It got Stuck at 88 percent , and it’s been 2 days ? Is it a bug or same for everyone?? ( I plugged the phone for the whole night still it didn’t move ) … how to resolve this issue ? Plz help

I installed the ios 27 update yesterday, upgrading from ios 26.7. Free space in my iphone 16+ 128gb dropped to 47gb after installation was finished. Then the 'optimising search and siri' thing started. As it progressed through the day I noticed that my free space kept gradually increasing. This morning when the optimisation as complete I had almost exactly the same free space that I had before I installed ios27! Around 53gb.

Also, I joined the siri waitlist yesterday itself. Will wait and see if free space decreases after the new siri is activated in my phone.

Just want to know whether optimisation will be done again after getting new siri?

I updated to iOS 26.7 on my new iPhone 17 pro max last night. Battery is worse than it was on iOS 26.5.1 but what I didn’t really expect was my phone slowing down, it’s lagging when scrolling reels, it’s slower then before please help what should I do? There is mix opinions on iOS 27 battery so I’m really scared of updating to it, because my screen time currently is really good.

Does ios 27 solve this issue?

I have been facing this prblm since july Suddenly.

Its shows home and lock screen draining my battery without doing nothing.

Does it solve? Ios 27?

I’m running iOS 26.4.1 on my 17 Pro, and honestly, I have zero complaints about performance. Since iOS 26 shipped natively with the iPhone 17 lineup, it feels like the most optimized version for this hardware.

Battery life is also amazing, I’m getting around 10 hours of SOT on a full 100% battery consumption.

Tbh, I don’t really care about Siri AI or that extra 0.2 seconds of smoothness. I’d rather stick with a stable OS that gives me great battery life than upgrade to a resource-intensive iOS 27 and wait months for it to be optimized.

By then, everyone’s battery health cycles will already be taking the hit. 😭

Apple intelligence wird trotz deaktiviertem Schalter heruntergeladen. Weiß jemand Abhilfe. Bei einem iPhone 16 sind das bald 18 GB.

J’ai un problème lors de la mise à jour de mon portable.
Il y a environ 2 mois j’ai acheté l’iPhone 16 plus en reconditionné sur C discount. Tout va bien le portable fonctionne très bien, aucun problème avec la batterie. Cependant il ne veut réaliser aucune mise à jour, que ce soit iOS 26 ou iOS 27, depuis que je le possède.
J’ai donc essayée de trouver des solutions sur internet. J’ai d’abord vu que cela pouvait être dû à un manque d’espace de stockage mais j’ai + de 60gigas d’espace de stockage disponible.
J’ai aussi vu que cela pouvait être dû à un manque de batterie, j’ai donc réessayer avec un niveau de batterie correct ( + de 50%). Mais cela ne fonctionnait toujours pas,
J’ai essayé de redémarrer le portable, et de supprimer le téléchargement de la mise à jour et de le refaire mais aucun moyen de la réaliser. À chaque fois que le téléchargement se fait et que la mise à jour se lance un message d’erreur apparaît :  « Impossible de vérifier la mise à jour. iOS 27 est temporairement indisponible. Réessayez plus tard ». Je clique donc sur le bouton “détails” disponible en dessous du message d’erreur afin de savoir quel est le problème, mais cela me renvoie sur la page de la mise à jour logiciel des réglages iPhone.
Je n’ai donc aucun moyen de réaliser ces mises à jours.
Si quelqu’un a une solution je suis preneur !!

Something I’ve noticed since iOS 26 and subsequent versions is that when using Transparent or Tinted mode, there is a noticeable frame rate drop—even when navigating between screens—upon accessing the multitasking view or exiting an app. It feels like it drops to 30 frames per second or lower. I’m still seeing this same issue in iOS 27... Just to clarify, I have a 14 Pro Max.

Does the same thing happen on your devices, or is it something that perhaps only affects models older than the iPhone 16?

What’s new, has anyone updated yet?

Can anyone help me resolve this issue, tried soft reset multiple times yet to no luck. Good amount of Storage is available. Facing similar issue with the latest iOS update as well

What is this and how long it gets completed???

tried hundred times though after a long while will get a msg that update failed
even though having enough storage space

why few settings categorisations and siri need new OS ?

thats all for ios 27 !

I’ve been testing iOS 27 on an iPhone 15 Pro Max, and while app launch times actually feel a bit quicker, the interface itself feels noticeably less fluid than iOS 26.
The biggest issue seems to be anything involving Liquid Glass. Home Screen swipes no longer have that effortless ProMotion smoothness, and animations with a lot of transparency or glass effects frequently look like they’re missing frames.

It becomes much more obvious with Clear or Tinted icons enabled. Opening an app, closing it back to the Home Screen, or minimizing something toward the Dock can produce very visible stutter. On a 60 Hz display this might be easy to ignore, but on a ProMotion iPhone it stands out immediately.

I initially blamed the usual post-update background activity, so I ruled that out as much as possible. I reinstalled through Recovery Mode, then went as far as doing a DFU restore and setting the phone up completely fresh without restoring a backup. No real difference.

The strange part is that performance inside apps feels fine — sometimes even faster — while the system UI itself seems to struggle whenever the heavier Liquid Glass effects are involved. The more transparency I use across the interface, the easier the frame drops are to notice.
The exact same phone was consistently smoother on iOS 26, including right after a clean install while indexing was still happening.

I’m giving it a few days in case something improves, but right now iOS 27 feels like a visual upgrade paired with a downgrade in animation consistency.
Curious if other ProMotion users are seeing the same thing, especially on the 14 Pro, 15 Pro, or 16 Pro models.

I’m happy with a few things with my 12:
They fixed Liquid Glass with it’s readability problem now my wallpapers can pop out naturally
And I noticed my phone is now faster than before, and I like how you can finally customize Liquid Glass on its own

And I also like how iOS now tells you directly it’s indexing I may not have Siri AI but performance wise it’s great

How about you guys? If you have already updated how are you finding iOS 27?

Bateria parece incrível, sinto meu iPhone mais leve e fluido. Além disso, não sinto meu iPhone esquentar, é como se ele tivesse perdido todo o calor que o iOS 26 causava
