Does it work on iPad too?

Yes. It works the same way on iPadOS in Safari or Chrome. Keep the browser tab open and on screen.

Which iOS version do I need?

iOS and iPadOS 16.4 or later support the Screen Wake Lock API in Safari. On older versions the tool uses a fallback method, though keeping the screen fully awake is most reliable on 16.4+.

Why does the screen still dim when I lock the phone or switch apps?

The wake lock only works while the browser tab is open and visible. If you switch to another app or lock the phone, iOS releases it. Return to the tab and it re-activates automatically.

How do I keep the screen on inside another app or a game?

No web page can control other apps. For that, use Apple's Guided Access: Settings > Accessibility > Guided Access, then triple-click the side button inside the app. For content in Safari or Chrome, ScreenWakeUp does it with one tap and no setup.

How to keep your iPhone screen awake

Q: How do I keep my iPhone screen on without changing Auto-Lock?

Open screenwakeup.com in Safari and tap 'Keep Screen Awake'. It uses the Screen Wake Lock API (iOS 16.4+) to hold the screen on while the tab is open, so you don't have to change Settings > Display & Brightness > Auto-Lock.

Q: How do I keep my iPhone screen on?

Open screenwakeup.com in Safari, pick a duration and tap Keep Screen Awake. The screen stays on until you stop it or close the tab — no app and no Settings changes, and normal Auto-Lock resumes when you're done.

Q: How do I stop my iPhone screen from turning off?

There are two routes. The system one: Settings > Display & Brightness > Auto-Lock, then pick a long duration or Never (remember to undo it, since it leaves the phone unlocked). The quick, temporary one: open screenwakeup.com in Safari and tap Keep Screen Awake — the screen stays on while the tab is open and visible, and your normal Auto-Lock returns as soon as you close it.

Q: Why is Auto-Lock greyed out on my iPhone?

Almost always Low Power Mode: while it is on, iOS pins Auto-Lock to 30 seconds and disables the setting. Turn it off in Settings > Battery. If it is still greyed out, it is usually a configuration or MDM profile from work or school, under Settings > General > VPN & Device Management.

Stop your iPhone or iPad screen from turning off — without changing Auto-Lock and without installing any app. It runs right in Safari, free.

Reading a recipe, following sheet music, scanning a QR menu, or watching a doc on your phone? iOS dims and locks the screen after your Auto-Lock timeout. You could dig into Settings every time — or just open ScreenWakeUp, which uses the Screen Wake Lock API (iOS 16.4+) to hold the screen on while the tab is open.

Quick version: open screenwakeup.com in Safari → tap Keep Screen Awake → keep the tab visible. Done.

Keep your iPhone screen on in 3 steps

Open screenwakeup.com in Safari on your iPhone or iPad.
Choose a duration — 30 min, 1h, 2h, 4h, or ∞.
Tap Keep Screen Awake and keep the Safari tab open and on screen.

Tip: add it to your Home Screen (Share → Add to Home Screen) so it opens like an app.

How to change iPhone Auto-Lock, step by step

If you'd rather change the system setting itself, here is the exact path:

Open Settings.
Go to Display & Brightness.
Tap Auto-Lock.
Pick 30 seconds, 1, 2, 3, 4 or 5 minutes — or Never.

It works, but it has a price: with Never, your screen stops locking altogether, the battery drains faster, the phone sits unlocked all day, and you have to remember to undo it. That is exactly why this page exists — ScreenWakeUp keeps the screen on only while you need it, and the moment you close the tab your usual Auto-Lock is back, with nothing to change and nothing to undo.

Is Auto-Lock greyed out?

If the option is dimmed and won't respond, it is almost always Low Power Mode: while it's on, iOS pins Auto-Lock to 30 seconds and locks the setting. Turn it off in Settings > Battery and you can change it again (it also switches itself off once you charge above 80%). If it stays greyed out, it's usually a configuration or MDM profile from work or school — check Settings > General > VPN & Device Management; that one is your organisation's call, and no trick gets around it.

Honest warning: with Low Power Mode on, the browser can also release the screen wake lock this page relies on. That's an iOS restriction, not a bug on our side — if the screen still goes dark, check your battery settings first.

What you need

iOS / iPadOS 16.4 or later for the native Wake Lock API in Safari.
The browser tab must stay open and visible — if you switch apps or lock the phone, iOS releases the lock and re-acquires it when you return.

Inside apps and games? Use Guided Access

Honest answer: a web page can only keep the screen on while you're looking at it in the browser. If you need the screen always on inside another app or a game, use Apple's built-in feature: Settings > Accessibility > Guided Access, turn it on, then triple-click the side button inside the app. For anything that happens in Safari or Chrome — recipes, guides, maps, documents — ScreenWakeUp is faster: one tap, nothing to set up.

How do I keep my iPhone screen on?

Open screenwakeup.com in Safari, pick a duration (or ∞) and tap Keep Screen Awake. The screen stays on until you stop it or close the tab — no app, no digging through Settings, and Auto-Lock goes back to normal the moment you're done.

Does it work on iPad?

Yes, identically — Safari or Chrome on iPadOS. Great for recipes, presentations and kiosk-style displays.

Will it drain my battery?

Keeping any screen on uses power, but only while the tab is active. Close it and normal Auto-Lock resumes immediately, so it's far safer than setting Auto-Lock to Never.
