How to prevent your iPhone screen from turning off automatically

By , Mar 9, 2017

For optimal battery savings and security, you typically want your iPhone to lock automatically when it sits idle after a long period of time, just in case you happen to leave it unlocked and unattended somewhere.

On the other hand, sometimes you don’t want your iPhone to lock automatically, and there’s a setting in iOS that can prevent it from happening. We’ll show you how to enable it in this tutorial.

Why would you turn Auto-Lock off?

Although most people want Auto-Lock turned on because it helps conserve power and prevents nosy people from finding your unlocked device and going through your stuff, some might opt to prevent their device from locking automatically for various reasons.

One of the most common reasons has to do with AirPlay mirroring, during which you don’t want your device to lock up on you as this will interrupt the flow, forcing you to unlock your device again and restart the AirPlay stream.

Another reason to disable Auto-Lock is if you read a lot of books or websites on your device and hate when your display’s back light always goes dim on you while you’re in the middle of trying to read.

No matter the situation you’re facing, disabling Auto-Lock is a simple task and is often the solution to some of these common woes.

How do I stop my iPhone screen from turning off?

If you’ve decided to turn off Auto-Lock on your iOS device, you can do so by following these steps:

1) Launch the Settings app from the Home screen.

2) Open the Display & Brightness preferences pane.

3) Tap on the Auto-Lock cell.

4) Choose Never from the list of options.

When Never is chosen from the list, your device won’t lock itself automatically after any period of time; it doesn’t matter what you’re doing, whether you’re in an app, staring at your Home screen, or streaming via AirPlay. Keep in mind, however, that your Lock screen will still dim after a few seconds of inactivity as usual, no matter what Auto-Lock setting you choose.

Note: If you feel that your current Auto-Lock setting is too short and you don’t want to keep your device from Auto-Locking indefinitely, you can choose a prolonged time threshold instead.

Overall, the need to disable Auto-Lock comes down to a limited audience of people based on how the device is being used. Most iPhone users can benefit from Auto-Lock, so unless you’re a part of that limited pool, we recommend setting the feature to a designated time limit so you get the best battery life and device security.

    There definitely are times when someone would want to disable the auto autolock. And to make it a more convenient procedure, I recommend the Launcher app. Launcher is free (in-app paid upgrades available, of course) and allows you to place shortcuts in your Notification widgets panel. It supports many features in the Settings, as well as shortcuts to open apps, text or call contacts directly, create custom launchers and more. Of course, if you’re jailbroken, there are tweaks to enable direct control of autolock in the Control Center pull-up panel or you can use Activator to create a custom action such as tapping your status bar to turn it on and off.

    Great news, but what I’ve always hated is the lockscreen dimming so quick I don’t even get to see what ever I want to check out. Will apple ever wise up on this matter or maybe they don’t give a crap. Unless I have a jailbreak there’s no other way to do this.
