A force restart can help when an iPhone's system stops responding. The procedure depends on the model.
If the iPhone is unresponsive and cannot be turned on or off, try a force restart.
Note: The steps depend on the model. To identify yours, see Apple's Identify your iPhone model support article.
If it still will not restart, see Apple's If your iPhone will not turn on or is frozen. If it works incorrectly after restarting, consult iPhone Support.
