The Ampere app is a useful tool for measuring the charging and discharging current of your smartphone battery. Developed by Brain_trapp, it helps users evaluate the performance of different chargers and USB cables, and provides insight into the health and power consumption of your battery. While not a scientific tool, Ampere offers a relative metric to help you choose the best charging settings for your device. The app automatically measures the current when you open it and displays various battery information such as charge level, health, and temperature. It is available in both free and paid versions, with the latter offering additional features such as widgets and notifications. This app is especially useful for optimizing battery life and keeping your device powered up throughout the day.
FEATURES
Charging and Discharge Current Measurement
The Ampere app allows users to measure the charging and discharge current of their smartphone battery. This feature is essential for understanding how different chargers and USB cables work. When connected to a charger, the app displays the current being delivered to the battery, while a negative value indicates that the battery is being charged when the charger is not connected. This helps users compare the efficiency of different charging configurations and determine which combination is best for their device.
Battery Information Display
Ampere provides detailed information about the battery’s charge level, health, status, technology, maximum capacity, temperature, voltage, and more. This comprehensive overview helps users monitor the health and performance of their battery over time.
Widgets
The Pro version of the Ampere app includes widgets that users can place on their home screen. These widgets provide quick access to battery information and charging status without having to open the app. This feature is useful for users who frequently check their battery or want to keep track of their charging progress in one place.
Settings and Configuration
Ampere offers configuration options, including the ability to switch to the “Legacy Measurement Method” for some devices, especially those running older versions of Android.
Relative Charger and Cable Comparison
The measurements in this app are not scientifically accurate, but they are reliable for comparing the performance of different chargers and USB cables on the same device. This feature helps users determine which charging settings will give the best results for their phone model.
Notifications and Alerts
The Pro version also offers notifications and alerts, which can notify users when the battery reaches a certain level, such as when it is fully charged or low. Additionally, you can set alarms for Android Wear devices, allowing users to seamlessly integrate with their wearable device.
