Yay!

 

[TheYayAreaLiving 🎗️]

Thank you @Banglazed. You rock!

I wonder if this is the last version of iOS 15 before IOS 16 beta 1 is out in June.

Not coming up for me as a download

Not coming up for me as a download

Rebooted my iPhone/iPad and it’s there!??

 

[Leap_Ahead]

No ota on Developer profile?

 

[Jumpie]

Rebooted my iPhone/iPad and it’s there!??

Do I need to delete the beta profile? I did reboot and nothing.

 

[BugeyeSTI]

I'll update when it's available on iTunes later today.. Seems to work better for me.

 

[Cpives]

I’m not seeing anything on OTA

 

[coffeeplease]

My iPad has been draining more in standby. Hope this fixes it.

Remove beta profile

 

[Jumpie]

Remove beta profile

That likely means no more betas until 16.

 

[mppn]

That likely means no more betas until 16.

rather the complete oposite....

 

[Samdh90]

Apple officially posted the changelog. Not too in depth but does mention the battery drain being fixed. YAY! lol

 

[adrianlondon]

I'll keep my beta profile installed, skip this release (iOS 15.4 is running really well for me) and wait for the next beta.

Ditto for today's MacOS release.

I had to delete my profile

Hi! This is the first iOS-update being able to download with mobile data with LTE/4G in Sweden. I know there was talk about this during iOS 15.4 beta (not be limited to Wi-Fi-network when downloading iOS-updates..) but have not been able to find any confirmation that this is released. Either way it might be limited to different countries but I have tested on two different carries with two different Apple iPhone devices (Carrier Tele2 and Telia with iPhone 13 and iPhone 12 mini) and both show this option. The option says something like: "Downloading iOS-updates using mobile data might bring extra charges" press yes to continue or cancel etc..

I think it is a bit early… don’t you think? I mean, yes, technically we could only get some bug-fixing and stability updates in the form of iOS 15.4.2, or 15.4.3… But I would find it strange to not have any major update in more than 2 months. We’ll see.

 

[BugeyeSTI]

Available on iTunes, updating now!

Anyone getting the watch OTA? My series 7 isn't seeing it and I don't have a profile instealled.

Same here, I have Hallon.

Try reboot as someone suggested

That’s the first time I see this popup on locked screen. Is it new or I am just today-years-old?

It says “Verifying the update”

 

[Reeneman]

Im sure we will see a 15.5 but it won’t be an exciting release.

 

[TheYayAreaLiving 🎗️]

Well, this is interesting.
