Charge it, check the cable, case, buttons, port, heat, and damage, then try a force restart; if that fails, use recovery mode and choose Update before Restore to give your data the best chance of surviving. Stop and arrange service first if the phone is hot, swollen, wet, badly damaged, or began restarting after a drop. ## Is your iPhone truly stuck in a boot loop? A true boot loop repeats the same cycle: the Apple logo appears, the phone begins starting, the screen goes black or returns to the logo, and the cycle continues. The iPhone may never reach the Lock Screen or Home Screen. ```text Apple logo appears, the iPhone restarts, and the cycle repeats before the Home Screen ``` Symptom One restart is not necessarily a fault. An iPhone can restart once after installing iOS, recovering from a crash, or completing a normal update. A completely flat battery may show the Apple logo briefly and then shut down; that is different from a repeating cycle after the phone has had time to charge. An overheated iPhone may shut down or refuse to start until it cools. Let it return to room temperature instead of repeatedly trying to turn it on. A stuck update screen is a separate case. If you see an Apple logo with a progress bar that is still moving, leave the iPhone connected to power and give the update time to finish. Do not interrupt a progressing update unless Apple’s support instructions for your situation say to do so. If the bar has not moved for a long time and the phone repeatedly restarts, treat it as a boot problem and continue with the checks below. ![An iPhone remains on its startup screen without reaching the Lock Screen.](https://tse1.mm.bing.net/th?q=iPhone%20stuck%20on%20startup%20screen%20photo&w=624&h=352&c=7) ## What should you check before forcing a repair? These steps apply to iPhones running current or recent versions of iOS, including models with Face ID, an Action button, or a Home button. You do not need Administrator or `sudo` access for checks on the iPhone. A computer becomes relevant only if you later use Finder or iTunes. A force restart does not normally erase data, but recovery-mode Restore does. Before you start, connect the iPhone to a dependable wall charger and check whether it can remain on while charging. Also think about what happened immediately before the problem: an iOS update, a drop, liquid exposure, a new accessory, or unusual heat. 1. Connect the iPhone to a dependable wall charger for at least 30 minutes. Use an Apple or reputable, undamaged cable and power adapter, and try a different outlet if needed. 2. Remove the case and any accessory attached to the phone. A tight or damaged case can hold a button down. 3. Inspect the charging port for lint, bent contacts, corrosion, or other debris. Do not push metal into the port or pour liquid into it. If debris is packed inside, have it removed safely. 4. Check that the side, volume, and Action buttons move normally and are not jammed. A stuck button can trigger repeated restarts or interfere with startup. 5. Think about what happened just before the problem: a drop, exposure to liquid, an iOS update, a new accessory, or unusual heat. Stop charging and stop pressing buttons if the iPhone is unusually hot, its screen or back is lifting, the battery appears swollen, it smells unusual, or it has liquid or serious physical damage. Keep it away from heat and arrange Apple or authorized service. ## Try these fixes in order, starting with a force restart A force restart is the safest active fix and normally leaves your photos, messages, and apps in place. Use the combination that matches your iPhone. 1. For iPhone 8 or later, including iPhone SE (2nd generation and later), press and quickly release Volume Up, press and quickly release Volume Down, then press and hold the Side button. Release it when the Apple logo appears. 2. For iPhone 7 or iPhone 7 Plus, press and hold the Side button and Volume Down together until the Apple logo appears. 3. For iPhone 6s or earlier, including iPhone SE (1st generation), press and hold the Home button and the Side or Top button together until the Apple logo appears. The screen can stay dark briefly before the logo returns. If the iPhone reaches the Home Screen, leave it connected to power and watch it for several minutes. If it loops again, use recovery mode with a Mac or Windows PC. 1. Update the Mac through System Settings or System Preferences, if needed. On Windows, install or update the Apple Devices app; on older systems, use the latest available iTunes. 2. Connect the iPhone to the computer with a reliable cable. 3. Open Finder on a Mac running macOS Catalina or later. Open the Apple Devices app on supported Windows systems, or iTunes on older Windows or macOS versions. 4. Put the iPhone into recovery mode using the same model-specific button sequence, but keep holding the final button after the Apple logo appears. Release it when the recovery screen shows a computer and cable. 