Description

🔋 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.


⚙️ Key Features

  • ✅ 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


🧠 Where This Tool Shines

  • 💻 Progressive Web App (PWA) optimization

  • 🎮 Game or media app battery-aware UX

  • 🚨 Triggering low battery warnings / lightweight mode

  • 👨‍🏫 Teaching environment variables, device APIs & browser capabilities

👨‍💻 Ideal For
