Auto Lock on your iPhone is a feature that can either be a lifesaver or a constant annoyance, depending on how you use your device.

Whether you’re an avid reader, a busy professional, or someone who just enjoys a longer display time, setting the Auto Lock to a time that suits your usage can greatly enhance your iPhone experience. Consider this: you’re in the middle of reading an exciting article or recipe, and suddenly your screen goes black.

Annoying, right? Adjusting the Auto Lock setting can prevent this from happening. Plus, it’s a setting that can help save your battery life when you’re not actively using your phone. This article will take you through a step-by-step guide to adjust your iPhone’s Auto Lock setting, discuss the pros and cons of changing this setting, and offer some additional tips to get the most out of your iPhone.

Step by Step Tutorial to Adjust iPhone Auto Lock

Before you begin, please note that you can only change the Auto Lock setting when your iPhone is not in Low Power Mode.

Step 1: Open the Settings app

Open the Settings app on your iPhone.

The Settings app is your control center for all things iPhone. It’s where you can tweak and customize your device to fit exactly how you use it.

Step 2: Tap on ‘Display & Brightness’

Scroll down and tap on ‘Display & Brightness’ in the Settings menu.

‘Display & Brightness’ is where you can adjust screen-related settings, such as brightness, text size, and, of course, the Auto Lock timing.

Step 3: Tap on ‘Auto Lock’

Within the ‘Display & Brightness’ settings, you’ll find the ‘Auto Lock’ option. Tap on it to see the time options available.

Here you can choose the duration before your iPhone goes into lock mode. The times range from 30 seconds to 5 minutes, or ‘Never’ if you don’t want it to auto-lock at all.

Step 4: Select your preferred time interval

Tap on the interval you prefer for your iPhone’s Auto Lock setting.

Once you tap on a time interval, your iPhone will automatically save this setting. You can change it anytime by repeating these steps.


Extended Screen TimeChoosing a longer Auto Lock time means you can use your iPhone without the constant interruption of unlocking your screen. This is particularly handy if you’re following a recipe or reading an article.
Battery ConservationBy setting a shorter time, you can save battery life because the screen isn’t on as long. This is useful when you know you won’t be using your phone much.
SecurityA shorter Auto Lock time can increase security, as it reduces the window of opportunity for unauthorized access if you happen to leave your phone unattended.


Battery DrainIf you set the Auto Lock to ‘Never’ or a long interval, it can drain your battery more quickly because the screen stays active longer.
Security RiskA longer Auto Lock time can pose a security risk if your phone is lost or stolen, as it gives more time for someone to access your device.
InconvenienceIf set too short, it might be annoying to frequently unlock your phone, especially if you’re in the middle of using an app or reading.

Additional Information

Adjusting your iPhone’s Auto Lock setting is just one way to customize your experience, but it’s important to consider how it fits into your overall phone usage. If you’re someone who often puts their phone down and forgets to lock it, a shorter Auto Lock time can be a good security measure.

But if you’re using your phone for work or reading, a longer time might be more convenient. Remember, the ‘Never’ option should be used with caution, as it means your phone will stay on until you manually lock it, which can be a significant drain on your battery and a security risk.


  1. Open the Settings app.
  2. Tap on ‘Display & Brightness’.
  3. Tap on ‘Auto Lock’.
  4. Select your preferred time interval.
