How to Disable Auto Lock on Any Device

Auto lock is one of those features that exists to protect you — but it can also get in the way. Whether your screen keeps going dark during a presentation, a recipe, or a long read, knowing how to disable or adjust auto lock gives you back control of your device. Here's how it works across the major platforms, and what you should think about before turning it off.

What Is Auto Lock and Why Does It Exist?

Auto lock (sometimes called screen timeout, sleep, or auto-sleep) is a system-level feature that automatically locks your screen after a set period of inactivity. It serves two core purposes:

• Security — preventing unauthorized access when you set your device down
• Battery conservation — turning off the display, which is typically one of the largest power drains on any device

Most operating systems enable auto lock by default and set it to somewhere between 30 seconds and 5 minutes. The exact label and location of the setting varies significantly depending on your platform.

How to Disable Auto Lock by Platform

iPhone and iPad (iOS / iPadOS)

On Apple mobile devices, auto lock is controlled through Settings:

1. Open Settings
2. Tap Display & Brightness
3. Tap Auto-Lock
4. Select Never

Note: If your iPhone is in Low Power Mode, the Auto-Lock option may be locked to 30 seconds and cannot be changed until Low Power Mode is disabled.

Android Devices

Android naming varies by manufacturer, but the general path is:

1. Open Settings
2. Go to Display (sometimes under Display & Brightness or Screen)
3. Tap Screen Timeout or Sleep
4. Select the longest available option — or Never, if your device offers it

⚠️ Not all Android manufacturers include a "Never" option. Samsung, Google Pixel, and OnePlus devices generally do, but some budget or carrier-locked devices cap the maximum timeout. If "Never" isn't available, the longest selectable timeout is your practical ceiling without third-party tools.

Windows PC

On Windows 10 and 11:

1. Open Settings
2. Go to System → Power & Sleep (Windows 10) or System → Power (Windows 11)
3. Under Screen, set "Turn off after" to Never
4. Under Sleep, set "PC goes to sleep after" to Never

You can also adjust lock behavior separately via Settings → Accounts → Sign-in Options, where you can set when Windows requires a password after sleep.

macOS

On a Mac:

1. Open System Settings (macOS Ventura and later) or System Preferences
2. Go to Lock Screen (Ventura+) or Security & Privacy → General
3. Adjust "Require password after sleep or screen saver begins" to a longer delay or turn it off
4. In Displays or Battery, set the display sleep timer to Never

Chromebook

1. Open Settings
2. Go to Device → Power
3. Under "When idle," set both the Sleep and Screen off options to Keep display on

The Security Trade-Off You Should Understand 🔒

Disabling auto lock isn't a neutral action from a security standpoint. It's one of the most basic access-control layers built into modern operating systems, and removing it has real implications depending on your environment:

In a home environment where you're the only user, disabling auto lock on a desktop or laptop carries relatively low risk. On a shared device, in a workplace, or on a mobile device you carry in public, a permanently unlocked screen is a meaningful vulnerability if the device is lost or left unattended even briefly.

Enterprise environments and managed devices often enforce auto-lock policies through MDM (Mobile Device Management) software, which can prevent end users from changing this setting at all.

When Disabling Auto Lock Actually Makes Sense

There are legitimate, common reasons to disable or extend auto lock:

• Using your device as a display — kiosks, digital photo frames, always-on dashboards
• Following along with instructions — cooking, DIY projects, reading long-form content
• Presentations or demos — especially when you're not actively interacting with the screen
• Accessibility needs — some users with motor impairments benefit from extended or disabled timeouts
• Development and testing — keeping a screen on is often necessary when building or debugging apps

In these cases, some users prefer to disable auto lock temporarily rather than permanently — adjusting the setting for a specific task and restoring it afterward.

Factors That Change Your Options

The degree of control you actually have over auto lock depends on several variables:

• Device ownership — company-managed or school-issued devices may restrict changes via policy
• Operating system version — older OS versions may have settings in different locations or with fewer options
• Manufacturer customization — Android in particular varies widely between brands
• Low Power Mode or Battery Saver — these modes on both iOS and Android can override or limit timeout settings
• User account type — standard (non-admin) accounts on Windows or macOS may not have permission to change power settings

Understanding which of these applies to your situation determines not just where to find the setting, but whether you can change it at all — and what alternatives exist if you can't.
