Post the California streaming event where Apple introduced the vanilla iPhone 13 range, the iPhone 13 Pro lineup, iPad mini 6, iPad 9th gen, and Watch Series 7, iOS 15 RC (iOS 15 Release Candidate) was released to beta testers. The RC version basically is in most cases the exact same build that the general public will get on September 20. We received the update on our 2020 iPhone SE with a whopping 4.87 GB size considering it is the final version of iOS 15.
Before you panic, please be informed that the RC build will replace the Beta 8 build on your iPhone, in case the size of the update bothers you. On that note, those of you enrolled in the iPadOS 15 Beta program may also update to the iPadOS15 RC build now. And users currently not part of the iOS 15 Beta program need not enroll in the beta and install this build as the general release is less than a week away.
iOS 15 RC for beta testers is in most cases the same official general public release build
To update your iPhone to the iOS 15 RC, simply go to Settings > General > Software Update and wait for the same to pop up in a couple of seconds. We haven’t updated our iPhone yet as we will do it later today and see how things go on. Speaking of which, we expect nothing more than performance improvements, polish, and bug squashes here and there ahead of general release.
