If you don't like using Siri, this iOS 27 feature may change your mind

The new Siri AI has what Apple calls "personal context understanding". Once you install iOS 27, you may notice a notification in the Settings app about "Optimize Search and Siri." This means your device is learning everything about you, from emails to messages. The process takes a while to complete (it will run faster when your phone is locked, charging and on Wi-Fi), but it's essential for Siri AI to work. With this knowledge about what's on your phone, Siri becomes much more powerful and smart.
