We've spent years with the iPhone and discovered countless tips and tricks to get the most out, but it's always good to know the basics. Something everyone needs to know is how to restore an iPhone. The steps were exactly the same on all devices up to the iPhone 6S Plus, but things changed a bit with the release of the iPhone 7 and 7 Plus and then changed again with the iPhone X.
If you upgraded from a previous iPhone model to the iPhone 8 or the latest iPhone XS Max, but never had to restore it, you can be lost on how to start the process. Don't worry, we're here to explain how to reset your iPhone to restart it and how to force restart when the phone doesn't respond. We also describe the differences between a restart, a soft reset and a factory reset.
How to reset your iPhone (soft reset)
The easiest way to restore your iPhone is to reverse it. This method is often referred to as a "soft reset", which means that you will not lose any data and nothing will be deleted from your phone. The best time to make a soft reset is when the phone goes a little slower than usual, an app doesn't open or doesn't work properly, or any other relatively small problem has occurred, but your iPhone is still responsive.
Step 2: Leave your finger on the slider and then pull to the right.  Step 3: When there is nothing on the screen and it turns black, press and hold the Sleep / Wake button again until the Apple logo appears.
Alternatively, provided you have iOS 11 or later installed, go to General> Settings and scroll to the bottom where you find Turn off . When you press Shut Down you will see the slider Slide to Power Off . You can then proceed to step 2 above.
How to force to restore your iPhone
Another way to restore your iPhone is to do what Apple officially calls "Force Restart." Again, no important data will be lost. A force restart is recommended when your iPhone does not respond completely. Examples of this include times when your iPhone screen turns black (even though it is turned on), the screen freezes or your iPhone is encountering a problem at startup.
The exact way to perform a power start differs between older iPhone models and the iPhone 7 and later. Instead of a traditional home button, the newer iPhones have a Home / Touch ID sensor, which is not used to start a power start and, as we discussed in our iPhone X features, Apple went away with the home / touch ID sensor in iPhone X for the benefit of the new Face ID.
