Where to find the screen timeout setting on your iPhone

Your iPhone's screen timeout — the time it waits before turning the display off — lives in Settings under Display & Brightness. Open Settings, tap Display & Brightness, then look for Auto-Lock. That's the setting that controls how long your screen stays on when you're not using it.

The Auto-Lock menu shows you five preset options: 30 seconds, 1 minute, 2 minutes, 5 minutes, and 10 minutes. You can also choose Never, which keeps your screen on indefinitely until you manually lock it. Tap whichever option matches what you want, and the change takes effect when ready.

Key Takeaways

  • Auto-Lock is found in Settings > Display & Brightness and controls how long your screen stays on before turning off automatically.
  • Your choices are 30 seconds, 1 minute, 2 minutes, 5 minutes, 10 minutes, or Never.
  • Shorter timeouts (30 seconds to 1 minute) save battery life but require more frequent unlocking.
  • The Never setting keeps your screen on until you manually lock it, which drains the battery quickly.
  • Your choice applies to your entire phone unless you disable Auto-Lock in specific apps or situations.

Why you might want to change your timeout

A shorter timeout saves battery life because your screen consumes far more power than any other part of your phone. If you're away from a charger for most of the day, dropping from 5 minutes to 1 minute can add an hour or more of usage time. The trade-off is that you'll unlock your phone more often when you're actively using it.

A longer timeout is useful if you're reading, following a recipe, or referencing something on your screen for extended periods. You won't have to keep unlocking. However, if you set it to Never, your battery will drain noticeably faster, especially if you accidentally leave your phone on a table with the screen lit.

What happens when Auto-Lock turns your screen off

When the timer runs out, your screen goes black and locks. Any app you were using pauses where it was. When you unlock your phone again, most apps return to the same place you left them — though some apps (like music or video) may have stopped playing.

Auto-Lock does not close your apps or delete anything. It straightforward locks the screen to prevent accidental touches and save power. Your phone continues running in the background: notifications still arrive, calls still ring, and timers keep counting.

How to keep your screen on in specific situations

If you want your screen to stay on longer for one task but keep the normal timeout for everything else, you have two options. First, you can temporarily change Auto-Lock to a longer time, complete your task, then change it back. This takes 20 seconds but works reliably.

Second, some apps have their own screen-on settings. For example, Apple Maps, the Stocks app, and many recipe apps let you disable Auto-Lock just while they're open. Look in the app's settings menu — usually found by tapping a gear icon or three horizontal lines — for an option like "Keep Screen On" or "Disable Auto-Lock."

Common mistakes when adjusting Auto-Lock

The most common mistake is setting Auto-Lock to Never and forgetting about it. Your battery will drain 20 to 30 percent faster than normal because the screen stays lit even when you're not using your phone. If you choose Never, set a reminder to change it back within a day or two.

Another mistake is setting the timeout too short if you use your phone for reading or reference. A 30-second timeout means your screen locks while you're still looking at it, which is frustrating. If you read a lot, try 2 or 5 minutes instead and accept the small battery cost.

How Auto-Lock interacts with Face ID and Touch ID

Auto-Lock and Face ID or Touch ID work together. When your screen locks due to Auto-Lock, you unlock it again using Face ID (by looking at your phone) or Touch ID (by pressing your fingerprint sensor). The timeout doesn't change how you unlock — it only controls when the lock happens.

If you have a very long Auto-Lock time and someone else picks up your phone, they can see your screen without unlocking it. For security, keep Auto-Lock at 2 minutes or less if your phone contains sensitive information or if you're in a shared space.

Frequently Asked Questions

Does Auto-Lock drain my battery even when I'm not using my phone?

No. Auto-Lock only matters when your screen is on. If your phone is in your pocket or on a table with the screen already off, the Auto-Lock setting has no effect. Battery drain from Auto-Lock happens only when you leave your screen on and then walk away without locking it manually.

Can I set different Auto-Lock times for different situations?

Not automatically. You can only have one Auto-Lock setting for your whole phone. If you need different timeouts for different tasks, you'll need to change the setting manually each time. Some third-party apps offer automation shortcuts that change Auto-Lock based on location or time of day, but these require setup in the Shortcuts app.

What's the best Auto-Lock time for battery life?

Thirty seconds to 1 minute gives you the best battery savings. Two minutes is a good middle ground if you find 30 seconds too annoying. Anything longer than 5 minutes uses noticeably more power, especially if you set it to Never.

Will my apps close if my screen locks due to Auto-Lock?

No. Your apps stay open and running in the background. When you unlock your phone, they return to where you left them. The only exception is apps that require active interaction — for example, a video stops playing, but you can resume it from where it paused.

Can I turn off Auto-Lock completely?

Yes, by choosing Never in the Auto-Lock menu. However, this drains your battery much faster and leaves your phone vulnerable if you set it down without locking it manually. Most people should avoid this unless they have a specific reason to keep their screen on all the time.
