Ampere v4.12 Mod APK Optimize Your Device Charging with Ampere

Have you ever wondered why some charger/USB cable sets charge your device faster than others? Now, you can put this to the test with Ampere.

Measure Charging and Discharging Current

Ampere allows you to measure the charging and discharging current of your battery with ease. With this app, you can gain insights into how your device charges and discharges, helping you make informed decisions about your charging accessories.

PRO Features:

  • Widgets
  • Notifications
  • Alerts on your device
  • Alerts on Android Wear

It’s important to note that not all devices are supported due to the absence of an appropriate measurement chip or interface. For a list of unsupported phones, please read the FAQ section at the end of this description.

Please keep in mind that Ampere is not meant to provide precise mA accuracy. Its primary purpose is to help you determine which charger/USB cable combination works best for your device.

Getting Started with Ampere

To begin using Ampere, follow these simple steps:

  1. Start the app and wait for approximately 10 seconds (the “measuring” message will appear on the display).
  2. After this brief period, the charging or discharging current will be displayed.

The current your device receives or discharges depends on various factors:

  • Charger type (USB/AC/Wireless)
  • USB cable quality
  • Phone model
  • Background processes
  • Display brightness
  • Wi-Fi and GPS state

While the readings provided by Ampere are not scientifically precise, they are reliable enough to compare the performance of different chargers and USB cables on the same device.

If the app consistently shows 0mA, consider enabling the “Old measurement method” in the settings. This option allows the app to use the older measurement interface, provided your device is running on Lollipop or later.

It’s worth noting that some Samsung devices may not provide accurate measured values, displaying only the maximum possible charging current with the current USB cable and charger configuration. This issue is related to the firmware of these devices.

Understanding the Charging Process

Ampere measures the charging and discharging current of your device’s battery. When your phone is not connected to a charger, you will see a negative discharging current, indicating power usage. When you connect a charger, the charger’s output will be used to supply your phone, and any remaining power will be used to charge the battery.

Keep in mind that the charging current may vary depending on your battery’s current state. For example, if your phone consumes 300mA without a charger connected (-300mA displayed), a 500mA charger will charge your battery at a maximum of 200mA (200mA displayed).

The displayed current represents an average value derived from 50 measurements, with the top and bottom 10 values excluded. As a result, the displayed current may appear shaky or unstable, or it may occasionally show zero. This variability is due to differences in battery types and hardware across various device manufacturers.

Additional Resources

For more information on battery charge stages and LiPo batteries, please refer to the following resources:


Phones/ROMs that are compatible only with the “Old measurement method” activated and the correct “Measurement interface” selected include:

  • HTC One M7 / M8
  • LG G3

Phones/ROMs reported to be incompatible with this app:

  • Galaxy Grand Prime – fortuna3gdtv
  • Galaxy Note2 – t03g, t03gchn, t03gchnduos, t03gcmcc, t03gctc, t03gcuduos
  • Galaxy S3 – d2att, d2spr, d2vmu
  • Galaxy Tab4 7.0 – degas3g
  • HTC Desire 510 – htc_a11ul8x26
  • HTC One S (ville), X (endeavoru), XL (evita)
  • HTC Sensation 4G – pyramid

If you encounter compatibility issues, please do not rate the app negatively; the problem likely lies with your phone’s support for this type of measurement. If the app doesn’t work on your device with a pre-Lollipop Android version, read the posts in this XDA developer forum thread for guidance.
