How to Lock My iPhone

The best way to avoid making unintended calls on your iPhone is to engage the auto-lock feature. The display goes to black, extending the battery life of the phone. By default, the auto-lock setting locks the iPhone automatically after one minute, however you can choose to auto lock after two, three, four or five minutes. Disable the feature by choosing "Never." When the iPhone is locked, you can still receive calls and text messages and listen to music. The auto-lock does not lock your iPhone from access by others. To do that, enter a passcode for the device.

Instructions

1. Press the "Sleep/Wake" button on the upper right edge of the iPhone to lock it manually.

2. Press "Settings" on the iPhone home screen. Tap "General." Scroll to "Auto-Lock" and tap it. Select one of the times or "Never." Press the "Home" button centered beneath the display to return to the home screen.

3. Press "Settings" on the iPhone home screen and select "General." Tap "Passcode Lock." Tap "Turn Passcode On" at the top of the screen. You are prompted to enter a four-digit numerical code, twice. Press the "Home" button to return to the iPhone home screen. Each time the iPhone "wakes," you must enter your new passcode to access the iPhone features. This protects you from data and information theft should the iPhone ever be stolen.
