The so-called Hard Reset should be carried out only in extreme cases. This type of device reboot is applied if the smartphone has stopped responding to user actions and has corrupted.
In all other cases, you should perform a standard device shutdown by holding down the Power button (Side button).
Hard reset allows you to restart the iPhone, but on different models it is carried out in different ways.
iPhone X, iPhone 8 and iPhone 8 Plus
In the latest generation of smartphones, Apple has changed the way to quickly reboot the device. Now for this you need:
1. Press and release the button volume up.
2. Press and release the button volume down.
3. Hold and hold side button before the Apple logo.
You need to do this fairly quickly with a minimum delay between clicks.
iPhone 7 and iPhone 7 Plus
These devices use a slightly different method of rebooting. For this, for the first time, it was not necessary to use the Home button under the display.
Recall that starting with the iPhone 7, this key has ceased to be a physical button and is a touch button, and the Taptic Engine works out the feedback after pressing it.
In the event of a freeze, the touch button will not respond to user actions.
So for Hard Reset you need to hold down the buttons volume down and Power before the Apple logo.
iPhone 6s, iPhone 6s Plus and earlier
In all iPhone models from the very first to devices released in the spring of 2016 (iPhone SE) inclusive, Hard reset is performed the same way.
To reset, hold the button Home and key Power before the Apple logo.
This reboot method works on all iPad and iPod Touch models.
