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
The app works on Android 4.0.3+ devices. 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 Charger/USB 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 (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.
 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.
----
 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).
----
 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.

I'm a carpenter so my Galaxy Note9 gets used A LOT! Sometimes I don't notice how hot it's getting until this app warns me. I actually fried my Note5 because it got too hot. This app has literally saved my Note9 more than once. It's the best free battery/charge monitoring app I've ever used. It works so well that I even got the paid version! An absolute MUST HAVE for anyone that relies on their device as much as I do & actually wants to protect it! 10/10

It says in the description "Android Pie release" but ever since I updated my Galaxy Note 9 to Android 9 and try to use the app it will just show "measuring" and not be able to display current battery amperage. Will give back 5 stars when issue gets fixed.

Good app, i use it to assess chargers and other peripheral power related gear. I gave it 5* a long time ago and refresh it whenever i get an update but still get hassled for a review, might remove a star each time it occurs going forward.

Used the free version for a while but went for Pro to support the developer. Great little piece of software, it helps me to determine if the charger and cable combo is able to deliver as much current as the phone or tablet demands. Bear in mind that your Android device also automatically regulates the current input, so it's equally important to note the maximum current draw, not just how much the device is asking for power at any given moment.

Ampere does what it says, just slightly better than most other apps of it's kind. On install, phone was unable to connect on calls. Uninstalled, rebooted, reinstalled, no issue so far. App remains open when not in use, must be closed using maintenance apps.

Excellent app. Helped me solve a complex battery/charger/tablet issue. Realised thanks to this app showing the real charging intensity in mA that my 3m long extra quality USB cables were preventing the effective charging of my device..

Very reliable when showing my battery charging rate. I wonder why my phone is not charging fast enough at times and this app show me the current rate which explains it slow low charge rate. Always handy on informing me.

Simple to use. It gives me the info without the hassle/cost of buying special equipment. It does have ads, but it is so unobtrusive, I don't mind giving the developer some earnings (however little that is 😏)

okay, but it keeps resetting when you're screen times out. I'd like it to run in the background to give a decent measurement

I Iike the app. Beside of the good information during charging I can check also if my cables are fast charging or not. Even the adaptors. So although I will not use the extra pro option I bought the app to help the developers to continue the app. Great job.

ampere is good app. measures well. I like to watch it freak out when I plug my phone into a power supply and crank it up to 30V. Is fun.

If I can purchase the pro version on the Google Play Store, I will give this app five stars. However I do not want to purchase the pro version via an add-in purchase. All in all this is an excellent app. I love it. I like its widgets. I just want to be able to purchase the pro version in the Play Store. Until then, I may uninstall it and find an alternate app.

It's perfect! A lite app that does EXACTLY what it promotes. Keep em comin, Devs!! Thank you. (: HELPS ME FIND THAT ONE USB CHARGER THAT'LL ACTUALLY CHARGE. DERKA

Showed me the 2.4 Amp charging cords I bought max out at 1.2 Amps. Talk about a ripoff, I recommend getting this app to make sure you get what you pay for

Very good app to test if phone it's charging at what rate when connect to PC or laptops or wall sockets or test your USB cables how fast they charge your phone, therefore it's deserves 5 stars ☆☆☆☆☆

Basically does wat it says, lots of devices say " may not b optimised 4 ur device" ignore that, by swapping leads & chargers allows u to find best combination for best / quickest charging, very useful 👍

fake app.. let me tell first i tried it with 2A charge it gave me a reading of 1A and same with 1A and .25A charger also and let me tell all these charges are original and i got them with the phone..

Nice app to know the strength of yur charge or charging cable. I am not sure if it measures accurately the battery maximum amperage but as an overall App, it stands out as one of best.

Очень хорошее и полезное приложение! Очень просто в понимании. Теперь я знаю о своем аккумуляторе все, что нужно. Спасибо! || Very good and useful app! Very easy to understand. Now I know everything about my battery. Thanks!

make the app lighter. the description given downside is repeated multiple times.
