Buttons
Most of the buttons you use with iPhone are virtual ones on the touchscreen. A few physical
buttons control basic functions, such as turning iPhone on or adjusting the volume.
Sleep/Wake button
When you’re not using iPhone, press the Sleep/Wake button to lock iPhone. Locking iPhone puts
the display to sleep, saves the battery, and prevents anything from happening if you touch the
screen. You can still get phone calls, FaceTime calls, text messages, alarms, and notications. You
can also listen to music and adjust the volume.
On iPhone 6 and iPhone 6 Plus, the Sleep/Wake button is on the right side:
