Live Charging

About this app

Live Charging turns your Android device into a clear real-time charging dashboard.

Watch estimated net battery-input power update every second on a speedometer. Follow small changes on a tightly auto-zoomed graph with raw and smoothed traces, and switch between 30-second, two-minute and five-minute windows.

Compare your current session with a clearly labelled 10.4 W public crowd average. When that baseline falls outside the zoomed graph, an edge marker keeps the comparison visible without flattening the live detail.

The dashboard also shows battery level, charging state, power source, current, voltage, temperature, rolling average and session peak.

Measurements use Android's on-device battery current and voltage readings. They estimate power reaching the battery, not USB-port or wall-charger output. Results can vary with the device, charger, cable, temperature, battery level, screen use, conversion losses and firmware. Some devices do not expose a usable current sensor; Live Charging reports that limitation instead of inventing a value.

The public baseline is a directional comparison based on a documented snapshot of public charging benchmark results. It is not a pass/fail threshold or a charger specification.

Live Charging has no ads, accounts, analytics, cloud service or in-app purchases. Battery readings remain on the device. The app requests no runtime permissions and does not request Internet access.
