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.

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

----

Please read also the FAQ: http:goo.glR8XgXX 

----

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.

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 cablecharger configuration. This is a firmware problem.

----

Background info: 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).

----

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.

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

PhonesROMS reported to be not working with this app:
➤ Galaxy Grand Prime - fortuna3gdtv
➤ Galaxy Note2 - t03g, t03gchn, t03gchnduos, t03gcmcc, t03gctc, t03gcuduos

➤ 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.glpZqJg8 . Please post your problem with screenshots in the XDA thread.

Not showing charging current, doesn't show charge rate and Im not sure what that is at the top in miliamps, but it doesn't apply to what my phone is doing. If thats the charging current, its way off according to 2 different ammeters and the phone itself.

    Much better than expected. This app accurately describes how fast your phone is charging from a charger. I typically buy the cheapest charger available and it showed me I'm getting what I paid for. it showed only 50% of the rated charge versus the original charger was 100% of the advertised charge. Highly recommend to anyone who wants to make sure their phone is charging the way they want it to charge

    I Like this but please make it to where you can change the color of the widget! With a color wheel so I can make it match my halloween themed wallpaper! Make it to where you can change the text and battery at once with a color wheel, and then the key combined with the main. And then the outside to make it transparent fully or less with a tint like a 0 to 100 percent ratio bar. Please do this and then it will be 5 star!

    I love this APP, not only because I am the type of person that loves being able to see what actual performance of something that is a part of my daily life, but because there is nothing more aggravating than trying to determine if your cable, 12 volt automobile adapter, or 120 volt charging power supply is defective. With this app you can find out what is the cause of the "poor charging, or slow charging " alert when you plug in your almost powerless cellular device.

    Does exactly what I needed to do. I was a little skeptical cuz I wasn't sure what went involved with all of this and the development of the app. but once I started plugging it in looking at the car chargers looking at the charger at the house everything worked out phenomenally. I immediately purchased the pro version just to get rid of the ad and support the developer. Well done!!!!!!

    Great, did exactly what I wanted. I compared the rate of charge for all my different cords and USB ports. I do keep getting a message that Ampere is running in the background and using battery, but whatever battery drain it causes seems inconsequential to me. The repeated message is just annoying.

    I absolutely love this app and I highly recommend it. I find it to be accurate in that if I adjust my screen brightness just the slightest bit up or down it is reflected in the app as using more or less milliampers. Money is very tight for me right now or I wouldn't hesitate to buy the pro version of this great app. I hope people will support this fantastic app which unfortunately I can't do at this moment.. Thank you...

    I needed something to test both my chargers and my cables. This app is perfect for that. Sometimes, when I plug in a charger, my phone shows "charging slowly - please check you charger and cable." Without this app, it would be difficult to figure out which was at fault. With this app I compare charging details - which charger puts out the most Amps and which cable transfers the most Amps. The app can be set to trigger alerts and it also has useful widgets. 😎

    It is the simple way of keeping your eye on the most important information to keep going wiith the power you need when you nèed it. I used this often when I would purchase a hard to find C cord a few years ago. I would always test the cheap charge cord when bought at 99-cent store or get one mailed from China usually not great conductors of five volt power at about one amp.

    Works like it says and amazes you how little amperage is put out by a lot of different brand chargers. If you wondered why a device is slow to charge it's probably the adapter or the cord. Just because it says 2.4 amp output doesn’t mean that's what you will get. I have ten different brand adapters rated 2.1 or 2.4 amps none of them put out the same amperage. One says 450 milliamps another goes up and down between 70 milliamps and 1.1 amp. So don't blame your phone.

    A good tool to measure how effective or fast a charger is for the phone. When comparing two chargers one should remember that the amount of battery power which remained ( eg 15 percent) is equal in both chargers, because with increasing battery capacity,the rate of charging decreases. Also put the phone at minimum brightness and airplane mode.

App Neatly shows the throughput in all scenarios within 10-15 secs.. Shows charger output voltage, amps as well.. Happy with this app, it helps you understand if the charger ur using is a normal charger, fast charger or a superfast charger (aka quick charge) or a dumb one overheating to charge ur device.

    Extremely useful program, it helps you evaluate chargers and cables. Unbelievable how much the cable can affect the loading rate. With the same charger one cable can charge at 50 mA and another at 700 mA. Εξαιρετικά χρήσιμο πρόγραμμα, σε βοηθά να αξιολογείς φορτιστές και καλώδια. Απίστευτο πόσο μπορεί να επηρεάσει το καλώδιο τον ρυθμό φόρτωσης. Με τον ίδιο φορτιστή ένα καλώδιο μπορεί να φορτίζει με 50 mA και ένα άλλο με 700 mA.

    I purchased an ads-free version but I still see ads. The 'Charge rate' and 'Max. USB current' values are not generated. But the worst part is total lack of support from the dev.

AccuBattery is a better alternative.

    It works flawlessly, and as intended. It's great to find out if you have a faulty charger or cable and to choose the right one. It even helps to find rogue apps that are consuming your battery as it tells you how much power is been used when not charging. When you connect the charger, it even allows to verify if rapid charge is working or how much charge is coming through. And gives you the temperature the battery currently is.

    After going through multiple charging cords and blocks without a clear idea if any were working properly, I decided to see if there could be an app that would allow me to see how many amps my phone was receiving. A quick search suggested Ampere, and after installing it I went through my cords, charging blocks, and if they would not reach 250 mA they went in the trash. My phone actually prefers over 300 mA, but I kept those over 250 mA to power my other electronics. Great App!

    Accuracy is my issue. The app shows 220 to 190 mAh. The problem is that I don't have my device plugged in. I even cleared data and force stopped it. The fluctuations REALLY concern me because that must be programmed into the app. The only reason to program in fluctuations is if the app is a total fraud. Sure, displaying 200 mAh while not plugged in is bad, but s**t happens. But having that value randomly go up and down indicates the INTENTION to defraud.

So, I downloaded this app. First I open this app, then plugged my charger.The Ampere was reading --(470mA). Then I plug out my charger ,and put it again...... After doing 2to3 times the Ampere was --(1900mA)....... So, the benefit of this app is, it help's to analyse your charger what is giving you the output to your phone. I definitely recommend this app...👌👍

    Good app.. Good interface But some key features is missing. Please add charging time. How much time will take to charge battery & a little bit more info about measuring MA. After this i will give you five 🌟.

    Light and simple app, useful, but it takes about 10 seconds for the app to somewhat calibrate and show the stats --- and some apps show the stats right away ;)

    it doesn't show any measurements in notification panel what's the need of this type of app. It feels that we are not using any app we are using a website which gives us data only when we visit it. LOL...😂😂😂. Never download it.

    Works as expected. Used as basis for charging current. I just wish there is log feature that can record your charging details.

    This app is great, I used to think that my battery had a problem, turns out I had to monitor its performance

    Very good and helpful app. Saved me a lot of money on new charger. Only C type cable was charging very slowly.. Thanks to team Ampere.

    Not sure why, but charging data suddenly dropped from 3 chargers and 2 cables after making temp change in basic settings. Otherwise, it seems handy for verifying your battery and charging information assuming this is just a fluke / bug that I stumbled upon. My A50 still reads fast charging, but current from ports on charger dropped from 2400mA to around 1300 with battery only changing from 62% to 63%. I think for what it offers, it is worth trying out.
