Most years, major iOS updates offer the same basic feature set on new iPhones and old ones. But with iOS 27 things are different, and anyone with an iPhone 15 or older will miss out on a lot of new features. Here’s why iOS 27 makes a strong case for considering an iPhone upgrade.
iOS 27 is entirely built around Siri AI and other Apple Intelligence features that are better than ever

iOS 27 technically supports all the same iPhone models as iOS 26 did. That means anyone with a model as old as 2019’s iPhone 11 can get the update.
But if your device doesn’t support Apple Intelligence, there’s not much new that’s worth getting excited about.
That’s because iOS 27 brings arguably two firsts for Apple. It’s the first iOS update where:
- Most new features involve AI
- Those AI features are actually quite good and useful
I’m not an Apple Intelligence hater. I’ll admit there were plenty of solid AI features before iOS 27. But there wasn’t much that was likely to motivate a new iPhone purchase.
With iOS 27 though, Siri AI alone is a massive upgrade.
It not only makes Siri good at the everyday tasks you might expect, but it’s also a privacy-friendly, powerful AI assistant that has already started changing the way I use my iPhone.
Beyond Siri, iOS 27 has other useful AI features like one-tap suggestions in Messages, natural language input in Calendar and Reminders, much-improved search in Mail, powerful editing tools in Photos, and a lot more.

For Europeans, it’s exactly the opposite. Siri AI won’t be available, and iOS 27 will finally fix bugs and performance issues. That gives users even more reason to hold on to their older iPhones, because they’ll get a better experience without spending a single cent. I think that’s also one of the reasons Apple was so frustrated that it publicly blamed the European Union.
If you add these improvements to all of the existing AI features iOS supports, like notification summaries, Apple Wallet’s AI order tracking, improved search in many system apps, and Live Translation across Messages, Phone, FaceTime, and AirPods—there’s a lot to be gained from having an AI-compatible iPhone.
Plenty of people are skeptical of AI, and perfectly content avoiding AI features as long as possible.
But if you can ignore the ‘AI’ label, Apple has built new features into iOS 27 that I suspect the average user will find worthwhile. They make the iPhone experience better, and offer a great reason to consider an upgrade.
