Steps
Estimated time: 20-60 minutes
- 1
Check basic conditions
Verify you have a stable Wi‑Fi connection, a device with sufficient battery, and enough storage for the update. Move away from weak networks, connect to power, and clear space if needed.
Tip: If possible, switch to a fast home network and disable any VPNs during the update. - 2
Force restart the iPhone
Forced restarts can clear transient glitches. The method varies by model—generally, press and quickly release Volume Up, then Volume Down, then hold the Side button until the Apple logo appears.
Tip: Don’t force restart repeatedly; use it as a first corrective step. - 3
Retry the update OTA
Go to Settings > General > Software Update and retry. If prompted, choose Install Now and stay on power/or plugged in during the process.
Tip: Avoid using cellular data for large OS updates. - 4
Reset network settings if needed
If the update stalls due to connectivity, reset network settings: Settings > General > Transfer or Reset [Device] > Reset > Reset Network Settings.
Tip: You will need to rejoin Wi‑Fi networks afterward. - 5
Try updating via Finder/iTunes
If OTA fails, connect the iPhone to a Mac or PC and update via Finder (macOS 10.15+) or iTunes (older macOS).
