June 4 update. This post, first published on Monday, June 1, has been updated to reflect exactly which iPhones for which this update is relevant, and more details of the release, and its timing, coming just before iOS 27 is revealed.
The new iPhone update is here, three weeks since the major-point iOS 26.5 release which landed on Monday, May 11.

As such, it’s no surprise that this is not a Background Security Improvements update as those are all about security fixes. Apple’s support website specifies that “this update has no published CVE entries,” that is, there are no security fixes here.
How To Download And Install iOS 26.5.1

It’s a sizeable update, 17.44GB on my iPhone 17 Pro Max, but the size of the update will depend on how long ago you previously updated the phone.
