Details for this app
Ampere Pro measures battery charging and discharging current so you can compare how different chargers and USB cables perform on your device. After you start the app, it takes about 10 seconds to display a reading. When the phone is unplugged, the app shows discharging current; when connected to a charger, it shows the current going into the battery after the phone’s own power use is accounted for.
Readings are intended for comparison, not as precise measurements. Results can vary with the charger, cable, phone, battery level, and device activity, and some devices lack the hardware or interface needed for measurement. The listed Pro features include widgets, notifications, alerts on the device, and alerts on Android Wear.
