An iPhone boot loop happens when the phone repeatedly shows the Apple logo or restarts without reaching the Lock Screen or Home Screen. If you have an iPhone stuck in boot loop after an update or crash, start with a force restart. If the loop continues, connect the iPhone to a Mac or PC and use Recovery Mode; when Apple offers Update or Restore, try Update first because it attempts to reinstall iOS without erasing your personal data.
If the boot loop began after a drop, liquid exposure, battery replacement, or only happens while the iPhone is connected to power, do not assume it is a software problem. Those patterns can point to a battery, connector, or other hardware fault that needs service.

Part 1: What Causes an iPhone Boot Loop?
An iPhone stuck in a boot loop can come from either software or hardware. The symptom alone does not prove which one is responsible, so the fastest approach is to match the loop to what happened immediately before it started.
| What happened before the loop? | What it can suggest | Best first action |
|---|---|---|
| iOS update or restore was interrupted, or storage was critically low | Incomplete or unstable iOS installation | Force restart, then Recovery Mode Update |
| The iPhone can reach Settings for a short time before restarting | Storage pressure, app/data instability, or a recoverable software issue | Back up, free storage, remove a recent problematic app, and update iOS |
| The loop began after jailbreaking or unsupported system modification | System files or startup components may have been altered | Use an official update/recovery path; avoid further unsupported modifications |
| The iPhone loops only when plugged in, or the issue began after a drop/battery repair | Power, battery connection, flex cable, or other hardware fault | Stop repeating software restores and arrange hardware diagnosis |
| The iPhone is detected in Recovery Mode by Finder or Apple Devices | Computer-based recovery is available | Choose Update before Restore |
Low storage is especially important when a boot problem starts during an iOS update. Apple has documented recovery cases where a device can become stuck at the Apple logo after an update when storage is low. Hardware clues matter just as much: community repair cases also show that a loose battery connection or other internal damage can produce a boot loop that software repair will not solve.
Part 2: 6 Ways to Fix an iPhone Stuck in a Boot Loop
Work from the least disruptive fix to the most destructive one. The order below puts non-erasing options first and clearly separates software repair from hardware service.
Fix 1: Force restart the iPhone
A force restart is the quickest iPhone boot loop fix to try because it can break a temporary startup crash without deleting content.
The same force-restart sequence for iPhone 8 and later applies to an iPhone 13 boot loop, as well as newer Face ID models.
For iPhone 8 and later:
- Quickly press and release Volume Up.
- Quickly press and release Volume Down.
- Press and hold the Side button. Release it when the Apple logo appears.
For iPhone 7 and iPhone 7 Plus: Press and hold the Side and Volume Down buttons until the Apple logo appears.
For iPhone 6s, iPhone SE (1st generation), and earlier: Press and hold the Home and Side/Top buttons until the Apple logo appears.
Fix 2: Use Recovery Mode and choose Update before Restore
If the iPhone reboot loop continues, connect it to a Mac or PC. On a current Mac, use Finder. On Windows, use the Apple Devices app. Older systems may use iTunes.
- Connect the iPhone with a reliable USB cable and open Finder or Apple Devices.
- Put the iPhone into Recovery Mode using the button sequence for your model.
- When the computer offers Update or Restore, choose Update first. Update attempts to reinstall iOS while keeping personal data.
- If Update fails and the boot loop remains, repeat the process and choose Restore. Restore reinstalls iOS and erases the device.
Important: If the software download takes long enough for the iPhone to leave the recovery screen, let the download finish and then put the device back into Recovery Mode.
Apple's current Recovery Mode instructions explain the Update/Restore flow and the data-loss difference.Fix 3: Use Dr.Fone Standard Repair for a software-related boot loop
If Recovery Mode Update does not resolve a software-related loop, Dr.Fone - System Repair (iOS) provides a guided firmware-repair workflow. Its Standard Repair mode is designed to preserve personal data. Advanced Repair erases device data, so treat it as a later fallback rather than the default.
Fix iOS issues, no data loss.- One-click repair for all iOS problems.
- Solve recovery mode, Apple logo, black screen, etc.
