On December 13, Apple released iOS 16.2, its most significant iOS 16 update yet. On December 14, the first developer beta of iOS 16.3 was released. There’s no rest for the weary, as they say.

We’re not yet sure what to expect from iOS 16.3. With the last update, we got the last of the significant features promised for iOS 16, but Apple often has some surprises in store. Apple Music Sing is a perfect example of a feature nobody knew about until days before its release–it came late in the iOS 16.2 testing cycle and was not previously announced or rumored.

The beta typically is released for developers first, with a public beta typically following within a day. We don’t expect the final release until sometime in January or February.

Update 01/10/23: The second beta of iOS 16.3 has been released. There was only one significant new feature in the first beta, but we’ll update this article as additional features are discovered.

iOS 16.3: Release date

How to install the iOS 16.3 Developer beta

Each stage of iOS 16.3’s development cycle will be rolled out to developers first, and then to public beta testers afterwards (typically within a day or so). If you’re a developer and need to test your apps against the most up-to-date version of the OS possible, this is the version to run.

First, check that your device is compatible. Have a quick read of which iPhones and iPads can get iOS 16?

iOS 16.3: Risks and precautions

Note first of all that betas are test versions of upcoming software. They are by definition unfinished, and while they should include most or all of the features in the finished product, there will be cosmetic differences and, inevitably, some bugs and other issues that will need to be fixed during the development process.

In other words, don’t expect a perfect user experience. In particular, some existing apps (including ones that you may rely on) might not work perfectly with the new version. In extreme cases, you may even find that your device is bricked by the beta, and cannot be used until the next beta comes along. It’s not uncommon for early beta software to exhibit problems like excessive battery drain as well.

We can’t stress enough how important it is to back up your iPhone before you install a beta on your device, or better still, use a secondary device rather than your main iPhone or iPad.
