How to Change Your iPhone’s Sleep Mode Settings for Better Battery Life

Changing your iPhone’s sleep mode is a quick and easy process that involves a few taps within the settings app. After completing the action, your iPhone will either go to sleep faster or stay awake for longer periods, depending on your preferences.

After changing the sleep mode settings, your iPhone will follow the new timing for auto-locking the screen. This can help save battery life or prevent the screen from turning off too quickly while you’re using it.


We’ve all been there – you’re reading an article or playing a game on your iPhone, and suddenly, the screen goes black. It’s the sleep mode kicking in, and sometimes it can be quite a nuisance, especially if it happens too quickly. But did you know you can actually control when your iPhone decides to take a quick nap?

Sleep mode on an iPhone is an essential feature that conserves battery life and enhances security. It’s the function that turns off your device’s screen after a period of inactivity. For some users, the default setting might be just right, but for others, it could be too short or too long. Whether you’re a power user who needs their phone on at all times, or you’re looking to conserve as much battery life as possible, adjusting this setting can make a significant difference in how you use your phone.

In this article, we’ll be diving into the simple steps of how you can take control of your iPhone’s sleep mode settings. This guide is for anyone who wants to customize their device to better fit their lifestyle and usage habits.

Step by Step Tutorial – Changing Your iPhone’s Sleep Mode

Before we dive into the steps, it’s essential to know that adjusting your iPhone’s sleep mode settings directly affects the auto-lock feature. Auto-lock refers to the amount of time your iPhone waits before turning off the display after you stop touching the screen.

Step 1: Open the Settings app

Access the settings on your iPhone by tapping the gear icon on your home screen.

The Settings app is where you can tweak almost every aspect of your iPhone’s system preferences, including display and brightness, which is where the sleep mode settings are housed.

Step 2: Scroll down and tap on “Display & Brightness”

This section controls the visual aspects of your iPhone, including screen brightness, text size, and, crucially, the auto-lock timeout.

Within “Display & Brightness,” you’ll find various options for adjusting how your iPhone’s screen behaves. It’s the gateway to tailoring your iPhone’s visual experience to your liking.

Step 3: Tap on “Auto-Lock”

Selecting this option will allow you to change when your iPhone goes to sleep.

The Auto-Lock feature is designed to give you a range of time intervals to choose from. This ensures you can select a timing that works best for your usage pattern.

Step 4: Choose your preferred time

Select the time interval you want your iPhone to wait before going to sleep.

The available times range from 30 seconds to 5 minutes, or you can choose to never auto-lock. Consider how you use your iPhone and what interval will be most convenient for you.


Longer Battery LifeSetting a shorter time for auto-lock can help conserve your iPhone’s battery life. When the screen is off, it’s not consuming power, so the faster your phone sleeps, the more battery you save.
Increased SecurityWith a shorter auto-lock time, your iPhone will require authentication sooner, which can protect your data if your phone is lost or stolen.
Prevents Unintentional TouchesIf you tend to put your iPhone down without locking it, a shorter auto-lock time can prevent accidental touches or calls.


InconvenienceA shorter auto-lock time may require you to unlock your device more frequently, which can be annoying if you’re using your phone intermittently.
May Interfere with Certain AppsSome apps or activities may not function well with a shorter auto-lock time, such as GPS navigation or reading long articles.
Can Be DistractingIf you set the auto-lock time too short, the frequent screen dimming and locking can interrupt your flow, especially if you’re in the middle of something important.

Additional Information

It’s worth noting that the “Never” option, which prevents your iPhone from automatically going to sleep, should be used with caution. While it may seem convenient, it can significantly drain your battery and leave your device vulnerable if left unattended. Also, remember that your auto-lock settings won’t affect your iPhone’s ability to lock manually; you can always press the power button to lock your screen instantly.

Another tip is to make use of the “Raise to Wake” feature. This feature automatically wakes your iPhone’s screen when you pick it up, making it easier and faster to get back to what you were doing. It’s a great complement to any auto-lock setting you choose.

Lastly, if you’re keen on saving battery life but don’t want a short auto-lock time, consider adjusting your screen’s brightness or enabling Low Power Mode. Both can help extend your battery life without the need to frequently unlock your device.
