If you recently updated your iPhone to iOS 27 and keep seeing the message “Indexing in Progress,” you are not alone. Many users have noticed this message after installing the latest software update. The good news is that it is usually a normal process rather than a bug.
With iOS 27, Apple has rebuilt parts of its search infrastructure, which means your iPhone needs to re-index content stored on the device. This includes Messages, Photos, Mail, Notes, Files, and Spotlight Search results. During this process, some search results may be incomplete, Siri AI features may take longer to become available, and battery life can temporarily be affected.
Apple’s new search system automatically starts indexing after the update is installed. Reports indicate that iOS 27 performs a more extensive re-indexing process than previous releases.
In this guide, we’ll show you how to check the actual indexing status in iOS 27 and confirm whether your iPhone is still processing data in the background.

Check Indexing Status Through Siri & Search
One of the easiest ways to verify indexing activity is through the Search settings.
When indexing is still underway, iOS 27 may display a message indicating that search results are still being prepared.
- Open the Settings app.
- Scroll down and tap Siri & Search.
- Look for any indexing-related message or status indicator.
- If you see “Indexing in Progress,” your iPhone is still processing content.
- Wait until the message disappears.
Some users have reported that Apple added a small progress indicator for background indexing after updating to iOS 27.
Check Spotlight Search Results
Spotlight Search can reveal whether indexing has completed.
If results are missing from Messages, Photos, Mail, or Notes, indexing is likely still running.
- Swipe down on the Home Screen.
- Open Spotlight Search.
- Search for an older message, photo, note, or email.
- Compare the results with what you expect to find.
- If content is missing or incomplete, indexing may still be in progress.
Apple’s new search infrastructure rebuilds indexes for multiple apps after an update. Search results can remain incomplete until the process finishes.
Check Messages Search Indexing
Messages is often the easiest place to verify indexing progress.
Many users first notice indexing issues when searching for older conversations.
- Open the Messages app.
- Tap the search bar.
- Search for an old contact name or keyword.
- Scroll through the results.
- If you see messages indicating that more results will appear after indexing finishes, the process is still ongoing.
Message indexing can take additional time if you have a large message history stored in iCloud.
Check Battery and Device Activity
Background indexing often causes temporary increases in battery usage and device activity.
- Open Settings.
- Go to Battery.
- Review recent battery activity.
- Look for unusually high background activity after updating.
- Leave the device connected to Wi-Fi and charging when possible.
Users commonly report higher battery drain immediately after major iOS updates while indexing completes.
Let Your iPhone Finish Indexing Faster
If indexing seems stuck, there are a few things you can do to help the process complete more quickly.
- Connect your iPhone to a charger.
- Connect to a stable Wi-Fi network.
- Leave the device locked for several hours.
- Make sure Low Power Mode is disabled.
- Keep sufficient free storage available.
- Restart your iPhone if indexing appears frozen.
Many users report that indexing completes faster when the device remains plugged in and connected to Wi-Fi. Average completion times can range from a few hours to longer periods depending on storage size and data volume.
