iPhone Slow After Updating to iOS 26? Do This First (2026 Fix)

If your iPhone feels slow after updating to iOS 26, don’t panic — this is completely normal after a major update. When you install a big iOS version (like jumping to iOS 26), your iPhone spends the next 24–48 hours reindexing photos, optimizing apps, rebuilding system caches, syncing data, and cleaning up old files. This background work can make your iPhone feel laggy, warm, or even drain battery faster. THE FIX: 1. Leave your iPhone plugged in and on Wi-Fi for 24–48 hours. 2. Avoid heavy gaming or editing during this time. 3. After the system finishes optimizing, performance usually jumps back to normal.
