The iOS 27 public beta is now available, and one of the big changes is that it makes your iPhone a lot faster. In fact, Apple has outlined more than 30 ways in which your iPhone will be faster after you update.

How iOS 27 makes your iPhone faster

When Apple announced iOS 27 last month, the company emphasized that it combed through its software to make it faster and more reliable. “Improvements across platforms push key system capabilities forward so everyday tasks feel faster, smoother, and more enjoyable,” Apple said.

Performance updates have been a recurring theme in recent iOS versions. iOS 15 introduced app privacy improvements and a focus on speed, while iOS 16 brought the revamped Lock Screen and widget enhancements but also faced early stability issues. iOS 17 continued with interactive widgets and significant under-the-hood refinements, and iOS 26 delivered enhanced iMessage features and Photo processing optimizations. Now, iOS 27 represents one of the most comprehensive speed-focused updates in years, with Apple systematically targeting each major functional area of the iPhone experience.

The list of improvements covers the entire system, from the moment you wake your iPhone to the way you share files with others. Here are the more than 30 ways iOS 27 accelerates your everyday tasks:

Photos and Camera

• Faster loading of new captures in Photos (up to 70% faster)
• Faster to open full-screen view from Photos widget
• Faster rendering of Collections tab in Photos
• Faster to start uploading to iCloud Photos
• Faster Camera launch in Low Power Mode
• Faster to add recent camera captures in Messages
• Faster Text Recognition in photos and documents

The Photos app has been a particular focus. The 70% improvement in capture loading means that after taking a burst of images, they appear almost instantly in the library. This is paired with faster iCloud Photo uploads, which will benefit users who rely on cloud storage. For Low Power Mode, camera launch speed was a common complaint, and iOS 27 addresses that directly, ensuring that even when battery is low, the moment is not missed.

Browser and Web

• Faster start page content loading in Safari
• Faster web application performance in Safari
• Faster handling of JavaScript in Safari

Safari has become more competitive with these enhancements. Faster JavaScript execution means websites and progressive web apps (PWAs) behave more like native applications. Start page content loading reduces the time before you see your frequently visited sites—something web developers have long requested to match the speed of native apps.

Communication and Connectivity

• Faster message loading in Mail
• Faster HomeKit accessory pairing
• Faster smart home accessory updates
• Faster AirPlay connections to Apple TV and HomePod
• Faster and more reliable NFC reading
• Faster AirDrop transfers (up to 80% faster)
• Faster AirDrop recipient discovery

AirDrop receives the most dramatic speed bump at up to 80% faster transfers. This means sharing a 1GB video file might now take seconds instead of minutes. Additionally, HomeKit pairing—historically a slow process—becomes significantly quicker, which should encourage more users to add smart home accessories. NFC reading speed improvements also bolster Apple Pay and other contactless interactions.

Media and Entertainment

• Faster Now Playing view loading in Music
• Faster Apple Music playback start
• Faster board previews in Freeform
• Faster workout start in the Workout app

Music-lovers will appreciate the immediate playback start, especially when resuming a song from a paused state. Freeform—the collaborative whiteboard app—sees faster board previews, making it smoother for team brainstorming. Workout app also gains a speed boost, reducing the lag between tapping “Start” and seeing the countdown.

System-Level Optimizations

• Faster Lock Screen switching
• Faster app launches (up to 30% faster)
• Faster network file browsing
• Faster PDF saving
• Faster loading of emoji and sticker keyboards
• Faster shortcuts and actions indexing in Spotlight
• Faster multilingual text processing for handwriting
• Faster entry and exit from Assistive Access and Guided Access modes
• Faster Voice Control response
• Faster Rapid Return to Service
• Faster access to shared content on iCloud.com

The app launch speed improvement of up to 30% was measured by Apple using the iPhone 11 Pro Max comparing iOS 26.4.2 and iOS 27. This is a significant boost for older devices, which often suffer from slower app opening times as software advances. The faster Lock Screen switching also makes using multiple widgets or accessing the Camera from the Lock Screen feel instantaneous. PDF saving, emoji keyboard loading, and Spotlight indexing improvements contribute to a snappier overall feel that users will notice throughout the day.

9to5Mac’s Take

iOS 27 is compatible with iPhone models dating back to the iPhone 11. In fact, Apple even says that some of its performance metrics are based on testing it conducted with the iPhone 11 lineup. For example, Apple says that apps launch up to 30% faster with iOS 27. This statistic is based on testing Apple performed on the iPhone 11 Pro Max, comparing app launch speeds between one model running iOS 26.4.2 and another running iOS 27.

All of this is very impressive — especially for people using “older” iPhone models. Apple has fixed enough bugs and made such a jump in performance that I think most iPhone users will notice a big improvement when they install iOS 27 later this year. It’s particularly impressive when you consider Apple made all these improvements to performance while simultaneously implementing a ground-up revamp of Siri.

iOS 27 is currently available to developers and public beta users. It will be released to everyone later this fall.

The scale of these improvements also highlights a broader company strategy: Apple is increasingly aware that software optimization is just as important as new hardware. With the iPhone 16 series already offering capable processors, the cumulative effect of dozens of speed enhancements can make even year-old devices feel rejuvenated. This is especially crucial as users hold onto iPhones longer—the average replacement cycle now exceeds four years. By ensuring that older models like the iPhone 11 can achieve app launches 30% faster, Apple effectively extends the usable life of its devices, aligning with both consumer expectations and environmental sustainability goals.

Moreover, these optimizations set the stage for future features. A faster base system allows new functionalities like the Siri overhaul, advanced multitasking, or augmented reality apps to run without performance penalties. The groundwork laid in iOS 27 will likely benefit subsequent updates, enabling Apple to push the envelope without leaving older hardware behind.
