Why iOS 27 slows down even the new iPhone 18 Pro at…

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.

💡 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.

Apple & Amazon UK face revived $383 million price fixing lawsuit

A UK Competition Appeal Tribunal has revived part of a dismissed consumer lawsuit against Apple and Amazon, allowing claims that the 2018 agreement limited Apple product sales through Amazon’s marketplace to proceed. The case, originally filed in 2022, alleges price‑fixing and anti‑competitive practices that could have raised consumer prices. The tribunal rejected a claim about sales from other retailers, citing insufficient evidence. The revived suit could award up to £289 million ($383 million) if successful.

💡 The decision signals that regulators are willing to scrutinize tech giants’ distribution deals, potentially reshaping how major retailers and manufacturers collaborate. It also underscores the legal risks of anti‑competitive agreements in the digital marketplace.
