Your iPhone is stuck in an infinite boot loop. Every time the Apple logo shows up on your screen or when you thought you had a successful reboot, the screen goes dark again. This happens because your iPhone keeps restarting. This issue is one of the trickiest iPhone issues because there's a number of causes for this problem.
Before undertaking any of the more in-depth solutions below, there are a few fundamentals to give a go.
- Connect to a known functional, or different charger. Your phone may not be getting enough energy to complete boot.
- Perform a force restart. Consult the guide for your model if you are not familiar with this process.
- If you can get into the operating system, check for any software updates. This also includes app updates.
If your iPhone continues to restart endlessly, try using these tips.

Restore Backup
During the course of using your phone, something in the ones and zeroes that makes it run might have been lost, or changed in a way that renders your device unusable. This is usually a result of a botched update of an app or software.
To try to remedy this, reinstall the operating system. If your phone will stay booted for long enough, you can try this from within the settings menu. Otherwise, you'll need to get it into recovery mode to initiate this process.
If the update is unsuccessful, consider restoring a backup of your phone. If you're certain you have a recent backup, or are willing to sacrifice your data to regain use of your phone, proceed to restore. This will erase any data presently on your phone. If you would rather not erase the device, you can find other solutions to fix this problem.

Faulty Charge Port
The charge port and the connected interior flex cable are common points of failure on all iPhone models. It is prone to wear and easily exposed to the environment. This leads to inconsistent charging, and inability to maintain power for long enough to boot properly.
- Inspect your charge port using a flashlight for better visibility. It is common for bits of lint or rubbish to get caught in the port and compress with repeat charging. To verify, check the fit of your cable. Does the lightning plug sit flush with the bottom of the phone? It should.
- If there is debris in the port, use a non-conductive probe to clear it. Insert the point straight to the back and gently scrape out residual debris. Be mindful of the pins.
- A phone that only charges at particular angles, or intermittently in general, may need a new charge port assembly.

Faulty Battery
We are likely all aware that all rechargeable batteries degrade over time. This can lead to poor battery life. But batteries can fail in any number of other ways, which can lead to unexpected restarts.
You can check your battery health by going to Settings > Battery > Battery Health. Does it say Service? By Apple’s guidelines, anything with a capacity of less that 80% needs battery service, though it can detect other failures as well. If it says Service here, a new battery is a reasonable start.

Logic Board
The logic board is the hub for the vast majority of an iPhone's functionality. Any number of the small components on the board may have failed or become damaged, and is a safe bet that this is the reason for an iPhone to keep restarting.
