Apple Seeds Third Betas of iOS 15.6 and iPadOS 15.6 to Developers

Apple today seeded the third betas of upcoming iOS 15.6 and iPadOS 15.6 updates to developers for testing purposes, with the new software coming two weeks after the release of the second beta.

iOS 15
Developers can download iOS 15.6 and iPadOS 15.6 through the Apple Developer Center or over the air after the proper profile has been installed on an iPhone or iPad.

We don't yet know what might be introduced in iOS 15.6 and iPadOS 15.6, as Apple has now implemented all of the features that were announced as coming in the iOS and iPadOS 15 updates, and work on iOS 15 is likely winding down with iOS 16 approaching.

There were no new features discovered in the first two betas of iOS 15.6 and iPadOS 15.6, suggesting these are updates focusing on bug fixes and other under-the-hood improvements.

iOS 15.6 and iPadOS 15.6 could be some of the last updates to iOS 15 and iPadOS 15 as Apple is now working on iOS 16, which is set to be released this fall.

Apple has also seeded new developer betas of tvOS 15.6 and watchOS 8.7.

Is this the version that will slow down my iPhone 12?
15.5 didn’t slow down my ip7 or 8. At this point (.6) it’s a safe bet to install it

I doubt it will be this week, 2 or 3 weeks after WWDC release.

Is 15.6 Beta 2 (19G5037d) the last update for my 6s?

Because I tried to update it to iOS 15.6 beta 3 (19G5046d) but it couldn't.
If its like the previous 2021 with iOS 14 you had the following:


* iOS 14.6 (18F72) - May 24, 2021
* iOS 14.7 (18G69) - July 19, 2021
* iOS 14.8 (18H17) - September 13, 2021

In other words Apple maintained iOS/IPadOS beta cycles up to the iOS 15 (19A346) - September 20, 2021 release.
From that point it will be repeating the iOS beta cycles until iOS 16 is release which drops support iPhones 6/7. Anything with iOS 15.x after that would be a security update.