- Upgrade or downgrade iOS without iTunes
How to use Standard Repair for an iPhone boot loop:
-
Step 1 Open System Repair and choose Standard Repair
Launch Dr.Fone, open Toolbox > System Repair, connect the iPhone, choose iPhone, select iOS Repair, and then choose Standard Repair.
-
Step 2 Enter Recovery Mode and download firmware
Follow the on-screen Recovery Mode instructions, or use Guide if the iPhone is unresponsive. Select a compatible firmware package and click Download.
-
Step 3 Repair iOS and keep the iPhone connected
After the firmware is ready, click Repair Now. Keep the iPhone connected until the process finishes, then choose Done.
Before you continue: The current Dr.Fone Guide notes that system repair can update the device to the latest iOS version; a jailbroken device may return to a non-jailbroken state, and a previously unlocked device may be re-locked.
Fix 4: Restore the iPhone, then restore a backup
If non-erasing repair attempts fail, Apple’s Restore option can reinstall iOS from scratch. This step erases the iPhone. After the restore finishes and the device reaches setup, you can restore an iCloud or computer backup.
Do not treat "Restore Backup" as the boot-loop repair itself. A backup is applied after the phone is working well enough to complete setup.
Fix 5: Check storage or a recent app if the iPhone boots intermittently
If the iPhone stays on long enough to reach Settings, use that window to protect data and remove obvious triggers before the next restart:
- Back up the iPhone immediately.
- Go to Settings > General > iPhone Storage and free meaningful space if storage is nearly full.
- Remove a recently installed or repeatedly crashing app if the loop began after that app was added or updated.
- Install a current stable iOS update once you have enough free storage and power.
If the phone never reaches Settings, skip this fix; app cleanup is not practical during a continuous boot loop.
Fix 6: Get Apple or hardware service
Move to hardware diagnosis when the iPhone restart loop persists after software recovery, or when the pattern points to physical damage. Strong clues include a boot loop after a drop or liquid exposure, a loop that happens only while charging, recent battery or screen work, abnormal heat, or repeated restore errors.
Apple or an Apple Authorized Service Provider can test the battery, connectors, logic board, and other components. Avoid repeatedly erasing or reflashing the phone when the evidence points to hardware.
Part 3: How to Reduce the Risk of Another Boot Loop
- Keep free storage available before major iOS updates. Do not start a large update when storage is almost full.
- Use stable power and a reliable cable. Avoid disconnecting the iPhone during an update, restore, or firmware repair.
- Keep regular backups. A current iCloud or computer backup reduces the cost of a future Restore.
- Avoid unsupported system modifications. Jailbreak-related or other low-level changes can complicate recovery.
- Take hardware symptoms seriously. If restart loops begin after physical damage or battery work, get the device inspected instead of repeating software fixes.
Backup tip: Once the iPhone starts normally again, make a current iCloud or computer backup before the next major update or repair. A recent backup reduces the data-loss impact if a future recovery requires Restore.
Conclusion
For an iPhone stuck in a boot loop, start with a force restart, then use Recovery Mode and choose Update before any erasing option. Dr.Fone Standard Repair is an optional guided path for a software-related boot loop and is designed to preserve personal data, while Apple Restore and Dr.Fone Advanced Repair erase data. If the loop follows a drop, battery repair, or only occurs while connected to power, hardware service may be the right next step.
FAQs
-
1. What causes an iPhone to get stuck in a boot loop?
Common causes include an interrupted iOS update, critically low storage during an update, corrupted system files, unsupported system modifications, or hardware faults involving power, battery connections, internal flex cables, or the logic board. -
2. Can I fix an iPhone boot loop without losing data?
Sometimes. A force restart does not erase data, Apple Recovery Mode Update attempts to reinstall iOS without erasing data, and Dr.Fone Standard Repair is designed to preserve personal data. Apple Restore and Dr.Fone Advanced Repair erase device data. -
3. How to fix iPhone boot loop without computer?
Without a computer, your main safe options are to charge the iPhone and try the correct force-restart sequence. If the loop continues, computer-based Recovery Mode, a repair tool, or hardware service is usually required. -
4. Does an iPhone boot loop always mean hardware failure?
No. Many boot loops are software-related, especially after an update. Hardware becomes more likely when the loop starts after a drop, liquid exposure, battery or screen repair, or only occurs while the phone is connected to power.
