🔒 100% OFFLINE & ZERO PERMISSIONS Your privacy is our top priority! This app is fully offline and requires absolutely NO extra permissions. No internet tracking, no data collection—just a safe, secure, and perfect battery check experience directly on your device.

⚡ DYNAMIC CHARGING STATS Measure the actual power flowing into your device! Check your real-time charging current to instantly verify if your phone is charging Fast, Normal, or Slow. Keep an eye on live Temperature (°C/°F), Voltage, and Health status to protect your device from overheating.

🔍 SMART CHARGING DIAGNOSTICS (NEW!) Ever wonder if your cable or adapter is underperforming? Our new Smart Check feature helps you find out! Simply enter your charger's adapter wattage (e.g., 33W, 65W), and the app will compare it with the live power received by your phone.

- Detect Slow Power: If the power is lower than expected, we’ll advise you to check your adapter, cable, or clean your charging port.

- Smart Analysis: The app waits a few seconds after plugging in to let fast chargers negotiate speed, preventing false alarms.

Note: Diagnostic results are estimations based on real-time hardware data and user input.

📈 ADVANCED RECORDS & ESTIMATES The app goes beyond basic stats by automatically tracking your data:

- Historic Logs: Automatically records your Highest, Lowest, and Average temperature, voltage, and current over time.

- Smart Predictions: Get highly accurate estimates for Screen-On Time and Standby Time based on your remaining battery capacity.

🕒 DETAILED HISTORY LOGS Keep a timestamped record of every charging session. The app logs every time you plug and unplug your charger, tracking total charging "Starts" and "Stops" so you can perfectly understand your daily charging patterns.
