When your iPhone’s screen is off, that is considered the “Lock” mode of the device. Also referred to as “Sleep” mode, this indicates that the iPhone is turned on and able to receive notifications from your apps, such as a phone call or text message, but that the content on the screen is not currently visible.
The iPhone will enter this sleep mode after a pre-determined amount of time where you have not interacted with it.
This helps to conserve battery life, as the iPhone can use a lot of battery when the screen is turned on. It also minimizes the risk of pocket dials and makes it difficult for thieves or others to unlock the device if you have a passcode or fingerprint set.
But if you want the screen to stay on longer or enter sleep mode more quickly, the steps below will walk you through changing that setting.
