Description

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.

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.

User's Reivew

4 ★ Awesome little program good enough to pay for the upgrade to pro! Slightissue with Android 7.1.1 and the new Moto E4 Plus. Perhaps the Developerwould like to contact me and I will help fault findby Trevor Hibdige on May 12, 2018
5 ★ I have another app for my Note 8 called Galaxy charging current. Works verywell on the Samsung very granular. This app is quite good, but it displaysvoltage apparently in increments of 10. And a personal irritation, please,please grammar Nazi here......."Did you ever felt" FELT? Really? Did youever think, or believe, did you ever suspect, do you suspect?by Daryl Friedrich on May 12, 2018
5 ★ Is there a way to only boot the app whilst charging? I just want it to onlyshow the amp input in the notification area only when it is charging. Iknow you can turn it off when not charging but that only turns off thenotification and the app is still running in the background...by Kevin Ta on May 14, 2018
5 ★ Your battery voltage reads 3717.934 V which is incorrect. It should read3.717 V. Any more digits are useless because accuracy is not much betterthan 1%.by Donald Pauly on May 14, 2018
5 ★ Fantastic, so good I paid for the Pro version nice clean UI Ideal forchecking out USB cable's and chargers would be great if there was a graphicdisplay that also recorded data overnight ie min Max mah also total mahused to charge phone or tablet to maximum and a timer for example 2300mhaused charge in 3 hours 23 mins keep up the good work and again fantasticapplication.😉by Gerald Read on May 14, 2018
5 ★ This has a battery of information available. Thanksby Glenn Chugg on May 12, 2018
5 ★ It helped me a lot determining the correct power source.by Muhammad Ali Dildar on May 12, 2018
5 ★ VERY MUCH USEFULby ashoka r.n on May 14, 2018
4 ★ Love the app. i would like to see accurate voltage readings for my Droidturbo 2. the charger delivers at times 12 volts whereas most chargers stayat 5 volts. This app never shows above 4.41 volts on my charger. I know mycharger voltage goes to 12 because it burns out lighted USB cables rightaway. Keep up the good work.your doing great.by Kelly D. Sharp on May 03, 2018
5 ★ Helps me to find out what chargers are slow and won't let me listen tomusic and charge at the same time. With my new USB C phone that doesn'thave a headphone jack.by David Llewellyn on May 03, 2018

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.com goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.com can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.com, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.
