iOS 15.8.4 is the security-update branch Apple maintains for older devices that can't run iOS 16 or later (iPhone 6s, 6s Plus, SE 1st gen, 7, 7 Plus, and iPod touch 7th gen). To install it: 1) Back up to iCloud or to a computer first. 2) Plug into power and connect to Wi-Fi. 3) Go to Settings → General → Software Update and wait for the update to appear. 4) If only an iOS 16+ option shows, it means your device supports the newer track - tap "Other Available Update" or scroll down for security-only update. 5) Tap Download and Install, enter your passcode, and let the device restart.
If the update fails, free up at least 5 GB of storage and retry over a stable network. Older iPhone running slow even on iOS 15? Battery replacement often restores performance - we do it in 1 hour at our Dubai workshop.
