Battery Health & Analyzer

Never miss a full charge. Never wake up to a dead phone. Battery Health & Analyzer watches your battery in the background and sounds an alarm when it is full, low, unplugged, or running hot — even when the screen is locked. Stop overnight overcharging. Catch overheating early. See live level, temperature, voltage, current, and charging power on one dashboard. Smart charging alarms • Full battery alert — set the percentage and unplug on time • Low battery alert — get a warning before the phone dies • Plug in / plug out alerts — know when charging starts or stops • Overheat alert — notified when temperature crosses your limit • Sound, vibration, snooze, and repeat until you stop it • Optional alarm even in Silent / Do Not Disturb Live battery dashboard • Charge level, status, and charger type • Temperature, voltage, current, and calculated charging power • Charging speed class and estimated time to full or empty • Battery health as Android reports it — we never invent a fake health score • Metrics your phone does not expose stay Unavailable, not guessed Charging history, on this device • Session duration, max temperature, and max power • Battery level over time • Today, 7-day, and 30-day stats • Stored locally. No account. Core features work offline. Power tools • Brightness, screen timeout, auto-rotate, and ring mode shortcuts • Charging screen when a charger is connected • Optional floating temperature bubble over other apps • Light, dark, and AMOLED themes • Multiple languages and custom alarm sounds Built for real Android limits Background alerts need notification permission. Some phones also need a battery-optimization exemption. If you force-stop the app, Android can pause monitoring until you open it again. Temperature, current, power, and health values come from your hardware — they are not lab measurements. Protect your battery. Charge smarter. Stay informed.
