How Ampere App Works?

Ampere uses the in-built voltage sensors of your Android device to provide accurate measurements of instant battery currents. The sensors sample the power flowing into/out of your battery numerous times per second.

These current samples are then processed using filtering algorithms to display an average current in milliamps or amps. The averages mitigate temporary fluctuations, presenting you with a reliable indication of charging or discharging performance.

For displaying the current readings, Ampere features both numerical and visual representations. The simple yet elegant user interface allows even novice users to quickly diagnose charging issues or monitor battery usage cycles.

Features of Ampere App

Ampere comes packed with useful capabilities to help you optimize battery charging and troubleshoot performance issues.

Charging and Discharging Measurement

The core functionality of Ampere is measuring instant charging and discharging currents. Using the seniors in your device, you can view the average amperage or milliamps over a configurable interval.

Monitoring charge and discharge performance is key to identifying issues and optimizing for longevity. For example, lower than expected charging current could indicate problems with the charger, cable or port. High discharge currents can reveal misbehaving apps.

Pro Features

For power users, Ampere offers advanced analytics and customizations via a Pro upgrade. Pro features include home screen widgets, automatic tracking over set periods, notifications when charge milestones are reached, Android Wear integration and more.


Ampere aims to offer current measurement capabilities across thousands of Android devices. However, due to hardware limitations, some devices that lack certain voltage sensors are not supported. Before downloading, you can verify compatibility with your smartphone or tablet.


The developer puts accuracy as a top priority. Readings are based on an average of samples taken from integrated voltage sensors. The averaged values mitigate temporary spikes or drops in currents. Overall, the analytics provide a reliable indication of battery performance.


A key benefit of Ampere is identifying and diagnosing charging-related issues. Abnormal current readings can reveal problems with chargers, cables, phone connectors and internal charging components. Ampere guides you towards the most likely hardware or software culprit.

By confirming expected charge rates based on the charger used, you can easily weed out faulty equipment leading to slow charging. The app helps mitigate unnecessary costs in replacing functional accessories.
