iOS 27 released today – full rollout guide for Apple users

Apple announced that iOS 27 is officially available today, marking the latest step in the company’s yearly software cadence. The update arrives with a host of under‑the‑hood improvements, security patches, and new UI refinements that will soon touch millions of devices worldwide.

Overview of the release

The launch of iOS 27 follows the typical Apple pattern of phased distribution, beginning with a wave that starts at 20:00 МСК. This timing ensures that users across the Russian time zone receive the update simultaneously, while other regions will see the rollout continue in subsequent waves over the next few days.

Device compatibility

Apple limits the new system to hardware that can support its advanced features. The update will be offered to iPhone models starting from iPhone 11, meaning that any device older than the eleventh generation will remain on the previous iOS version. Users of iPad also benefit, as the same binary is prepared for compatible tablets during the same rollout.

Preparing a backup

Before initiating the upgrade, Apple strongly recommends creating a fresh backup of all personal data. A completely free copy can be stored in iCloud by navigating to Settings → General → Transfer and Reset → Prepare for new iPhone. This process captures photos, messages, app data, and system settings, safeguarding against any unforeseen issues during installation.

Initiating the update

When the wave reaches your device, a notification will appear in Settings under Software Update. Tapping “Download and Install” begins the download, which typically consumes a few gigabytes of data; therefore, a stable Wi‑Fi connection is essential. The system will verify the package before proceeding, ensuring integrity and authenticity.

Post‑install actions

After the installation finishes, the device automatically restarts. Apple advises users to keep the iPhone on its charger and connected to Wi‑Fi for several hours. This idle period allows background processes to re‑index files, refresh caches, and complete any pending optimizations that improve overall performance.

Transitioning from beta to release

Users who have been testing the public beta must disable the beta channel to receive the final build. This is done via Settings → General → Software Update → Beta Updates, then selecting “Turn off”. The forthcoming Release Candidate carries the same version number as the public rollout, and any subsequent tweaks will be pushed to these devices as well.

Automatic AirPods update

One of the lesser‑known conveniences of the iOS 27 rollout is the seamless firmware refresh for AirPods. When an iPhone or iPad completes the system upgrade, any AirPods placed on their charging case and connected to power will download the latest firmware automatically, without user intervention.

Optimizing battery health after the upgrade

A fresh OS often recalibrates battery statistics. Apple suggests monitoring battery health in Settings → Battery → Battery Health & Charging for the first 24‑hour period. If the maximum capacity appears lower than expected, a full charge‑discharge cycle can help the system relearn accurate metrics.

Verifying the installation

To confirm that iOS 27 installed correctly, open Settings → General → About. The “Software Version” field should display 27 followed by the build identifier. Users can also check the “System Services” list for any pending background tasks that indicate the device is still processing post‑install routines.

Troubleshooting common issues

Some users report brief connectivity hiccups after the update. A simple network reset—found under Settings → General → Transfer and Reset → Reset Network Settings—often resolves these anomalies. If problems persist, restoring from the recent iCloud backup via Settings → General → Transfer and Reset → Erase All Content and Settings is a reliable fallback.

Security enhancements in iOS 27

The new release tightens encryption for iMessage and FaceTime, introduces stricter app sandboxing, and patches several zero‑day vulnerabilities disclosed earlier this year. These measures collectively raise the security baseline for all supported iPhone and iPad devices, reinforcing user privacy.

What’s new for developers

Apple provides developers with updated APIs that expose the latest hardware capabilities, such as refined sensor data handling and improved background task scheduling. The Release Candidate includes the same SDK version that will ship to the App Store, allowing developers to test compatibility before the public rollout concludes.

Looking ahead

While iOS 27 sets the stage for the next year’s innovations, Apple has already hinted at a major feature refresh for iPadOS later this calendar year. Users who keep their devices updated will be positioned to adopt those enhancements as soon as they become available, ensuring a seamless ecosystem experience across iPhone, iPad, and AirPods.

Final checklist

• Verify that your device is an iPhone 11 or newer.

• Create a fresh iCloud backup via Settings → General → Transfer and Reset → Prepare for new iPhone.

• Wait for the wave to start at 20:00 МСК and tap “Download and Install”.

• Keep the device charging and on Wi‑Fi for several hours after restart.

• Disable beta updates if you were on the public beta.

• Ensure AirPods are on the charger to receive the automatic firmware update.

Following these steps will help you transition smoothly to iOS 27, unlocking the latest features while maintaining data integrity and device stability.
