If your iPhone has felt slower over the past year, iOS 27 could bring some welcome improvements. During WWDC 2026, Apple revealed that its next major software update includes a range of performance optimizations designed to make supported iPhones feel faster, smoother, and more responsive, especially older models.
That is notable because iOS 27 supports devices as old as the iPhone 11, which first launched in 2019. While many headlines around the update have focused on Apple Intelligence and the new AI-powered Siri experience, Apple is also making significant under-the-hood changes that could improve the day-to-day experience for millions of iPhone users who are not planning to upgrade anytime soon.
According to Apple, iOS 27 delivers several measurable performance gains across the system. Apps can launch up to 30% faster, Photos can display newly captured images up to 70% faster, and AirDrop transfers can be up to 80% faster in certain situations. Apple also says users should notice improvements when saving PDFs, launching the camera in Low Power Mode, starting workouts, and loading content throughout the operating system.
A major reason for these improvements is Apple’s work on the iPhone’s CPU scheduler. This system manages how processor resources are distributed between apps and background tasks. With iOS 27, Apple has brought many of its latest scheduling optimizations to older supported devices, helping them prioritize active tasks more efficiently and reducing delays during everyday use.
The changes are already drawing attention from early beta testers. Across online forums and social media, many users report that iOS 27 feels smoother than iOS 26. Some say animations appear more fluid, apps launch quicker, and overall responsiveness has improved. Several users have even described the update as the version of iOS 26 they originally hoped to get.
That does not mean the beta is perfect. As with any early software release, some testers have reported battery drain, graphical glitches, refresh rate issues, and other bugs. Apple is expected to address many of these problems before the public release later this year, which is why most users should avoid installing developer betas on their primary devices.
Still, the positive feedback is encouraging because performance-focused software updates are relatively uncommon. Instead of concentrating solely on new features for its latest hardware, Apple appears to be investing in improving the experience on devices that are several years old.
For iPhone 11 owners in particular, this could be one of the most important aspects of iOS 27. The device is now entering its seventh year on the market, yet Apple continues to support it with major software updates. If the company’s performance claims hold up in real-world use, users may be able to keep their devices for another year or two without feeling pressured to upgrade.
The strategy also reflects a broader shift in how people use smartphones. Upgrade cycles continue to lengthen as device prices rise and hardware improvements become more incremental. Many users are choosing to keep their phones longer or buy refurbished models instead of purchasing the latest flagship. By improving performance on older devices, Apple can extend the life of existing iPhones while strengthening one of its biggest competitive advantages: long-term software support.
There is one important limitation. While older devices will benefit from these performance improvements, they will not get access to Apple Intelligence features. The new Siri experience and other AI-powered tools require an iPhone 15 Pro or newer. However, for users who simply want a faster and more reliable iPhone, iOS 27 could still be one of the most meaningful updates in years.
So, will iOS 27 make your iPhone faster? Apple says yes. Early benchmarks, technical improvements, and initial user reports all point in that direction. We will not know how much of a difference the update makes until the final release arrives this fall, but for owners of older iPhones, the signs are promising.
