May 25 update: this post, first published on Saturday, May 23, was updated with more details of what’s expected to be in the new release, and when it’s expected.
It’s not even two weeks since the last iPhone update, iOS 26.5, was released on Monday, May 11, 2026. But the latest report suggests that there are already two more updates almost on the glide path. And the first of these, iOS 26.5.1, could be just days away. Here’s what’s in them and when they’ll land.
Apple iOS 26.5.1 Content
It’s not uncommon for Apple to follow a major-point release with a minor one, and the timing fits for iOS 26.5.1 to be on its way if its needed.
Mostly, but far from always, minor point releases are about bug fixes and security issues, and as iOS 26.6 brought one very big update — RCS messaging to make messages sent between Android and iPhone as secure as iMessages already were — the next update will almost certainly be to tweak features such as these.
It may still be light on security issues as more than 60 flaws were repaired in iOS 26.5, unless something didn’t quite take after all.
As for what fixes will be in the update, The Mac Observer has this take on the upcoming release.
“Reports from users still point to battery drain, overheating, app glitches, and occasional performance issues on some iPhone models,” it said. I’d add that although I heard initial commentary about battery drain from iOS 26.5, which is commonplace in the hours and days after installation thanks to the system re-indexing, this hasn’t seemed to be a major problem. It’s exacerbated if you’ve updated after a long time of avoiding releases, for instance if you’ve gone from iOS 26.1 to iOS 26.5, say.
Predicted Apple iOS 26.5.1 Release Date
“Apple’s software engineers are testing iOS 26.5.1, according to the MacRumors visitor logs, which have been a reliable indicator of upcoming iOS versions,” MacRumors reported.
That means the release is imminent, but when, exactly? Ordinarily, I’d say Monday, May 25 or Tuesday, May 26, but Monday is Memorial Day, so that’s unlikely.
Apple’s engineers will be working on it on Tuesday, so I believe Wednesday, May 27 or even Thursday, May 28 are the most likely dates.
The Mac Observer also has a thought about the release date. “That makes a quick iOS 26.5.1 release look very likely. Apple usually releases “.1” updates shortly after a major public build when post-update issues start surfacing across supported devices. In recent years, these smaller patches have focused on fixing real-world problems instead of adding major new features,” it commented.
Apple iOS 26.6 First Developer Beta And WWDC
The MacRumors logs also revealed that Apple is simultaneously testing iOS 26.6, which will likely be one of the last releases for the iOS 26 cycle.
Although testing has started, if Apple follows the same schedule as last year, the first beta may not be sent to developers until after WWDC, which runs from June 8 to 12.
