To switch off an iPhone, the general method is to press and hold the Side button and either one of the Volume buttons simultaneously until the "Slide to Power Off" slider appears on the screen. Then, slide the slider to the right to turn off the iPhone. Alternatively, you can turn off the iPhone through the Settings app by navigating to Settings > General > Shut Down, then dragging the power off slider. For iPhones with a Home button (older models), press and hold the Side button alone until the slider appears, then drag it to turn off. These methods work for most recent iPhone models including iPhone X and later, iPhone 11, 12, 13, 14, 15, and 16. To recap:
- For Face ID models (no Home button): Hold Side + Volume button, then slide to power off.
- For Home button models: Hold Side button, then slide to power off.
- Or go to Settings > General > Shut Down and slide to power off.
Pressing the Side button alone will not power off the phone; you need to use the combination with Volume buttons or use the Settings method to power down. This approach is confirmed by Apple Support and multiple instructional videos as of 2025.
