Sleep/Wake vs Side button
The Sleep/Wake button and the Side button are the same thing. The button is used to put your iPhone to sleep, turn it on or wake it, and lock it. On some iPhone models, the button is also used to turn off the device.
The Sleep/Wake button is located on the upper right side of the device. On older models, such as the iPhone SE, iPhone 5s, iPhone 5c, and iPhone 5, the button is on the top edge. When you press the Sleep/Wake button once, your iPhone goes into standby mode or Auto-Lock, which saves battery power when you're not using your device. You can still receive incoming calls and messages, but the screen powers down. Press the Sleep/Wake button again to wake your iPhone.
To turn off your iPhone, press and hold the Sleep/Wake button until the red slider appears on the screen. Then, drag the slider to the center of the screen to turn off your device. On newer iPhones without a Home button, you need to press and hold the Side button and either Volume button until the sliders appear, and then drag the Power Off slider.
To turn on your iPhone, press and hold the Side or Sleep/Wake button until the Apple logo appears.

Turning off an iPhone X
The iPhone X has done away with the Home button, so the process of turning it off is a little different from previous models. The button that puts your iPhone to sleep or wakes it up is now called the Side button, previously known as the Sleep/Wake button. You can find it on the upper right side of your iPhone.
To turn off your iPhone X, press and hold the Side or Sleep/Wake button until the red slider appears on the screen. Then, drag the slider to the centre of the screen to turn off your device. Your iPhone will now be shutting down.
If you have an iPhone X, you can also shut it down by pressing and holding the Side button and either Volume button simultaneously until the sliders appear. Then, drag the Power Off slider.
It's important to note that putting your iPhone to sleep is different from turning it off. When you press the Sleep/Wake button once, your iPhone goes into standby mode or Auto-Lock, which saves battery power when you're not using it. The screen powers down, but you can still receive incoming calls and texts. To wake your iPhone from sleep mode, simply press the Sleep/Wake button again.
