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.
Ampere Apk is an application that helps its users in checking the voltage of their battery. It was developed by Braintrapp web developers. The current flow depends on many factors. Some being the cable that the device is connected to either the USB or the wireless, the phone type, the tasks that are running in the background, the brightness percentage or the GPS state.
It also depends whether or not the wifi is connected and turned on. Ampere Apk lets its users check whether or not the battery is charging. And if it is charging then at what pace is it doing so. When the user has no charger connected to the device on which they are using Ampere Apk, then the app shows a negative signal while as obvious, for a positive signal the charger needs to be attached with the device. The app tells the user of the current in just 10 seconds.
Measure the charging and discharging current of your battery.
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.
Measure the charging and discharging current of your battery.
PRO features:
– Widgets
– Notification
– Alerts on device
– Alerts on Android Wear
The app is not meant to be mA accurate. It is only good for evaluating 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:
– The charger (USB/AC/Wireless)
– The USB cable
– The 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 your Lollipop device (or later) shows 0 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. Maybe it helps…

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.

* Bug fixes and minor enhancementsAmpere FAQ: http://goo.gl/R8XgXXFor more info please read the change history: Settings => About Ampere => Change historyNote: When ampere would be stuck in “measuring” state (after a firmware upgrade to Android 7.x) please clear Amperes’ app cache.
1.) Open the “Android Settings app” => “Apps” => “Ampere”
2.) Clear all data under the “Storage” menu
3.) Restart Ampere
USER REVIEWS/OPINION:
- COOL! This app has taught me a few good pointers. I have more knowledge when it comes to charging my devices. I can compare different chargers and cables by testing them myself. No more need to waste money on misleading products thanks to Ampere. Shout-out to Brian Trapp, Thanks!
- Great app to check voltages and currents in use. Easy use for evaluating chargers and cables quality. I have a problem with it though. The battery full/low/hot alerts only make my Redmi Note 5 AI (MIUI 10/Android 8.1) vibrate. No sound is played. Tried changing sounds and all types of troubleshooting…
