iPhone Restarting Every 3 Minutes? Find and Send Your Panic Log

⏱️ What a 3-Minute Restart Means

If your iPhone restarts on a steady timer, often about every three minutes, it's usually not random. iOS restarts the phone on purpose when it stops hearing from a part it watches, such as a sensor.

Each crash leaves a report on the phone called a panic log. Its file name starts with panic-full. That report is the best clue to what failed.

🔍 Common Causes

• After a repair: a loose or damaged cable. On many models, the sensors iOS watches sit on the charging-port cable, the power-button cable and the battery, so a careless screen or battery job can unseat them. See Problems After a Screen Replacement.
• After a drop: a damaged sensor cable or a loose connector.
• After liquid: corrosion on a cable or connector. See Water-Damaged Phone? What to Do in the First Hour.
• Charging-port cable, power-button cable or battery: these carry most of the sensors iOS watches, so they are the usual suspects.
• Logic board: less common. We don't do micro-soldering in-house, and we'll tell you straight if that's the issue.

We don't guess from the symptom alone. The panic log usually names the part that went quiet.

🧪 Quick Checks You Can Do

Phone frozen? Force restart it first. Steps by model: iPhone 8, SE (2nd and 3rd gen), and Face ID models, iPhone 7 and 7 Plus, iPhone 6s, SE (1st gen), and older. If your buttons don't work, you can restart without buttons.

• Update iOS if an update is waiting.
• Take off the case and unplug all accessories.
• Note when it restarts: on the charger, off the charger, or only when you use certain apps.
• If it only restarts after a repair elsewhere, keep any receipts and tell us what was replaced.
