Caffeine: Prevent Lock Screen

Keep your display on and prevent your phone from locking!

Caffeine: Prevent Lock Screen is the ultimate lightweight screen keep-awake utility designed to stop your screen from turning off, dimming, or locking unexpectedly. Whether you are reading long articles, following recipes in the kitchen, monitoring real-time servers, reviewing presentations, or downloading large files, Caffeine Mode ensures your screen stays illuminated exactly as long as you need.

🛡️ RUNS RELIABLY WHEN MINIMIZED & SWIPED AWAY

Unlike standard tools that pause when you switch tasks, Caffeine is built for true background resilience:

• Works System-Wide in Background: Minimizing the app or using other full-screen apps will not interrupt your keep-awake session.

• Survives Killed Sessions & App Switcher Swipes: Even if the app is swiped away from recent tasks or killed by Android memory management, our intelligent session recovery engine automatically restores your countdown and keeps the display awake without missing a beat.

☕ WHAT IS CAFFEINE MODE?

Like drinking a fresh cup of coffee, Caffeine Mode gives your Android screen a boost, keeping the display awake and preventing lock screen timeouts without permanently altering your system display settings. Once your task is finished, your normal display sleep timer automatically resumes.

🚀 KEY FEATURES:

• One-Tap Caffeine Toggle: Prevent lock screen with a single touch from the main dashboard.

• Minimized & Background Persistent: Works continuously across all other apps and recovers cleanly even if closed from recent task sessions.

• Quick Settings Tile: Toggle Caffeine Mode directly from your Android notification drop-down without opening the app.

• Flexible Timer Presets: Keep screen awake for 1 minute, 5 minutes, 15 minutes, 30 minutes, 1 hour, 2 hours, 3 hours, or infinite duration.

• Screen Dimming Protection: Stops unwanted screen timeout during gaming, reading, coding, or navigating.

• Low Battery Guardian: Optional auto-stop when battery level drops below your threshold.

• Floating Timer Pill: Optional compact floating countdown indicator visible while using other apps.

• AMOLED Dark Theme: Clean, modern interface designed to minimize battery consumption.

• Notification Control: Check remaining keep-awake time and turn off Caffeine Mode right from your lock screen or status bar.

• 100% Privacy Focused & Ad-Free: Zero advertisements, zero trackers, and no root permissions required.

🎯 PERFECT FOR:

- Reading eBooks, PDF manuals, and tutorials without touching the screen every 30 seconds.

🔒 PRIVACY & PERMISSIONS:

Prevent LockScreen requires minimal permissions to function:

- Foreground Service & Wake Lock: Essential to maintain the keep-awake state reliably in the background without Android terminating the service.
