For mobile devices with detachable batteries, a soft reset simulates battery removal. A soft reset is performed on phones with non-removable batteries, such as the new iPhone 8 Plus, by turning the phone off and then turning it back on after a few seconds. Essentially, it turns off your gadget and then restarts it from scratch. A soft reset can also be used to shut down a device that has become frozen or unresponsive. This reset is considered safe since it will not damage any of your personal data saved on your device. Soft resets are frequently used to address minor app issues. On your new iPhone 8 Plus, here's how to make a soft reset (restart):
- For a few seconds, hold down the Side (Power) button until the Slide To Power slider displays.
- Slide to totally turn off your iPhone.
- Hold down the Side (Power) button for another 30 seconds until the Apple logo shows.
In iOS 11, the Settings menu has been included as a new option for restarting your device.
- Tap Settings from the Home screen to soft reset (restart) your iPhone 8 Plus using the Settings menu. This will open the Settings application. Locate and press the Shut Down option. The iPhone will be turned off if you do so. In a nutshell, go to Settings-> Shut Down.
This is a new feature in iOS 11 that wasn't present in earlier iOS devices.
