The iPhone 7 might be a tiny mobile phone that you keep in your pocket, but it shares a lot of similarities with a computer. One of these similarities exists between “processes” that run on a laptop or desktop computer and on your iPhone. These are the application functions on the device that let you use the apps and features that make the iPhone so helpful.
When one of the processes for one of your apps gets stuck, or is not behaving properly, then your iPhone might start running slowly, or certain apps might stop working altogether. If you have searched on line for troubleshooting methods to fix this problem, then you most likely encountered a step that asked you to “restart the iPhone” or to perform a “soft reset on the iPhone.” Our tutorial below will show you how to do this.
How to Turn Your iPhone Off and On Again
The steps below were performed on an iPhone 7 Plus, in iOS 10. However, this method is the same for other iPhone models using iOS 10, as well as iPhone models running most other versions of iOS. Restarting your iPhone is something that you should only need to do occasionally. The iPhone is designed to remain on for very long periods of time, so it is best to only restart the phone if you are experiencing a problem that you think might be fixed in this manner.
Step 1: Locate the Power button on the top or side of your iPhone. The location will vary depending upon your iPhone model.
Step 2: Press and hold the Power button until it displays a Slide to power off button, as in the image below.
Step 3: Slide the button to the right to turn the phone off. It will take several seconds for the iPhone to turn off completely, and you may see a spinning circle of dashes at the center of the screen as the iPhone processes are terminated and the device is shutting off.
Step 4: Press and hold the Power button again to turn the phone back on. You will see a white Apple logo when it is turning on, as in the image below.
After a few seconds the phone will be back on and you can start using it again. Depending upon the password settings you have for your iPhone, you may need to re-enter your passcode before you begin using the device.
If your iPhone is running slow, or some apps don’t seem to be functioning properly, then you might be running out of storage space. Read our complete guide on deleting apps and files from your iPhone to see some common places you can look to gain back some of your storage.
