Did you ever felt, that one ChargerUSB 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.
 It is only good for evaluate which ChargerUSB cable combo is working the best for you on the same device.
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 (USBACWireless)
- 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.
 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 cablecharger configuration. This is a firmware problem.
 The app measures the chargingdischarging 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).
 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.

    Great addition to maximize space for the best uses possible in any application yet devised anywhere. Love it and use it all the time for a lot of different reasons.Simply the best way to test all cables volts and a lot more. A small application it just doesn't take up much space it will give you all kinds of grief useful information.

    Works on some phones but noticed with some phones with fast charging or similar the amps and voltage are incorrect always shows 4ishv even when actually at much higher and shows amps at way higher than the charger is capable of delivering.

    This is the only accurate battery charging app I've ever come across, so much so that you can literally switch between cords, cubes and sockets and see the difference in charging speed.

    Just what you need. Tells me how much is being dumped into my battery. Great for testing "fast" chargers and cable potential. Volt heads will know what I mean.

    My phone battery can't be charge next day after I charge it in full capacity. After uninstall this apps, the phone starts charging normally.

    One of those apps I've used for years across several devices. It does one thing, monitor your battery, and it does that one thing well.

    This app is very nice. It measures and tells me the speed of charging and health of my battery.

    only battery charging information app I can find on the play store or otherwise that is actually legit.. the other apps on Play Store will just show a near constant barrage of intrusive advertisements.. This app is 100% Legit. Some devices may not work on the default setup so you may need to enter the basic settings screen via tapping on the gear icon located in the top right, and then enable old measurements method, or enhanced measuring. Please show the creators mad love by downloading!

    Doesn't show charging voltage, or power. So it's pretty pointless if you want to know how fast you're charging

    Had problems with charging, having this app makes it easier to ensure that electric flow is going into my phone. Works perfectly, easy to use, easy to understand, does exactly what you want it to do. Thanks for the amazing app.
