Ampere
You can install Ampere form Google Play or you can download the lates APK from here.
Measure the charging and discharging current of your battery.
The app was at first designed for Lollipop only, but now devices with Android 4.0.3+ are also supported. Please read the pre Lollipop forum..
How to use the app: 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/Wiereless)
The USB cable
The phone type
Current tasks running
Display brightness
With this app you can for example search for an optimal charger/USB cable combo.
The app is not meant to be mA accurate. It is only good for evaluate which Charger/USB cable combo is good for you.
Background info: The app measures the battery charging/discharging current. If your phone is not connected to a charger, you see the discharging current which is negative. Now, 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, then a 500 mA charger will charge your battery maximum with 200 mA current.
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 just zero which means, that the Android system provides such unstable values. Some phones, like the Nexus 4 reports such unstable wide spreading readings when charged with a low current charger (e.g. 500mA), that even the average value is just a joke.
Background info about batteries and how they will be charged: 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.
A nice article explaining LiPo charge stages: http://batteryuniversity.com/learn/article/charging_lithium_ion_batteries
Dave's (EEVBlog) LiPo Charging Tutorial:
If your Lollipop device (or later) shows 0 all the time: There are Lollipop devices which don't have a working power profile (the new Lollipop interface to get the measured current). But on some of them is the old interface still present and maybe also working. Please use the settings option "Old measurement method" in this case. You can force the app with it to use the old interface, if the Lollipop device has at least one. Maybe it helps...
If the app doesn't support your device, you can collect some info to help. Please read this post in this case.

Please report your experience with your phone/ROM type.
If a device has an erroneous or dummy implementation of the Power Profiles for Android, then the app will never support it or the app will just show the erroneous or dummy values delivered on the interface. Please ask your ROM developer to implement it correctly.

awesome ! downloading it!
Cool!!, Trying Now
in the discharge i see 230ma. why not -230?
when charging i see 860ma. is it 860 total or 1090-230?
WOW, great app, i was waiting for a long time! great!
Downloading and testing!
Good looking app. Seems handy to have too
0mA
M7 CM12 Nightly Nuk3rn3l
EDIT: and my data transfer speed from PC to phone was barely above 0kb/s, till I killed app (from cache)?
Any app similar to Android 4.4?
Thanks
I reached the cap
My vooc charger reached the cap which seems to be at 3000mA, it comes back to 0mA.

Measure the charging and discharging current of your battery.
The app works only on Lollipop (Android 5.0+) devices.
Start the app and wait ca. 10 seconds ("measuring" is on the display). After this time, the charging or discharging current will be shown.

Great Work!
Perhaps you want to consider adding a real-time widget and some tasker integration to improve your app even more! Just ideas to make your app even better.
Ah just forget it, i didn't see [5.0+] xD
How is this different than CurrentWidget? Okay, yours looks much better but CurrentWidget sits on page 2 of my homescreen, happily tucked away...
awesome app .
tx so much
really useful.
Showing 0ma for Note 2 Internation version on cm12 5.0.2
Waiting a long time for an app like this!
Thanks!
Would it be possible to make it "locale" plugin? I would like to have toast when charging isn't full speed.
Very nice app!
Should be nice to have some kind of service that would enable stats or graph over time even when using other apps in system, that could also work in background to measure in screenoff
Hi,
Does this get info from:
cat /sys/class/power_supply/battery/*
If so why does it only support lollipoop?

That was going to be my question but you beat me to it
Switched to J7 Prime from Redmi Note 4 for some reason, but TouchWiz UI straight off is less friendly. And with no sound enhancement comparable to Mi Sound Enhancer :silly: I also lost my Mi Cloud photos. Need MIUI!!
hey guys i was wondering will samsung bring over the features on the S9 to the S8
E.g ARemoji Intelligent Scan basically cause looking in the past they did the same with the S7 they brought over bixby to the S7 and S7 Edge so i am curious will samsung bring the S9 Features to the S8 & S8 Plus
