How to Stop iPhone from Sleeping [2023]

There may be many reasons why you might want to prevent your iPhone from going to sleep. You might be reading documents, creating digital art, editing photos, and more. In all of these cases, it might be a good idea to keep your iPhone active while you think about and review your creations or texts. But by default, your iPhone is set to go to sleep after one minute on your iPhone.

You may also encounter issues with features such as the screen brightness automatically dimming or sleep focus mode automatically turning on. Whatever the reason, here's how to disable these features and prevent your iPhone from going to sleep.

Why does your iPhone go to sleep after a while?

Due to its auto-lock setting, your iPhone automatically goes to sleep after a certain amount of time, which is set to 1 minute by default. This means that after your iPhone is idle for one minute, it will automatically go to sleep. This feature is primarily designed to extend the battery life of your device by reducing battery consumption by putting active apps to sleep, turning off the display, and occasionally waking up essential services to receive push notifications. In addition to this, your iPhone also deploys other features to reduce the battery consumption of the device in real time without affecting its performance.

This includes the Auto-Brightness feature, which uses the device's light sensor to measure ambient light and adjust screen brightness accordingly. However, when this feature faces a bug or incorrectly measures ambient light due to multiple sources and movement, your screen brightness may change incorrectly, causing it to dim when it shouldn't.

So whether it’s preventing your iPhone from automatically locking or your iPhone screen randomly dimming, you can use the step-by-step guide below to fix these issues.

How to Keep iPhone from Sleeping

Here’s how to prevent iPhone from sleeping based on the behavior you want to change. Please follow the relevant sections below to help you through the process.

1. Prevent iPhone from locking

To prevent iPhone from locking and automatically going to sleep, you can change the Auto-Lock setting. Here's how to do it on your iPhone.

Open the Settings app on your iPhone and tap "Display & Brightness".

Click Automatically lock.

Now click and select Never.

That's it! After selecting "Never", your iPhone will never automatically lock. This means your screen will remain on indefinitely unless you decide to manually lock the device by pressing the Sleep/Wake button. We recommend that you manually lock your device when not working if possible, as this will help you conserve battery power and extend the life of your iPhone on its current charge.

2. Prevent the screen from dimming

You may also want to prevent the screen from automatically dimming due to automatic brightness adjustment. Here's how to disable it on your iPhone.

Open the "Settings" app and click "Accessibility".

Click Display and text size.

Scroll to the bottom and turn off Auto-Brightness.

That's it! Your iPhone will no longer automatically manage the brightness of the display, which will prevent it from randomly dimming. However, we recommend that you manually turn up the brightness on your iPhone whenever possible to save battery power.

3. Prevent iPhone from automatically turning on sleep focus mode

Do you also want to prevent iPhone from automatically turning on sleep focus mode every day? This can happen if you have Sleep Scheduler turned on in the Health app. Disabling this feature will prevent your iPhone from automatically activating Sleep Focus Mode. Follow the steps below to help you turn off this feature on your iPhone.

Open the "Health" app and click "Browse" at the bottom.

Now click Sleep.

Scroll down and click "Full schedule and options".

Click and turn off the "Sleep Plan" switch at the top of the screen.

That's it! Your iPhone will no longer automatically turn on Sleep Focus Mode on a set schedule. Every time you use sleep focus mode, you have to activate it manually.
