Apple has released iOS 26.3 and iPadOS 26.3, introducing a long-requested tool that makes it easier for users to switch from an iPhone to an Android device.

The update, which began rolling out Wednesday, also includes security patches addressing dozens of vulnerabilities.

However, users quickly pointed to a different issue: The size of the update itself. Many users reported downloads measuring in the double digits of gigabytes.

The release arrives nearly two months after iOS 26.2 and continues Apple’s incremental updates to the operating system first introduced in September.

Why It Matters

Large software downloads can present challenges for users with limited storage or slower internet connections.

Significant file sizes may delay installations and require users to temporarily free up space on their devices.

Security updates included in iOS 26.3 carry urgency. Apple says the update fixes dozens of vulnerabilities, including one that “may have been exploited in an 'extremely sophisticated attack’ against targeted individuals on versions of iOS before iOS 26."

What To Know

The update was released on Wednesday.

The standout feature is a new tool designed to simplify moving data from an iPhone to an Android device.

According to MacRumors, the update introduces “a new transfer tool that lets an iPhone user place their device next to an Android device to initiate a transfer process.”

With the devices connected, users can transfer photos, messages, notes, apps, passwords and phone numbers without installing third-party apps.

The publication noted that health data, Bluetooth pairings and certain protected items are not transferred.

Beyond the transfer tool, iOS 26.3 includes a setting to limit carrier location tracking for supported networks and addresses numerous security flaws.

Apple recommends all its users move to the new update as soon as possible.

What People Are Saying

Commenters on Reddit's r/iOS forum were shocked by the size of the update.

"Wow 11GB," one commenter noted. "I hope that's a lot of bug fixes."

"12.14GB on 17 Pro," another user added. "Makes no sense for a bug fix update to be that huge."

Several users noted how different the update was for various people.

"From all the reports, everyone else is the same," one observed. "This particular update just has a gigantic variance in size for whatever reason."

"The update is the whole OS in a signed package for security purposes," one individual posted. "This is not a small patch."

What’s Next

Apple is expected to begin beta testing iOS 26.4 within weeks, with additional features anticipated in that release.

In the meantime, Apple is urging users to install iOS 26.3 promptly to ensure they are protected against the disclosed vulnerabilities.
