🔋 Know your user’s battery. Adapt your web app. Win the experience.
The modern web is all about context-aware performance — and battery level is one of the most overlooked signals.
This Device Battery Detector is a powerful little tool that uses the [Battery Status API] to detect:
🔋 Current battery level (in %)
🔌 Charging status (charging / not charging)
⏳ Battery discharging time (when supported)
⚡ Real-time status updates in the browser
Whether you’re building a PWA, an energy-efficient web game, or want to optimize your app behavior based on battery level (like disabling heavy animations, large downloads, or showing a “low battery mode”) — this utility is the perfect starting point.
✅ Uses native Battery-Manager API (no libraries)
✅ Clean HTML + JS code — plug-and-play
✅ Real-time updates with event listeners
✅ Fully browser-based — no backend needed
✅ Responsive UI — clear display of level & charging status
✅ Perfect for adding progressive enhancements to your app
