Battery Monitor & Tracker

Free · In‑App Purchases

Real-time drain tracking, smart predictions, burst monitoring & intelligent insights. Your battery's personal guardian — always watching. YOUR BATTERY DESERVES THE BEST PROTECTION. BELIEVE ME. Nobody — and I mean nobody — knows your iPhone battery better than Battery Guardian. It's smart, it's beautiful, it's tremendous. And it's going to keep you charged. THE PROBLEM NOBODY IS SOLVING You look down at your phone: 18%. How did that happen? You were at 60% an hour ago. Where did it go? Your iPhone shows you a number — Battery Guardian shows you the story behind that number. Big difference. Huge. REAL-TIME DRAIN MONITORING See exactly how fast your battery is draining — right now, in percent per hour. Not a vague estimate. Not a guess. The actual rate, live, updating every 30 seconds. When something starts eating your battery, you'll know immediately. TIME REMAINING — ALWAYS INFORMED Know exactly how much time you have left, calculated from your real drain rate — not a generic factory estimate. Planning a long meeting? A flight? A road trip? Battery Guardian tells you if you're going to make it. FULL BATTERY HISTORY Your battery's complete story, going back up to 90 days. See how it performed yesterday, last week, last month. Tap any point on the chart to see exactly what was happening. This is the data Apple doesn't show you. INTELLIGENT INSIGHTS — THIS IS WHERE IT GETS GOOD Battery Guardian analyzes your usage patterns and serves up smart insights: Depletion forecast: "You'll hit 20% at 6:45 PM" — plan accordingly Peak drain window: "Your battery drains hardest between 8–10 AM" — find out why Weekly trend: "Draining 18% faster than last week" — something changed Charging habit analysis: "You typically charge at 11 PM at 24%" — is that healthy? Low-battery streak: Days without hitting the danger zone — keep the streak alive SMART NOTIFICATIONS Get an instant alert the moment you plug in or unplug your charger. Know when you're approaching your personal low-battery threshold — set it at 10%, 20%, 30%, wherever you need the warning. Never get caught off guard again. BURST MODE When you need ultra-precise monitoring — like during an intense work session or while troubleshooting unusual drain — activate Burst Mode with a long press on the gauge. Samples every 5 seconds for 2 minutes. The detail is extraordinary. GORGEOUS, NATIVE DESIGN Built entirely in SwiftUI for iOS 17. Each stat card glows with its own accent color. Every detail view opens with a background that matches the card you tapped. Light mode, dark mode, and Auto - your choice, your style. WHO NEEDS BATTERY GUARDIAN? - Anyone who has ever been stranded at 0% at the worst possible moment - Power users who want to understand their device deeply - Travellers and commuters who need to plan around battery life - Anyone who suspects an app is secretly killing their battery - People who want to protect their battery's long-term health THE BOTTOM LINE The standard iOS battery indicator shows you a number. Battery Guardian shows you intelligence. Pattern analysis. Predictions. Trends. Alerts. History. Real data, beautifully presented, always accurate. This is not just a battery app. This is a Battery Guardian. Download it. Your battery will thank you.
