48 MP cameras are also a big attraction of the iPhone 15 Pro and iPhone 15 Pro Max, as they allow capturing professional-quality images.
Another freedom for those who acquire these models is the implementation of USB-C, making them compatible with most accessories already available on the market.
The battery also lasts longer. In the case of the iPhone 15 Pro Max, the battery life is approximately 29 hours, ideal for energy-intensive functions such as video recording or gaming.

Which iPhone models will no longer be sold by Apple?
The iPhone 13, the iPhone 15 Pro, and the iPhone 15 Pro Max are the models that have already been discontinued by Apple. But there's no need to worry, as these phones will continue to receive updates for many years.
The added value of the iPhone 15 Pro and iPhone 15 Pro Max is that, from the new iOS 18 update, Artificial Intelligence features will become available, just like on the new iPhone 16.
Apple has already removed the discontinued models from its official website. Therefore, the best option to acquire them is to go to a refurbished store, such as iSell & Repair.
In our store, all refurbished iPhones come with a 3-year warranty and undergo rigorous quality tests before being put up for sale. This is the best way to get a high-quality phone at a significantly reduced price!
