Optimizing Search and Siri stuck at 33% after update

hat step can take a long time right after a big update, but 4 days is too long. Try: 1) Plug in the iPhone, connect to Wi-Fi, lock it and leave it overnight. 2) Restart it (press and quickly release Volume Up, then Volume Down, then hold the side button until the logo appears). 3) If still stuck, Settings > Apple Intelligence & Siri > turn Siri off, restart, then turn it back on. 4) Last step: Settings > General > Transfer or Reset > Reset Network Settings.T

There is no such location at Settings > Apple Intelligence & Siri in iOS 27. That information may have been useful for previous iOS versions and a common mistake when relying on an AI response to copy/paste the information provided there.

Yes, plugging your phone in overnight and connected to WiFi is recommended to allow the indexing to complete faster. I would also recommend the Force Restart, just make sure in the last step to hold the Side button until the Apple logo appears. It could take up to 15 seconds before you will see the Apple logo and you have to ignore anything else on the screen including the prompt to slide to power off.

Also be aware that the Search and Siri indexing seen in Settings will return from time to time even after it has initially completed.

• Spotlight indexes your device so that you can search its contents. Indexing happens when you first set up your device, after you install a software update or upgrade, and as data changes on your device. For example, the index updates when you install new apps that allow their content to be indexed, or you receive new email or text messages.

And finally 4 days is not necessarily too long as previously mentioned, especially if this was an update from iOS 26 or you are not charging overnight.

Thanks Mac Jim, you are right. That Settings path in my step 3 doesn't exist in iOS 27, please ignore it. The overnight charging on Wi-Fi and force restart are the steps to follow, and indexing can legitimately take a few days after a big update.
