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: 


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.

- Dave's (EEVBlog) LiPo Charging Tutorial:


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: . Please post your problem with screenshots in the XDA thread.

    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.

  2. Atma Darkwolf-avatar

    definition Very difficult to judge, the ads at bottom of screen, regardless what you choose when you close, is always same ad, and it chugs away at battery use (ie battery charge should show 1000-1200ma normally while charging, but the ad alone reduces this to 700-750ma) If there was a way to just block ads completely, this app might be worth using. (IE a paid version without ads?)

  3. Kelly McGarghan-avatar

    Kelly McGarghan


    meter 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.

  4. Iam Trouble-avatar

    berechnen This app works. It does what it claims to do and I did not experience any problems. Since I discovered ampere (I make sure it's the one by braintrapp), it had been a staple on all my android devices. It is so easy to use, you install, then open and you see it's measuring. After a couple seconds a measurement is displayed. Current is measurement that must be taken over a duration of time, the result being an average. One mi ch t mistake this delay fir latency. It is not.

  5. Sven Hoff-avatar

    in watt The App does what it claims to do. So far i can not say anything bad about the App. But it would be really nice to also show the Charging Voltage that comes from the charger (if possible). I had problems with the original Samsung Note 10+ charger in combination with my wireless charger. The Qi wireless charger does not used the 9V charging mode with the Samsung charger. When i use it with a Blitzwolf charger it workes without any problems in 9V mode. But i was only able to test it with a Hardware USB Meter. Would have been nice if Ampere were able to show the Voltage comming from the charger so additional hardware is not needed! Also a logging funktion with graphs would be nice! For this additional funktions i would gladly pay.

  6. Jeffrey Huang-avatar

    stunden Great app. I use it all the time I often have problems with charging my phone and it just helps my peace of mind that it's charging and I love how it tells you how fast it's charging. Would totally recommend for people with charging problems or just for peace of mind.

  7. Gregg Geigler-avatar

    in ma As the developer says, this app indicates the approximate current flowing into the battery- NOT the total current being consumed by the phone/tablet. This can be proven with the use of an inline USB ammeter (i.e. Charger Doctor) which indicates total current draw by phone/tablet.

  8. Andrés Vázquez-avatar

    Andrés Vázquez


    nvidia I've used this app for so long and it's very cool. It tells you specific information about your device. Recently I bought a new device the OnePlus 7t McLaren edition. It says that the max capacity is 3,300mah. The device max capacity is wrong. It's 4,085 mah. Other than this problem or bug the app overall is good👍.

  9. Kevin Kendall-avatar

    umrechnen This ampmeter app does just one simple thing & one thing only, and very well: showing the rate of charge (*and* running foreground/background apps & the GPS & screen brightness, & etc other subsystems' effect on the battery's rate of discharge, useful for some elusive energy-drain troubleshooting). This retired electrician gives 5 solid 🌟 for Ampere's simplicity, effectiveness, accuracy, & lack of annoying "mosquito ads."

  10. Suhandi Wiratama-avatar

    messen Best of the best. I have compared three related apps for measuring charging speed. And I've noticed this is the best and the most accurate app to calculate the ampere. Now I know why this app got the highest rating for the related feature! Thanks Mr. Developer! Update: After the March 23, 2020 update, the algorythm got much better. Nice job.

  11. Lie Gaye-avatar

    Ampere is one of the more reliable Battery apps out there. The app provides useful info like battery health, temperature and discharge rate of your phone's battery. The interface is simply and has support for dark mode. I would like to see more alert options like 80% charge level for those who don't like to charge to full. Nonetheless it's a great app. Well done!

  12. Sayan De-avatar

    This app does what it says. It measures the current your phone is receiving from the charger. It helped me confirm my suspicion that the charger wasn't providing even half of what it should be able to provide. It's simple yet amazingly helpful, and it also provides some battery related info like temperature, etc. for those of you who might need it for additional troubleshooting or just for daily monitoring.

  13. Ernie Lacaillade-avatar

    An excellent tool that helped me realize what apps. were umneccessarily draining my battery. Great for identifying old, worn out or broken chargers. What they say isn't always what they put out.. Very happy with this app. Developers I salute you.

  14. Dan Regan-avatar

    This is a great app! Was having problems with my battery, did not know if it was taking a charge or not. Install this app answered all my questions immediately. Would recommend it to anybody with battery issues!

  15. Albert Flor-avatar

    Nice apps! I found an accurate power consumption of my phone under charging or check consumption when not charging and other data specifically operating temperature plus other phone valuable information! Kudos to the developer, like it very much!

  16. Albert Sany-avatar

    A nice "To the point" app without ads. Very easy to use. Now I know that my charging cable is broke that it charge very slowly below 500mA (the normal one is around 1.1k mA, and my phone is not fast charging supported)

  17. For You-avatar

    I gave five stars because this app works with over 90% of phones i've tried, which has been over 50 phones . its hard to get any app to do that! Love the dark theme.. It also helps me throw out the bad chargers and cables, lol. Thanks for a great app. And not overloaded with adds . Great job!!

    So when I needed an app to give me feedback about my malfunctioning Nexus 5 battery I downloaded like 10 of these apps. Most were trash, some were ok and two were pretty good. This one wins hands down. I honestly have nothing bad to say. It helped me find out I needed to replace my battery. I still use it every day just to monitor things in my Nexus 5X. I paid for no ads because support the developer ya bums.

  19. Ben Smith-avatar

    Simple, specific, elegant, effective. It's not encumbred by useless fluff like many other apps are. It does the job, only the job, and it does it well. What more could I ask?

  20. Brano Stredak-avatar

    yeah. measures amperes. 😊 great. for be sure about your cable or charger. or for compare more pieces. similar numbers than standard multimeter. little bit higher than reality mostly but still valuable information.

