Charge Meter: Battery Monitor

See what’s happening at your battery while your phone charges. Charge Meter displays live battery readings in a clear, dark interface with an analog-style current dial and a short live chart. Compare readings while trying different chargers and cables, and see how your phone’s activity affects the current reaching the battery. Features: - Live net battery current - Battery voltage and estimated battery-side power - Battery temperature and charge level - Android-reported battery health status, where available - A short live chart to help you follow changes - Details explaining the readings - Automatic screen-on mode while the app is visible Understand your readings Positive current means power is flowing into the battery. Negative current means the battery is supplying power. Your phone’s own power use affects these readings, even when a charger is connected. Estimated power is calculated from battery current and voltage. It is not a direct measurement of your charger’s output or your cable’s maximum wattage. Availability and accuracy depend on the device. Some phones may not provide every reading. Android’s battery health status is not a battery capacity or wear percentage, and Charge Meter does not certify fast-charging performance or diagnose faulty accessories. Privacy and use Battery readings are displayed on your device and are not saved as charging history. Charge Meter does not record charging sessions in the background. The screen stays awake while the app is visible; you can still lock it with the power button. The app contains ads provided by Google Mobile Ads.
