Did you ever felt, that one Charger/USB cable set charges your device really fast and the other not? Now, you can prove this with Ampere.

Measure the charging and discharging current of your battery. 

PRO features:
- Widgets
- Notification
- Alerts on device 
- Alerts on Android Wear

Not every device is supported because there are devices which lacks an appropriate measurement chip (or the interface) and they can not be supported at all. Please read the list of not supported phones at the end of the description.

The app is not meant to be mA accurate. It is only good for evaluate which Charger/USB cable combo is working the best for you on the same device.

Please read also the FAQ: http://goo.gl/R8XgXX 

----

Start the app and wait ca. 10 seconds ("measuring" is on the display). After this time, the charging or discharging current will be shown.

The current depends on many things:
- Charger (USB/AC/Wireless)
- USB cable
- Phone type
- Current tasks running
- Display brightness
- WiFi state
- GPS state

Please don't use the readings on this app as concrete science. However, the readings are good enough to relatively measure how various chargers and USB cables fair on the same device.

If the app shows 0mA all the time, please use the settings option "Old measurement method". You can force the app with it to use the old measurement interface, if the Lollipop device has at least one.

Unfortunately some Samsung devices don't give correct (measured) values (e.g.: S5), just the maximum possible charging current with the actual USB cable/charger configuration. This is a firmware problem.

----

Background info: The app measures the charging/discharging current of the battery. If your phone is not connected to a charger, you see the discharging current which is negative. If you connect a charger then the current what the charger gives will be used to supply your phone and the remaining power will be charged into the battery.

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

----

Technical info: The displayed current is an average value from 50 measurements minus the 10 upper values and the 10 lower values. The displayed current can be shaky or unstable or even zero which means, that the Android system provides unstable values. Every company uses different battery types and other hardware making it difficult to get accurate results about your charger.

----

LiPo batteries don't draw the maximum for the full time it takes to charge the phone. If your battery is charged almost full then the charging current will be much less as by lower battery levels.

Phones/ROMS compatible only with "Old measurement method" switched on and selected the right "Measurement interface":
➤ HTC One M7 / M8
➤ LG G3

Phones/ROMS reported to be not working 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

Please do not give wrong rating, if your phone is one of the above. Not the app is wrong, but your phone does not support this kind of measurement yet.

If the app doesn't work on your device with pre-Lollipop Android version, then please read the first and the second posts in this XDA developer forum thread: http://goo.gl/pZqJg8 . Please post your problem with screenshots in the XDA thread.

Reviews From google play store

great app does what it says.

Just bought the pro version. can i disable the app icon on status bar without removing the measurement on notification area?

a key icon shown in all widget and main program form, system menu not working and notification data not working

nice app but there is no option for set manual ringtone for alert .. this us very disappointing ....😥

plain and simple, exactly do what it is supposed to do - to measure my phone's amperage; in my case - whenever charging

it works without trying to control your phone

Funciona muy bien, resultados muy exactos

just what I was looking for.

Mto bom!

not bad, but not sure if its accurate

spr