  21. Quentin Moten-avatar

    The app is lessening my battery charge and I don't know what to do. It is just a waste of time to have and have turned off my data and everything else but I don't get a faster charge input information. You need to update the system to the year 2020 phone service's.

  22. chugs Rodríguez-avatar

    Efficient, fast, useful, user friendly, pro ver is very affordable and does exactly what you need. Makes you wonder why it's not a native function in Android.

  23. Esrom Manalo-avatar

    What happened? I already paid for this app and now it's asking again if I want to removed ads and to use the notification feature again? Whut??? I have my proof here in my Purchase History. Edit: The developer promptly replied to my email and everything is fixed now.

  24. Gabriel Iniguez-avatar

    Great app to monitor basic charge and discharge rates, but would be nice is it had a bit more options for the data being generated. Even a basic time lapse time chart or record function to link up with or added to the app itself would be nice. Otherwise a nice app to monitor Current levels.

  25. Vijay Uppara-avatar

    One of the best app. I literally compared 2 cables. The first one showing 200 mah and second one showing 1050 mah and i can immediately decide which cable was faulty. The second cable was showing result

  26. piyush anand-avatar

    My device was taking very long to get fully charged, so i tested many usb cable, and got the right usb cable with the help of this app, 5v2amp charger will give approx 1820+ Mah for the first 15% and thwn decreass considerably (in my case) with boat rugged v3 cable, so i recommend all of you to download this awesome app

  27. Alan Stinchcombe-avatar

    Alan Stinchcombe


    Excellent tool! Need to remember that, when charging, it only measures the current to the battery. In addition, the charger is delivering hundreds of milliamps to the device, as seen when you disconnect the charger.

  28. sayan das-avatar

    This is a gimmicky app. Shows me same current values with and without fast charging turns off. Seems like it just calculates some random values based on the phone model number. Since my phone is new it doesnt know this has fast charging

  29. Kolawole Ojo-avatar

    I started using this app few days ago and it's has been working well, that's why I'm giving it 3 star for now. If it doesn't mess up, i will come back and give it 5 star

  30. Dennis Jahnke-avatar

    This is literally the only app/widget that monitors (in my book) the big three: Amp Draw Temperature Charge Level I would have given it 5 stars if I could make tha widget a little bit bigger, and increase the size of the text even bigger than you allow. Any chance of adding resizing? Dennis

  31. Arnis-avatar

    You can see charge-discharge rate. But can't actually register it when screen is off. No graph capability. No alarm capability.

    I was challenged with my phone charging very slow sometimes. This app gave me insight into which adapters, power cords and even which outlets in my home were best to use for charging. So easy to use.

  33. Juan Guerra-avatar

    Yes,it works perfect. I use it to check if the power adapter and cable are really charging my phone. Thanks.

  34. Phil C-avatar

    Works great! Use it to test cables and chargers. Thought my battery was going bad, but it was the charger putting out a quarter of the normal voltage.

  35. Wayne GIlpatrick-avatar

    Wayne GIlpatrick


    It's great it does everything they said it would. It keeps up with every little detail of your battery. If you want to know what's going on with your cell phones battery this is the app for you.

  36. Chris Pearson-avatar

    Worth the money! I've searched every batter measurement app 9n the store and nothing comes close. Many options, custom notification, accurate readings!

  37. Shah Din-avatar

    Good app. I am using this with my P20lite which shows 200 mA less current readings. I suggest to make manual calibration so that user may add or subtract to current or voltage values to display the exect values.

  38. Dave Rice-avatar

    I feel it shows an accurate charge/amperage ratio as well as battery drain meter. I've had this app on 3 devices and it has shown according to that tech.

  39. Marcin Paweł W.-avatar

    Marcin Paweł W.


    Works quite well. Results are slightly lower than accurate measurement on input, but that's to be expected.

  40. Paul Mitchell-avatar

    Really useful and informative app. I'm curious why my USB tester says that the amp draw is different than what is reported by the app.

  41. Ivan Rowland-avatar

    Great.. Very useful.. early days yet but it works fine..AA++ Still a very useful app to me, I often use it to check the wireless charger I made for use in my car, is still working ok.

  42. Steve Ng-avatar

    It tells me how many milliamps the phone is drawing while charging. This helps me diagnose the condition of my charging cables and chargers.

  43. Burl Thomas-avatar

    Does what it says it can do and does it well! Very easy to use, really nothing to learn. Totally intuitive...

  44. John Sterling-avatar

    worked great! was able to tell one port of car charger was only 650mA but the other is 1200mA. Now I'm using to test wireless charger vs corded. Wireless fast charging is 1/2 corded. Good to know

  45. Eeen Dowsett-avatar

    does what it says very well. removes an entire layer of electrical troubleshooting when you're trying to resolve charger/cable/idiot-proprietary-charging issues (mostly, cable wires break with use much more than you'd expect)

  46. Devyanshu Sharma-avatar

    Devyanshu Sharma


    This app is excellent because it provides a current information about the battery my phone 📱 is 20% charge in 2 hours but now 50% charge in 1:30 hours

  47. Mark Roy-avatar

    Good app, does the job accurately and clearly while keeping ads to a much-appreciated minimum. Wish other developers would behave like this! Will pay for the pro version in thanks AAA+++

  48. Rick Fambry-avatar

    works great on phones, DOES NOT WORK ON CHROMEBOOK. I love this app and use it on my phone but I thought I'd try it on my galaxy chromebook and it just says UNKNOWN. Just thought I'd let you know so it can possibly be fixed.

  49. Glen Gleaves-avatar

    Best app out there for measuring charge rate and for testing different cables and chargers for problems. I use Ampere daily on all our Android devices and have relied on it for years!
