iOS 27.2 bug? "Optimizing Search and Siri" keeps restarting every day

Since updating to iOS 27.2 on October 26, all three of my iPhone 18 Pro Max show "Optimizing Search and Siri" (indexing) multiple times a day. It finishes, then starts all over again. It's a constant cycle now.


What I've already ruled out:


  • It's not one phone: all three of my 18 Pro Max do the exact same thing


  • It's not the account: each phone uses a different Apple Account


  • It's not my content: I don't store any photos on any of these phones, and each has fewer than 10 apps installed


  • It's not file transfers: I don't transfer anything to these phones, just basic everyday use


  • It's not impatience: I've left each phone plugged in, alone, with no activity, and indexing does finish — then it starts again later while I'm just using the phone

On iOS 27 and 27.1, this only happened once after the initial setup, and then never again. On 27.2, it's every day.


Anyone else on 27.2 seeing this loop? Any fix, or is this just waiting on an update?

I’ve had this loop since 27 came out. first couple updates it took nine days, then this most recent time (The one in October) I guess took a total of four days, but it took two days where I thought it was done and then it popped up the next day and it was stuck at 33% and then later in the day it went away and I hadn’t seen it since. now today was another update iOS 27.2.1 it popped up now it’s gone, but I know it’s gonna pop up again. Didn’t even have a percentage like always until about 24 hours after the update. It’s not very uniform some people it takes weeks some people it takes 24 hours. Some people never receive the percentage on the banner and some of us do,some people have said today’s update they never received a banner at all. This update the banner popped up right away. 27.2 it took about 30 minutes to show up. It is what it is. 🫩

Just as an example my iPhone 18 Pro Max had to index, sync etc. just under 300GB of data and it took over a week, probably 8 or 9 days. iOS 27.2 was released just 7 days ago it’s very possible you’re device is not finished with the background tasks.


In addition I helped speed the process by plugging my iPhone into a charger every night, connecting it to WiFi and locking it. This permits the iPhone to do more tasks uninterrupted.

A large amount of indexing is performed after updates, but you will see the message again when there is new content needing indexed.

  • 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.
