At the WWDC 2026 keynote, Apple detailed iOS 27 changes like a new version of Siri with a dedicated Siri app and Apple Intelligence features across multiple apps, but there are dozens of smaller but still important changes that Apple didn’t have time to go through.
Apple shared an image summarizing some of the bug fixes and optimizations it made in iOS 27, iPadOS 27, and macOS 27, and there are some interesting changes.
Dual Phone Numbers
Apple says you’ll be able to switch between two iPhone devices with the same phone number, which presumably means you can set up two iPhones with one number and then swap between them as needed. It could work similar to how an iPhone and Apple Watch can share the same phone number. It should be a useful change for anyone who wants to get a foldable iPhone and a standard iPhone 18 Pro this year.
Sharing numbers between two iPhones may require carrier support, so it’s not clear if it’s implemented in the beta.
Two FaceTime Cameras
Dual camera in FaceTime is a listed feature, and that likely means you’ll be able to use the front and back cameras at the same time during FaceTime calls.
Faster AirPlay and AirDrop
AirPlaying content to the HomePod and Apple TV is faster than before thanks to multiple system improvements. AirDrop transfers from the iPhone to other devices are also faster, and it’s quicker for an iPhone to find nearby AirDrop recipients.
Messages Drawing App
There’s a drawing app in Messages where you can handwrite a message or draw a picture. It uses the same drawing tools that are available in the Notes app or when annotating images.
Extra Large Widgets
There’s a new extra large widget size you can select on the iPhone’s Home Screen. The extra large size takes up an entire app page and displays more information from an app.
Shared Album Expirations
You can now set a shared photo album to expire after a set time, so it doesn’t exist indefinitely.
Independent Alarm Volume
Alarm volume can be controlled separately from system volume, as can alerts and system sounds. In Settings > Sounds & Haptics, there are toggles to match Alarms, Timers, Alerts, and System Sounds to Ringtone Volume or to decouple them. Toggling off the match option lets you select a preferred volume level for alarms and system sounds.
Markdown in Notes
You can now copy and paste Markdown in the Notes app.
Save a Video Frame
There’s a new option to save a video frame as a photo in the Photos app.
Weather
The Weather app has a “Highlights” view with at-a-glance information, plus it includes updated hourly and 10-day views for precipitation and wind speed.
Other iOS 27 Optimizations and Changes
Faster message loading in Mail
Enhanced Safari power efficiency
Improved battery insights
Smoother scrolling in App Library
Smoother unlocking on iPhone
New AutoMix transitions in Apple Music
Faster HomeKit accessory pairing
Faster start page loading in Safari
More accurate Visited Places in Maps
Improved Messages syncing across devices
More power efficient personal hotspot on devices with N1 chip
Failed messages will automatically try resending
Improved Bluetooth power management
Support for time zone changes in Sleep
Improved unread badge accuracy in Mail
These are just some of the improvements and changes that Apple has introduced in iOS 27. We’ll be sharing more new features in iOS 27 as they’re discovered by the community. The iOS 27 beta is available for developers right now, with Apple planning to introduce a public beta in July. iOS 27 will launch this fall.
