Every time Apple releases a new iOS update, people swear their iPhones suddenly feel slow. These rumors have followed Apple for years and while the company has always denied it, the suspicions have never really gone away. With its latest iOS 27 update, I believe Apple has finally put these rumors to rest.
I installed the beta on my iPhone Air, but the big issue is what happens to older models. Reports from people using iOS 27 even on older iPhones say their phones feel faster, not slower.
That’s the opposite of what the outdated crowd has wanted all these years, and it happens in a developer beta, which is usually the biggest, least optimized version you can find.
So what has changed this time?
According to Apple, the speed benefits come from redesigning how the system handles things like CPU scheduling, memory, and background tasks. In plain words, your iPhone is now smarter about where it spends its energy, so older chips don’t focus on doing work they don’t need.
Apple is churning out crazy numbers. It says app launch is up to 30% faster, AirDrop is 80% faster, Photos load almost 70% faster, and a few other improvements across the board. I tend to take these statistics with a grain of salt, as there is no way to test them mathematically. But with the results I’m seeing on my iPhone Air, I will say that something feels genuinely different.
I’m particularly impressed with the new AirDrop. You can really feel the improvement in transfer speeds. Small files transfer in a jiffy, and even larger video files take about half as long to transfer as they did in iOS 26.
But the best part is that Apple didn’t lock these enhancements behind the new iPhones. Every device that can run iOS 26 can run iOS 27, going back to the iPhone 11. Yes, older devices may miss out on new AI features, but they all get speed and stability improvements that will extend the life of these devices.
Does this mean the rumors were always wrong?
I wouldn’t say so. Older iPhones slow down over time, but it’s not a bad idea. New features require more powerful chips, applications become more complex, and battery life naturally decreases, which can reduce performance. Apple itself has admitted that it slows down the performance of older iPhones to get more battery life. The company even had to pay more than $600 million to settle the lawsuits.
The iOS 27 update changed this narrative. Instead of adding fancy new features that require the latest hardware to function properly, Apple has spent this year making the experience better for everyone, including people stuck with older phones. For this reason, iOS 27 is the most important update that Apple has released in years.
It ensures that my iPhone will last me a long time, and that I’m not counting down to my next upgrade. I’ve always been against a maintenance update every few years if not every year. If Apple continues to deliver these updates, these planned rumors will end quietly.
