How to Fix iPhone Stuck on 'Verifying Update'
What the 'Verifying Update' screen means
After your iPhone downloads an iOS update, it does not install it right away. First it enters the verification phase: the phone contacts Apple's servers and checks the update package's cryptographic signature to confirm the file is genuine, complete, and untampered with. The spinning indicator on the 'Verifying Update' screen is that handshake happening.
A few minutes of spinning is completely normal. With a major iOS release on a slower connection, verification can legitimately take 15 to 20 minutes — the update file is large and millions of other iPhones are hitting Apple's servers at the same time.
The screen becomes a problem when it spins for an hour or more with no progress. That means the handshake failed silently somewhere: a shaky Wi-Fi connection dropping mid-check, Apple's servers overloaded, a corrupted or incomplete download failing its integrity check, not enough free storage to unpack, or a software glitch on the phone itself. Nothing is installed yet at this stage, so the phone is safe — it just needs the verification to complete before the real install can begin.
Common causes
- Slow or unstable Wi-Fi: verification talks to Apple's servers the whole time — dropouts and weak signals stall the check.
- Apple's servers are overloaded: release days and hours bring huge traffic spikes; Apple's System Status page shows when this is happening.
- Corrupted or incomplete download: an interrupted download fails the integrity check, and the phone retries it silently instead of telling you.
- Not enough free storage: the update needs 5 to 8 GB of free space to unpack — a nearly full phone can hang at verification.
- Low battery or a software glitch: iOS holds back the install below 50 percent battery unless charging, and a glitched update state sometimes just needs a restart to clear.
How to fix the 'Verifying Update' hang — step by step
Work through these in order. Most stuck verifications clear up in the first three steps.
- Wait at least 15 minutes before doing anything. Verification normally takes a few minutes, but with a major iOS release on a slower connection it can run 15 to 20 minutes. Leave the phone alone on its charger while you wait, and do not interrupt the process.
- Connect to strong Wi-Fi and plug into power. Go to Settings, Wi-Fi and join a strong, trusted network — move closer to the router and avoid public hotspots with captive login pages. Plug the iPhone into its charger: iOS requires the battery at 50 percent or more, or the phone charging, before it will install.
- Force-restart the iPhone. On iPhone 8 and later: press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button until the Apple logo appears. On iPhone 7, hold Volume Down and Sleep/Wake together. On iPhone 6s and earlier, hold Home and Sleep/Wake together. This is safe during verification — the phone boots back to its current iOS. Then retry the update in Settings, General, Software Update.
- Free up storage space. Open Settings, General, iPhone Storage and check what is free — an iOS update typically needs 5 to 8 GB of free space to unpack and install. Use the recommendations on that screen: offload unused apps, delete large Messages attachments, move photos and videos to iCloud Photos or a computer, and clear Safari website data in Settings, Safari.
- Delete the stuck update and download it fresh. Go to Settings, General, iPhone Storage, scroll to the iOS update entry (named after the iOS version), tap it, and choose Delete Update. Then go back to Settings, General, Software Update and choose Download and Install again on strong Wi-Fi with the phone plugged in.
- Install the update from a Mac or PC. Connect the iPhone to the computer with a cable. On a Mac, open Finder, select the iPhone in the sidebar, and click Check for Update. On Windows, open iTunes or the Apple Devices app, select the device, and click Check for Update. The computer downloads the full update image itself and installs it directly, bypassing phone-side Wi-Fi, storage, and download problems.
Did this fix it? Quick checklist
- The phone sits on strong Wi-Fi and stays plugged into power
- At least 8 GB of free storage is available before downloading
- Verification finishes within 20 minutes and the install begins
- The iPhone shows the Apple logo with a progress bar (install running)
If the update still will not verify after a fresh download, steps 1 through 5 rule out the phone side — step 6 (install from a computer) is your most reliable path forward. If a computer install also fails, book a visit to an Apple Store or authorized repair provider: the phone may need a restore or a hardware check.
Frequently asked questions
How long should 'Verifying Update' normally take?
A few minutes is normal — and with a major iOS release on a slower connection, up to 15 or 20 minutes. If the spinner has been going for more than an hour with no progress, the verification is genuinely stuck and you should work through the fixes above.
Will force-restarting the iPhone during verification cause damage?
No. During verification nothing has been changed on the phone yet — the update file is only being checked. A force restart boots the phone back to its current iOS safely. You may need to re-download the update afterward, but your data is untouched.
Why does my iPhone need Wi-Fi to verify an update?
Verification checks the update package's cryptographic signature with Apple's servers to confirm it is genuine and complete. That handshake needs an active internet connection, which is why weak or drop-prone Wi-Fi stalls the screen and why verification will not work on cellular data alone.
Is it safe to unplug the iPhone while it says 'Verifying Update'?
Yes — during the download and verification phases nothing is being installed, so unplugging is harmless. Just keep it plugged in when the actual installation begins (Apple logo and progress bar), because interrupting that phase is what can leave the phone in recovery mode.
What if my iPhone gets stuck on 'Verifying Update' every time?
Install from a computer instead — Finder, iTunes, or the Apple Devices app downloads the full update image and flashes it directly, skipping the phone's verification bottleneck entirely. If a computer install also fails, the phone may have a deeper software or hardware issue and deserves a look at an Apple Store.
