• 3 Insufficient Storage

iPhone rebooting loop might be due to insufficient storage on your iPhone. The storage problems are more common on older iPhone models. But it doesn’t rule out the newer models because storage depends on how much space you use, irrespective of the model.

• 4 Malware

Besides, you might get exposed to malware when using free public WiFi. So you might be facing iPhone restarting issues due to a possible malware that has infected your device.
