If you're shopping for an iPhone or just trying to understand which model came out when, the naming system can feel confusing. Apple has released dozens of models over nearly two decades, and they don't always follow an obvious pattern. This guide walks you through the major iPhone generations and helps you understand what's changed over time.
Knowing when an iPhone model was released tells you several practical things: how long Apple will support it with software updates, what features it likely has, and whether parts and repairs are still readily available. Older models often can't run the latest software, which affects apps, security, and performance. Newer models typically cost more but come with longer support windows and modern capabilities.

Annual cycles: Apple typically releases new iPhones every September or October. Each "generation" (marked by number—11, 12, 13, etc.) usually lasts about a year before the next one arrives.
"Pro" vs. standard models: Since the iPhone 11 Pro (2019), Apple has offered a tiered lineup. Pro models cost more and include upgrades like better cameras, premium materials, and faster processors. Standard models are more affordable and meet most people's needs.
Size options: Since the iPhone 6 Plus (2014), Apple has offered larger screen sizes. Since the iPhone 12 Mini (2020), some generations also include a smaller "Mini" option, though these have become less common.
Support and updates: Apple generally supports iPhones with software updates for around 5–6 years after release. Older models eventually can't run the newest iOS version, which limits app compatibility and security patches.
Your decision depends on several factors only you can weigh:
Understanding the timeline helps you make an informed choice based on your own priorities and circumstances.
