Battery Health Monitor

🔋 Battery Health Monitor shows you what's actually happening inside your phone's battery, all in one clean, easy-to-read dashboard. No guesswork, no clutter, no confusing menus. Just real numbers from your device, updated live, so you can understand how your battery behaves and how to make it last. Curious why your phone drains so fast, or whether your charger is doing its job? Get the full picture at a glance. ✨ WHAT YOU GET 📊 Live Dashboard Your battery level and temperature appear as simple, at-a-glance gauges. The colors shift as conditions change, so you can tell in a second whether everything is fine or needs attention. ⚡ Real-Time Readings Watch voltage, current, and power update live while you use your phone or while it charges. See exactly how much power your charger delivers and how hard your device is working. 🔌 Charging Status Know whether you're charging, discharging, or fully charged, along with the plug type: AC, USB, or wireless. 📈 Trends You Can Actually Use Explore level and temperature charts over 2 hours, 24 hours, 7 days, or up to 14 days. Spot patterns like overnight drain, heat spikes while gaming, or slow charging sessions. 🕒 Charge & Discharge Timeline A running log of events: when charging started, when you unplugged, when the battery reached full, and when it ran hot. High-temperature events are flagged so nothing slips by. 🔁 Charging Habit Insights See your averages at a glance: charge cycle count, average charging speed, and the typical percentage where you start and stop charging. Small habit changes, like unplugging earlier, can help your battery age more gracefully. 📱 Screen-On Time by Day Track how long your screen stays on each day and see how it lines up with your battery use. 🔔 Optional Alerts Set a charging-limit notification (for example, at 80%) so you remember to unplug before the battery sits at 100%. Turn on high-temperature alerts to get warned when your device runs hot. Both are off by default and entirely up to you. 🌗 Light, Dark, or System Theme A clean design that looks great day or night, and follows your phone's theme if you prefer. 💡 WHY PEOPLE LIKE IT - Simple. The important numbers are front and center, with no jargon. - Honest. It shows measured values from your device instead of invented scores or "health percentages" that Android doesn't reliably provide. - Private. Everything stays on your device. 🔒 PERMISSIONS & PRIVACY Battery Health Monitor reads battery and screen state through standard Android system broadcasts, which need no special permission. The only permission it ever asks for is notifications (Android 13 and above), and only if you turn on the charging-limit or high-temperature alert. It is never required to use the app. The app does not collect your personal data, and your battery history is stored only on your device. Ads are shown by Google AdMob, which may use standard device identifiers to serve and measure ads, as described in Google's policies and our privacy policy. 🎁 ADS The app is free and supported by ads.

Some readings, such as current and power, depend on your hardware. Timeline and trend data build up while the app is running, so open it regularly for the best history. 🙋 QUESTIONS OR FEEDBACK?
