The situation when iPhone keeps rebooting (cyclic reboot), is familiar to many users. The smartphone turns on, the Apple logo appears, then the screen goes black—and the process repeats over and over again. This behavior makes the device practically unusable. Let's take a look. Why does my iPhone bootloop and how can I fix it?.
🔍 Common Causes of iPhone Reboot Loops
-
iOS update errors
Sometimes after installing a new firmware version or during an update, the system freezes and goes into a reboot cycle. -
Battery faults
An old or damaged battery may produce unstable power, causing your iPhone to shut down and restart. -
Corruption of system files
Installing hacked apps, viruses (during jailbreaking), or data recovery failures can cause a reboot loop. -
Hardware failures
The problem may lie in the motherboard, power controllers, or other microcircuits. -
Power button malfunction
If the Power button gets stuck or short-circuits, the phone may restart endlessly.
🛠 What you can try to do yourself
-
Forced reboot
For iPhones with Face ID: Quickly press "Volume Up," then "Volume Down," then hold the Power button until the Apple logo appears. This can sometimes help break the loop. -
Update or restore via iTunes (Finder)
Connect your iPhone to your computer, enter Recovery Mode, and try updating the system. If that doesn't help, perform a restore. -
Checking the cable and power supply
Sometimes the problem is related to the charger - it is worth trying the original cable and power supply.
⚡ When you can't do without service
If the iPhone continues reboot cyclically even after system restore, it's most likely a hardware issue. The service can perform the following:
-
Diagnostics of power supply and motherboard.
-
Check the battery and replace it if necessary.
-
Repair of power controller or starting circuits.
-
Complete restoration of the software part.
💡 How to avoid similar problems in the future
-
Install iOS updates only over a stable Wi-Fi connection and with sufficient battery power.
-
Use only original charging accessories.
-
Avoid questionable apps and jailbreaking.
-
Make regular backups of your data to avoid losing important information in the event of a failure.
