Ampere

Ampere Ampere helps you measure charging current and battery consumption in real time. Compare chargers and USB cables, view detailed battery reports, and get alerts to keep charging safe.

Ampere

Ampere helps you measure the charging current your device receives and track how much power it consumes. If you’ve ever noticed that your battery behaves differently depending on the charger or USB cable you use, this app explains why. With Ampere, you can determine which charger works best with your device—so you can help extend battery lifespan and overall usage time.

Features

• Measures the current drawn and the current released by your phone while it’s connected to a charger or USB power source.
• Results can vary based on your device model, the charger, your current operating state, and screen brightness.
• Charging is not always fully completed in the same way for every session/time period.
• If you’re using a device running Lollipop and it has only one connection interface, you can switch to an older measurement method.
• Uses an intelligent notification system to alert you about relevant charging and battery conditions.

Highlights

Ampere focuses on charging-current information and shows battery-related status at the same time. With the app, you can review detailed battery reports, including things like:

• Power delivered from the battery
• Whether your device is using an AC charger or another power source
• Parameters tied to your device’s temperature, helping you keep operation safer

Quick to get started

Even though Ampere provides useful capabilities, it’s designed to be easy to learn. Most actions are optimized and handled automatically. After installing, simply open the app, log in, and wait about 10 seconds for Ampere to display the information it collects. It also presents key data about factors that can affect differences in charging performance.

Use utility widgets

In addition to showing information on the app screen, Ampere lets you add home screen widgets to monitor your device continuously. Turn on the widgets you want—such as:

• Charge status
• Battery percentage
• Temperature
• Other measurement readouts

Widget options are presented clearly with different colors and designs, making it easier to stay aware of your device’s condition without repeatedly opening the app.

Important warnings and alerts

Ampere can send ongoing alerts so you’re always aware of what’s happening. To get the full benefit, you’ll need to grant the app access to the device’s system control memory. The app is not intended for harmful behavior like stealing data or spreading malware. After you allow notifications, you may receive alerts related to battery and charging current—such as:

• When the battery overheats
• When the charging current is too high or the voltage is not within a safe range
• When charging doesn’t appear to be working properly
• Other abnormal conditions
