Why iOS 27 slows down even the new iPhone 18 Pro at first
AI-summarised brief · reviewed before publication
Apple reports that new iPhone 18 Pro models and recent iOS 27 updates experience noticeable slowdowns due to extensive Spotlight and Siri AI indexing. The process, which scans files, apps, emails, contacts, photos, and more, can take hours or even days, especially on devices with large data sets. Users can accelerate completion by pausing usage, charging, and staying on Wi‑Fi, though the initial wait remains the most effective remedy. Apple acknowledges the delay and suggests incremental indexing will be faster once the initial build finishes.
💡 Why It Matters
- · The indexing slowdown underscores how deep system integration can temporarily hinder device performance, affecting user experience during critical early use.
- · It highlights the trade‑off between comprehensive data search capabilities and immediate responsiveness in modern smartphones.
