Wattage — Battery Current

Wattage shows what your phone's battery is doing right now. LIVE BATTERY CURRENT • Current in mA: + while charging, − while discharging • Power in watts, calculated from voltage × current • Charge level and charging state • Voltage and temperature • Last 90 seconds of current as a small graph BATTERY DETAILS • Health state reported by Android • Health percentage when the device exposes full and design capacity • Cycle count on Android 14+ or when the device exposes it • Full-charge and design capacity • Battery technology and power source SIMPLE AND PRIVATE • No ads • No account • No analytics • No internet permission • No data collection HONEST LIMITS Android does not expose every battery value on every phone. Missing values show —. Cycle count requires Android 14+ or a readable system node. Health percentage requires both full and design capacity; many phones hide them. Current readings are device estimates, not calibrated test equipment. Wattage is not a laboratory meter.
