There are many reasons why you might want to prevent your iPhone from going to sleep. You could be reading a document, creating digital art, editing a photo, and more. In all of these cases, it can be a great idea to keep your iPhone awake while you think about your creation or text. But by default, your iPhone is set to go to sleep after one minute on your iPhone.

You may also experience issues with features like automatically dimming your screen brightness or automatically going to sleep. Whatever the reason, here's how to disable these features and prevent your iPhone from going to sleep.

Your iPhone will automatically go to sleep after a while due to its Auto Lock settings, which are set to 1 minute by default. This means that your iPhone will automatically go to sleep after being inactive for 1 minute. This feature is primarily designed to extend your device’s battery life by reducing battery consumption by putting active apps to sleep, turning off the screen, and occasionally waking up essential services to receive push notifications, and more. Additionally, your iPhone will employ other features to reduce your device’s battery consumption in real-time without impacting performance.

This includes Auto-Brightness, a feature that uses your device’s light sensor to measure ambient light and adjust your screen brightness accordingly. However, when this feature is buggy or incorrectly measures ambient light due to multiple sources and motion, it can cause your screen brightness to vary incorrectly, causing it to dim in situations when it shouldn’t.
