Description

Have you ever noticed that one charger / USB cable only charges your device really fast and the other doesn’t? Now, you can prove it with amperes.

Measure your battery’s charging and discharge current.

Pro Features:
– Widget
– Notification
– Warning on device
– Warning about Android Wear

The app works on Android 4.0.0.3+ devices. Not every device is supported because there are devices that lack the appropriate measurement chip (or interface) and are not supported at all. Read the list of supported phones at the end of the description.

The application was not meant to be MA accurate. It is only good to evaluate which charger / USB cable combo is working best for you on the same device.

Start the application and wait for the CA 10 seconds (“Measure” is on display). After this period, a current of charging or discharge will appear.

Depending on a number of current issues:
– Charger (USB / AC / Wireless)
– USB cable
– Phone type
– Current work in progress
– Show brightness
– WiFi state
– GPS state

Please do not use the readings of this application as concrete science. However, the readings are good enough to compare how different chargers and USBs just lighten up on the same device.

If the app always shows 0 mA, Please use the “Old Measurement Method” option in the settings. If the Lollipop device has at least one, you can force it to use the old measurement interface.

Unfortunately some Samsung devices do not give the correct (measured) value (e.g. S5), only the maximum possible charging current with actual USB cable / charger configuration. This is a firmware issue.

Background information: The application measures the charging / discharge current of the battery. If your phone is not connected to a charger, you see a discharge current that is negative. If you connect a charger, what the charger gives will be used to supply current to your phone and the remaining power will be charged to the battery.

If your phone consumes 300 mA without a connected connected charge (-300 mA on display), the 500 mA charger will charge your battery with a maximum of 200 mA current (200 mA on display).

Technical information: An average value of 10 higher values ​​and 10 lower values ​​of the current 50 measurements displayed. The current displayed can be shaky or unstable or even zero which means, the Android system provides unstable values. Each company uses different types of batteries and other hardware to make it difficult to get accurate results about your charger.

The LiPo battery does not draw most of the time it takes to charge the phone. If your battery is almost fully charged, the charging current will be reduced by the lower battery level.

Phones / ROMs are only compatible with the “old measurement method” and have chosen the right “measurement interface”:
HTC One M7 / M8
LG G3

Phone / RMS reported not working with this application:
Galaxy Grand Prime – Lucky 3 GDTV
Galaxy Note 2 – t03g, t03gchn, t03gchnduos, t03gcmcc, t03gctc, t03gcuduos
Galaxy S3 – D2AT, D2 SPR, D2 VMO
Galaxy Tab 4 7.0 – Digas 3G
HTC Desire 510 – htc_a11ul8x26
HTC One S (Villi), X (Endeavor), XL (Avita)
HTC Sensation 4G – Pyramid

If your phone is one of the above, please do not give wrong rating. The app isn’t wrong, but your phone still doesn’t support this kind of measurement.

If the app doesn’t work on your device with the pre-Lollipop Android version, please read the first and second posts in this XDA developer forum thread: goo.gl/pZqJg8. Post your issue with screenshots in the XDA thread.

Note: When the ampere is stuck in the “measure” state (after upgrading the firmware to Android xx) please clear the ampere application cache.
1.) Open “Android Settings App” => “Apps” => “Ampere”
2) Clear all data in the “Storage” menu
3) Turn on the ampere
