One of the main advantages of Apple smartphones is their long software support. While many Android smartphones stop receiving major updates just 2–4 years after release, iPhones usually remain relevant for much longer.

That’s why many users readily buy even models that are a few years old. They know that the smartphone will continue to receive new features for a long time and will remain safe for everyday use.

Apple does not set a single official term. The company does not promise a specific number of years of support for each model, but recent practice shows that most iPhones receive new versions of iOS for about 5–7 years after release.

After that, many devices still receive security updates for a while, even if a new version of the operating system is no longer available for them.

This approach allows users to enjoy their smartphones for much longer without the risk of missing important fixes.

The main reason is that Apple develops both the software and the processors for its smartphones in-house. This allows the company to optimize iOS for specific models and support them for many years.

Another advantage is the simultaneous release of updates. When a new version of iOS is released, it can be installed on almost all compatible iPhones within the first few days. Owners do not have to wait for months while the manufacturer adapts the system for a specific model.

When Apple stops releasing new versions of iOS for a certain smartphone, it does not mean that it immediately stops working.

Most features remain available, you can make calls, use the browser, messaging apps, and most applications. However, over time, some apps may stop supporting older versions of iOS, and new features of the operating system will become unavailable.

That’s why very old models gradually lose their relevance.

In many cases — yes. If the smartphone is still receiving iOS updates or at least security updates, it can remain a great choice for the next few years.

That’s why previous generation models often have an optimal price-to-performance ratio. They run quickly, support modern applications, and are significantly cheaper than the latest flagships.

Before purchasing, you should just make sure that the model is officially supported by Apple and has enough memory for your needs.

If you plan to use the smartphone for 4–6 years, it’s better to choose one of the current models or a previous generation device that has recently gone on sale. This will ensure the maximum support period and allow you to receive new versions of iOS for a long time.

It’s equally important to pay attention to memory capacity, processor performance, camera capabilities, battery capacity, and the availability of an official warranty.
