How to keep your iPhone screen on
😴 Change Auto-Lock, or use the tool below ⏰
Your iPhone locks the screen after a short time to save battery. To keep it on you can raise (or remove) the Auto-Lock timer, or use the no-install tool below while you're in Safari.
Change the Auto-Lock timer
This keeps the screen on across every app, not just the browser.
- Open Settings.
- Tap Display & Brightness.
- Tap Auto-Lock.
- Choose a longer time, or Never to keep the screen on until you lock it yourself.
Never is greyed out while Low Power Mode is on — turn it off first under Settings › Battery. Remember to set Auto-Lock back afterwards, since a screen that never sleeps drains the battery fast.
Use this free browser tool
Only need the screen on inside Safari — reading a page, showing a QR code, or using the screen as a light? The button below keeps it on without touching Auto-Lock.
Only works while this tab stays open and visible — not minimized, and not switched away to another tab.
Free & ad-free — buy me a coffeeWorks in Safari on iOS 16.4 and later. It keeps the screen on only while this Safari tab is the one on screen — switch to another app and the screen can lock again. For keeping other apps on, use the Auto-Lock setting above.
Which one should you use?
Change Auto-Lock when you need the screen on in any app — navigation, or cooking with a recipe app. Use the tool for a quick option on a webpage that resets itself, so you never forget to change it back.
FAQ
Why is the Never option greyed out?
Low Power Mode forces a short Auto-Lock. Turn it off under Settings > Battery and the Never option becomes available again.
Does keeping the screen on drain the battery?
Yes — the display is the single biggest battery user. Set Auto-Lock back to 30 seconds or 1 minute once you're done.
