There will be times in your iPhone’s life when you’ll need to reset the device. You have two ways to do that — a soft reset and a factory reset — and knowing when to use either method is nearly as important as knowing how.
Soft-resetting Your iPhone
Soft-resetting your iPhone is simply a way to restart the device. You don’t delete any data at all. It can be a handy way to resolve problems with an erratically behaving iPhone. If apps are crashing, your phone can’t recognize connected device that it’s worked on before or your iPhone completely locks up, a soft reset can set things right.
To soft reset your iPhone, press and hold the Home button and the Sleep/Walke button simultaneously for at least 10 seconds. You can let go of both buttons when you see the Apple logo appear on the iPhone’s display. Your iPhone will go through its startup routine and after a while — 30 to 45 seconds, usually — it will go back to your home screen. If you’ve set up a passcode, you’ll need to re-enter it after resetting your iPhone.
