Power Flow Charging Info

Monitor phone charge in realtime or background: diagnose cables & charger issues

PowerFlow is a charger and battery monitoring app that shows you exactly how your phone is charging or draining in real time. It tracks power flow in watts, voltage, and current, making it easy to see whether your charger is working properly or if a cable is underperforming. High speed and normal chargers supported.

Optionally, the app logs battery data continuously in the background so you can review trends over hours, even when your screen is off. It also helps identify issues like overheating, unusual drain, or inconsistent charging behavior through clear graphs and straightforward diagnostic details such as temperature, health status, and charge cycles, and gives you the option to inspect raw logs when you want more detail.

To keep readings accurate, PowerFlow includes automatic unit calibration on Samsung phones that report non-standard units.
