Have you been wondering which version of iOS your iPhone can actually run? This guide provides a straightforward path to discovering if your trusty device can embrace the latest bells and whistles of Apple’s iOS or if it’s due for a hardware facelift.

Annual iOS Evolution

Annually, Apple rolls out a comprehensive update to iOS, packing in new features, interface tweaks, and crucial security patches. iOS 18 graced our devices in September 2024, with incremental updates, like iOS 18.3 in January 2025, ensuring continuous enhancements. According to Macworld, iOS 18 loves those who hold onto iPhones from 2018 and newer, encompassing devices like the iPhone XR, XS, and the 2nd Gen SE.

A Peek into the Future with iOS 19

While iOS 18 brings a lot to the table, Apple enthusiasts eagerly await iOS 19, set to hit devices later in 2025, likely extending support to all phones since the iPhone XR. But take note, some advanced features may require a more recent model than iOS 18 demands.

When Should You Upgrade?

It’s well known that Apple excels in maintaining support for older models, granting them longer lifespans than many other brands. However, once security updates cease, as happened recently for iPhones running iOS 16 and older, it’s prudent to consider upgrading to guarantee device security and access to newfangled features.

To quell any remaining doubts, let’s break down which iOS iterations each iPhone generation can handle. Note that with the turn of the page to September 2024, Apple has bid farewell to devices running iOS 16 and older, thus marking the end of support for popular models like the iPhone 8, X, and beyond. Below is a quick reference for which iOS your iPhone should be compatible with:
