Can anyone give me some help on why my optimizing is stuck at 43% on after doing the iOS 27 update? Customer service couldn’t give any help saying to give it more time but it’s way over the amount of time they were saying it takes.
iPhone 16 Pro, iOS 27
If the 43% you’re seeing is the Search/Siri “Optimizing” progress after the update, that process can take quite a while. Apple says indexing after a software update can take hours or even days depending on how much data is on the iPhone. → About Spotlight indexing and search results on Apple devices - Apple Support
I’d leave the iPhone connected to power and Wi-Fi overnight, preferably while you’re not using it. That gives the indexing process the best chance to finish.
If it’s still sitting at exactly 43% after another day, restart the iPhone and check for any newer iOS 27 update under Settings > General > Software Update.
If you mean a different “Optimizing” screen, let us know where you see the 43% and we can narrow it down.
