It can happen to any one of us. Even the best of us need some time to recharge and to breathe. So does our iPhone. If you find that your iPhone performs more and more slowly, for sure, you need to reset it. The factory reset is a great solution that can be used to bring your iPhone back to a perfect activity. With the factory reset you return your iPhone to the status "new", because everything will be erased, for example music, pictures, apps and other data that was added in the past. The iPhone also returns to its original settings. All in all, the factory reset means you are completely erasing your data from the phone and starting it as a new one.
"Reset All Settings" simply means that it will reset the settings on your phone to their original state. You will not lose documents, files and any installed apps in the process.
Step 1: Navigate to Settings > General > Reset
Step 2: Rest All Settings
When prompted click on the 'Reset All Settings' button. A list of options will come up, click on the 'Reset All Settings' button again to continue.
This is to make sure that you confirm the action and the process should take no longer than 10 minutes.
If you have been paying attention to the screen of your iPhone, you would notice that the 'Reset All Settings' and 'Erase all Content and Settings' options are side by side. So, if you are the type of person who are always clumsy or just downright bad lucked, these data recovery steps using iRefone for Mac ( iRefone for Windows ) may be your saviour in the unfortunate instance that you accidentally erased everything on your phone.