5. Select the iPhone in Finder, Apple Devices, or iTunes. When the choice appears, select `Update`, not `Restore`. ```text The computer downloads and reinstalls iOS while attempting to keep personal data, and the iPhone starts normally. ``` Expected result The download can take long enough for the iPhone to leave recovery mode. If that happens before the download finishes, let it complete, then repeat the recovery-mode sequence and choose `Update` again. If `Update` fails, the computer reports an error, or the iPhone returns to the recovery screen, hardware or deeper software damage may be involved. `Restore` erases the iPhone and installs a fresh copy of iOS. Use it only after Update fails, or when you have a current backup and accept the loss of data that is not backed up. Do not choose `Restore` merely because the phone is inconvenient to restart. It is an erasing step, and recovery mode cannot guarantee that an unbacked-up photo or file can be recovered. ## How do you know the problem is actually fixed? The repair has probably worked when the iPhone reaches the Lock Screen or Home Screen, remains on while connected to power, and does not restart during ordinary use. Test it for a while rather than treating one successful startup as proof. 1. Unlock the iPhone and check that your photos, messages, contacts, and other important data are present. 2. Keep it connected to power and confirm that the battery percentage rises instead of repeatedly falling or restarting. 3. Disconnect it and use ordinary functions such as Wi-Fi, the camera, and a few apps. Avoid restoring or deleting anything until you know what data is present. 4. Back it up immediately using iCloud or a computer. For iCloud, open the following path and select `Back Up Now`: ```text Settings > [your name] > iCloud > iCloud Backup > Back Up Now ``` Settings path If you use a computer, make an encrypted local backup in Finder, Apple Devices, or iTunes if you want health and activity data included where supported. Confirm that the backup finishes and shows a recent date. If the iPhone loops again, do not repeatedly erase it. Return to recovery mode and try Update if you have not already done so. If Update already failed, preserve the backup information you have and contact Apple Support or an authorized provider. ## When repeated restarts mean it is time for service A boot loop can come from iOS, a nearly full storage device, a failed battery, charging-port damage, or another hardware fault. Service is the safer choice when the evidence points beyond a simple software crash. Arrange Apple Support or an Apple Authorized Service Provider if: - The restarts began immediately after a drop, bend, liquid exposure, or other physical event. - The battery is swollen, the display is lifting, or the phone becomes hot unusually quickly. - The charging port is loose, corroded, visibly damaged, or works only when the cable is held at an angle. - The iPhone restarts even after a successful Update or a Restore. - It cannot stay on long enough to back up, or it repeatedly fails to charge with known-good accessories. - The phone has very little free storage and continues restarting after it briefly starts. Storage failure or severe system corruption may require repair. If the iPhone manages to start, you can look for crash evidence here: ```text Settings > Privacy & Security > Analytics & Improvements > Analytics Data ``` Settings path Repeated files with names such as `panic-full` can indicate a kernel panic, often associated with hardware or a low-level system problem. A single report does not prove that a particular component is bad, so do not replace parts based only on its filename. Share the repeated reports and the timing of the restarts with Apple or the repair provider. Tell the technician whether the phone was dropped or wet, whether Update or Restore was attempted, and whether you have a backup. If the battery is swollen or the phone is hot, do not keep charging it while waiting for help. ## Conclusion Once the iPhone starts, back it up before investigating the cause. After your data is safe, install any available iOS update, check free storage, and remove or update an app installed just before the restarts. If the loop returns or the phone shows physical warning signs, stop troubleshooting and arrange Apple or authorized service rather than risking an erase or further damage. ## Frequently Asked Questions ### Will a force restart erase my iPhone? No. A force restart is designed to restart an unresponsive iPhone and normally does not remove personal data. Recovery-mode Restore is the step that erases the device. ### Should I choose Update or Restore in recovery mode? Choose Update first. It reinstalls iOS while attempting to preserve your data. Choose Restore only if Update fails or you have a usable backup and accept that the iPhone will be erased. ### Can a full iPhone cause a boot loop? Yes. Very low available storage can prevent iOS from completing startup or an update. If the phone starts, back it up immediately and check storage before deleting anything. If it cannot stay on, recovery mode or service may be needed.
