Galaxy S10 Keep Screen On Longer: Settings Guide

Updated 5 November 2026 · Standard formula, shown below

To keep your Galaxy S10 screen on longer, go to Settings > Display > Screen timeout and choose a longer duration, up to 10 minutes. This article explains the exact steps, related settings like Smart Stay, and common issues that prevent the timeout from working as expected.

Understanding Screen Timeout on the Galaxy S10

The screen timeout (also called sleep timer) controls how long the display stays on after your last touch. When the timer expires, the phone locks itself to save battery and prevent accidental input. On the Galaxy S10, the default is usually 30 seconds, but you can extend it to 1, 2, 5, or 10 minutes. The maximum is 10 minutes; Samsung does not offer an “always on” option in the stock settings for this model.

Why does this matter? A longer timeout is useful when you’re reading a recipe, following directions, or using the phone as a reference while your hands are busy. However, a longer timeout drains the battery faster and can cause screen burn-in on the AMOLED display if a static image is left on for long periods. Finding the right balance is key.

Step-by-Step: How to Change the Screen Timeout

Unlock your Galaxy S10 and open the Settings app (the gear icon).
Scroll down and tap Display.
Tap Screen timeout.
Select your preferred duration: 15 seconds, 30 seconds, 1 minute, 2 minutes, 5 minutes, or 10 minutes.
Exit settings; the change takes effect immediately.

That’s all there is to it. If you want the screen to stay on only while you’re looking at it, use the Smart Stay feature described next.

Smart Stay: Keep Screen On While You Look

Smart Stay is a Samsung feature that uses the front camera to detect if you’re looking at the screen. When enabled, the screen won’t time out as long as it detects your eyes. This is a great alternative to setting a long timeout, because it automatically turns off when you look away, saving battery.

To enable Smart Stay on the Galaxy S10:

Open Settings.
Tap Advanced features.
Tap Motions and gestures.
Toggle Smart Stay to on.

Note that Smart Stay works best in good lighting. In dim conditions, the camera may not detect your eyes reliably, and the screen may still turn off. Also, it only works when you’re facing the phone; if you’re reading while the phone lies flat on a table, it might not work.

Why Won’t My Screen Stay On? Common Problems

If you set a longer timeout but the screen still turns off quickly, several factors could be at play:

Power saving mode: Battery saver modes often force a shorter timeout. Check Settings > Device care > Battery > Power mode and switch to Optimized or High performance.
Smart Stay is off: If you expect the screen to stay on while you look at it, make sure Smart Stay is enabled.
Apps with their own timeout: Some apps, like video players or navigation apps, override the system timeout. For example, Google Maps has a separate “Keep screen on” setting in its own menu.
Screen timeout is set per profile: If you use multiple user profiles or a work profile, each may have its own timeout setting.
Hardware issue: Rarely, a faulty proximity sensor or camera can cause the screen to turn off prematurely. If the problem persists, test with Safe Mode.

How to Keep Screen On in Specific Apps

Sometimes you don’t want a global longer timeout; you just need one app to stay awake. Many apps have a built-in “keep screen on” option. For example:

YouTube: The screen stays on during video playback by default.
Chrome: You can use the flag #keep-screen-on but it’s not recommended for general use.
Google Maps: In navigation mode, the screen stays on automatically.
Third-party apps: Apps like “Stay Awake” or “Screen On” can force the screen on for selected apps, but they require extra permissions and may not work on all Android versions.

If an app doesn’t have its own setting, you can use the developer option “Stay awake” which keeps the screen on while charging. This is useful for long tasks while plugged in.

Battery Life and Screen Burn-In Concerns

Setting a longer timeout will increase battery consumption. The display is one of the biggest power drains on a smartphone. A 10-minute timeout could reduce battery life by 20-30% compared to a 30-second timeout, depending on usage. If you often forget to lock the phone, the screen will stay on longer, wasting power.

Screen burn-in is another concern. The Galaxy S10 uses an AMOLED display. Leaving a static image (like a clock or a navigation bar) on for hours can cause permanent ghosting. Samsung has built-in protections like moving the clock slightly, but they are not foolproof. For this reason, avoid using the maximum timeout for static content for extended periods.

Alternatives to a Longer Screen Timeout

If you need the screen on for tasks but want to save battery, consider these alternatives:

Smart Stay: As described above, it keeps the screen on only while you look at it.
Always On Display: This shows the clock and notifications without fully lighting the screen. It uses very little battery and doesn’t cause burn-in because it moves around.
Use a physical book stand: If you’re reading a recipe, prop the phone up and use Smart Stay.
Set a shorter timeout and tap the screen: It’s a simple habit that saves battery.

Frequently Asked Questions

Can I set the screen timeout to more than 10 minutes? No, the stock Galaxy S10 settings only allow up to 10 minutes. To go beyond, you’d need a third-party app that sends a wake lock, but that can drain battery and may not be reliable.

Why is my screen timeout greyed out? This usually happens when a power saving mode is active. Turn off battery saver in Settings > Device care > Battery > Power mode.

Does Smart Stay work with sunglasses? It may not, because the camera needs to see your eyes. Remove sunglasses or use a longer timeout instead.

Will a longer screen timeout cause burn-in? Yes, if you leave a static image on for many hours. The risk increases with brightness. Use a shorter timeout for static content.

How do I set a different timeout for specific apps? There’s no built-in per-app timeout on the Galaxy S10. You can use Bixby Routines to set a condition (e.g., when a specific app is open, set timeout to 10 minutes) but this requires setup in the Bixby Routines app.

What is the default screen timeout on the Galaxy S10? It varies by carrier and software version, but it’s usually 30 seconds. You can change it as described above.
