iOS 27 Beta 2 ― Bug Fixes, Changes, and Improvements

[uczcret]

IPSW is out

And promptly bricked my 17PM. Wish I'd checked this thread first. 🤦‍♂️

 

[ghostface147]

So far looks like I am sticking with Beta 1.

The laughable performance when switching homescreens and the icon redraw are related to theming.

If I turn boring normie mode back on, it runs fine.

 

[CrisiomiroX]

Been running DB2 for the last hour and so far - fingers crossed - no issues.

The only minor gripe is that Write with Siri isn’t showing up for me (despite having new Siri). But everything else I’ve tried has worked - so far.

 

[The-Barron]

Just for info, not as scaremongering.

Had a white screen of death on my 16PM following the restart after update and entering passcode. Taken 30mins to revive.

Did this new auto restore procedure I’ve never seen before.

“Attempting data recovery”

 

[iCrow]

Really impressed on iPhone 12 Pro Max

 

[Séamus Boyle]

Everything smooth so far for me on beta2 on 17 pro. Weird there’s no watch update out today though.

 

[jdavid_rp]

Going quite fine on iPhone 15. Finished indexing on beta 1 and didn't reappear.

Worked like a charm for me. I updated my Mac to b2 and then the iPhone via IPSW

17 Pro updated to Beta 2 OTA no issues. Indexing finally disappeared, was still in progress before update.

Siri can now add things to lists without adding the word "List" to the end and asking to create a new one, or just creating a duplicate of an existing list.

And yes, cropping screenshots now save correctly.

Did you try to reboot again to see if it was reproducible? Id be a little reluctant. lol.

 

[adrianlondon]

I can ask Siri to FaceTime one of my contacts, and it does so. Same as B1.

Prior to iOS 27, I had to unlock my phone first.

I'm not yet sure whether I like this change or not, but it is more convenient.

 

[adrianlondon]

Also - I just rebooted my phone and not only did it boot up fine, but I got the standard "x automations are scheduled on your phone" warning.

CoreAI / Neural Engine → Loading of large models has been accelerated, CPU/GPU scheduling has been made more efficient.

Memory Management → Accurate memory allocation to application processes reduced CPU overhead.

Background Processes → Neural Engine access has been restricted, preventing unnecessary CPU overhead.

GPU–CPU Coordination → CPU blocking issues during GPU inference have been resolved.

Metal 4.1 API → Graphics processing validation and debugging improved, CPU-GPU collaboration smoother.

SwiftUI Framework → Unnecessary re-evaluations were removed with the @State macro, reducing CPU load.

SwiftData → Deadlock and synchronization issues have been resolved, CPU threads run more smoothly.

Dictation (Speech-to-Text) → Faster and more accurate with the new on-device model, CPU load optimized.

On the developer page, these titles stand out seriously when it comes to performance. I'm using an Iphone 12 and it has a serious performance improvement. Friends experiencing issues with their phones should upgrade to iOS 27 via their computers.

Another feature I like about iOS 27 is that when we take a backup and restore, the layout on the home screen remains the same. The thing I had previously noticed was excessive CPU usage in beta 1; I assumed this was a systemic issue, and now CPU usage is quite stable.

“Attempting data recovery”

This is why you shouldn’t (force) restart so soon after an update.

 

[JMRipollG]

None of my automations are running. I also don't get the usual warning about how many I have enabled upon boot. I've tried restarting and also disabling all automations and re-enabling.

Same. Other shortcuts work fine but automations are busted.

Just (soft) restarted my iPhone 17 (about 90 minutes after updating to Beta 2), no issues.

 

[Reeneman]

The Messages settings show iMessage is turned off but can still send iMessages.

It’s a trap

 

[Sal09]

So whose Battery Health dropped after performing an update 😜

 

[Jakimo]

It’s in the same place the previous indexing message was. On the main settings page.

Strange.. my iP Air wasn't finished with indexing on beta 1. Installing OS updates has always introduced updating the index

The very moment my beta 2 install completed, there has never been an indication of progress

(shrug) -- the beta 2 update is fly, everything is quick and quite nice. This beta cycle is likely the most reliable I've ever seen for the iPhone! Good work on Apple's part

for me, it's just watching and hoping for Siri improvements at this point! I get a lot of 'Uh oh, there's a problem. Please try again.' responses - alas, I believe my work wi-fi is blocking the ports Siri is trying to use

 

[Hamsterhjulet]

Working perfectly fine on my iPhone 16 Pro. Smooth as butter. Even fixed a few bugs I had on DB1: Crop text was misaligned (it’s now the crop icon), indexing is gone, automatic dark/light mode with sunset/sunrise is working again and setup talk to Siri notification badge is gone.

 

[minato21]

no issues so far on my 16 pro, can now add medications in the health app (before it gave you a infinite loading screen)

Framerate also feels a lot better, was slightly choppy in b1 now it’s completely smooth so far.

Keyboard so far seems reliable in terms of actually showing up. Loading emojis also seems instant whereas before it took a second or two to open.

So far so good.

 

[adrianlondon]

Same. Other shortcuts work fine but automations are busted.

Mine are working - iPhone 17. The notification that there are some appears after a reboot, and they trigger just fine.

Did yours sync and get set to "disabled" (first action in the relevant shortcut)? Worth checking, in case you haven't already.

After installing this on my phone, I can’t install apps on my watch. Anybody else?
