If you want to help, please do the followings:
  1. Please install the latest Ampere
  2. Start the System Info screen: Touch 6 times the Build version in Settings/About Ampere
  3. Without leaving the System Info please share the outputs with me. The easiest way is to save (share) to Drive/DropBox or somewhere others one by one. Later you can put the files from there in your post as attachment.
  4. The test cases:
  • No charging -> push refresh -> share
  • USB charging -> push refresh -> share
  • AC charging -> push refresh -> share
  • Wireless charging -> push refresh -> share
  • Fast/Quick charging -> push refresh -> share
Please do not forget to rename the files or to give a proper description (No Charging, USB charging,...) by sharing

Hi guys! Hi Nihilo!
Old occasional Ampere user, but just now noticed the cute lil widget it had and wanted to add it to my homescreen. I'd gladly purchase the license, no problem, but i'd have one question first, if i may: could there be added an option to make it fully transparent? The background of the widget, i mean. And only display the text and the dot and whatever else!
Thank you kindly!

Hi, didn't search the thread, sorry.


I had Ampere installed on my old phone, got a new Huawei P30 Pro International and tried to download from Google Play. GA shows that "Ampere is Unsupported on this device". So I tried to download via apk mirror and Ampere is working flawless. Whats the problem with GA Store?

Hello,

Same here.

Worked good on a previous p20pro, and tried to install a few weeks ago and same message on p30pro.

Hope it could be fixed.

Why is the app displaying the value above 3A. My charger is the original Xiaomi QC3 adapter that outputs 5v3a, 9v2a, 12v1.5a. Is this a detection error as I tested with two chargers and two cables.

With my P20 Pro I had no issues at all..
With P40 Pro if I connect the P20 Pro charger (5v 5a) it shows correct Amperes.
With the P40 pro charger, that has 3 voltages I just get 10 mA

Love this app, I have used the pro version for years. Recently I lost my phone and I'm now using an old Samsung S5 Neo running Android 10 on Lineageos 17. Playstore claims the app is not compatible with my device, but I then tried installing it from apkpure and the app itself works fine.

It's just playstore that thinks its incompatible.

Problem is I think without the playstore install it won't unlock the pro version right?

The accuracy is off with about 300mA, my USB Amp meter says the phone is charging with 1,2A and Ampere says 1500mA

Probably not - But you could try contacting the Dev & provide them with your GPA proof of purchase - Maybe they can help you with the Pro unlock?

What does this mean? Is this bypass charging (current drawn directly from AC mains) at work? In the OS battery is shown as fully charged but the charging LED is lit up and the flash symbol that signifies charging is there.

Using an ext. USB Power Tester current drawn varies between 300-600mA with the device in use. Resistance between 9-13Ohms. If testing is done in CPU Throttling app current drawn jumps to 1.2-1.4A and ress. falls to 4Ohms.
P.S. I have manually limited max. charging current to 1.6A and max. charging voltage to 4.2V. Previously when set to 4.1V and max. battery charge was set to 75% it was very DIFFERENT.

    Ampere current meter for pre Lollipop devices

    Please read first the original thread.

    Pre Lollipop devices (up to Android 4.4.x) do not have a common standard interface to read the battery charging current. On some devices the current value can be read from the kernel and on other devices the current can not be determined at all.

    If the app works on your device, please report it in this thread, so I can add them to the list of working devices.

    If the app doesn't work on your device, please read the second post and try to give some useful info, so the app can maybe enhanced to support also your device.

    Debug info
    If your device only shows 0mA all the time or other absurd value then you can long-push the battery button to get a debug info toast about the used interface (only pre Lollipop versions).

    Beta tester community
    You can join the Ampere beta testing community on G+ and you can become a tester to get the beta releases (if there is any) automatic on Google Play.

    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.) If the app doesn't support your device, you can collect some info to help.

    --------------
    PLEASE read this first:
    http://forum.xda-developers.com/showpost.php?p=64432305&postcount=164
    -------------

    1.) You need adb installed

    2.) Pull a list of your /sys/class and /sys/devices directories
    Code: 
    adb shell ls -alR /sys/class/ > files
adb shell ls -alR /sys/devices/ >> files

    3.) Search for current_now or batt_current or BatteryAverageCurrent or power_now and look for the whole path (the interfaces currently used in the app are listed in point C)
    Code: 
    grep -B20 -i <searched_word> files
## example:
grep -B20 -i current_now files

    4.) Try it out. Reading the file gives the current, if lucky.
    Code: 
    adb shell cat <your whole path>
## example:
adb shell cat /sys/class/power_supply/Battery/current_now

    If it gives a value which can be considered as the current (between 0 and 500 in case of a normal USB 2.0 port), then read out the value more times and look if it changes or not.

    5.) If you think, you found your device's interface file to read the current, then please report it in this thread, with the Model string and other device info together.

    B.) If your device seems to be supported (no error dialog), but the measured current values are wrong or 0 all the time.

    You can report this in this forum. You can switch on a debug info bubble (toast) in pre Lollipp devices (Android 4.0.3-4.4.4) by just long-pushing the battery button in the app, make a screenshot and insert the screen shot in your post.

    The debug bubble shows the following:
    • The first line is a device info line
    • List of all available interfaces (path) including the multiplier (a number which is used to scale the row values got from the interface) and the app internal entry number.
    • The firs interface in the list is the for measurement used one
    • The debug bubble is also shown, if no interface is found
    There are devices with mA interface ( value 10 = 10 mA) and there are devices with uA interface ( value 10000 = 10 000 uA which is 10 mA). The multiplier is used to get the mA value. In the mentioned first case it is 1.0 and in the second case it is 0.001.

    Try to find out what is wrong. The multiplier is wrong, or the used interface is wrong. In the second case, please search for a correct interface (point A).

    C.) The list of currently scanned file interfaces:

    New way to get your device supported

    If you want to help, please do the followings:
    1. Please install the latest Ampere
    2. Start the System Info screen: Touch 6 times the Build version in Settings/About Ampere
    3. Without leaving the System Info please share the outputs with me. The easiest way is to save (share) to Drive/DropBox or somewhere others one by one. Later you can put the files from there in your post as attachment.
    4. The test cases:
    • No charging -> push refresh -> share
    • USB charging -> push refresh -> share
    • AC charging -> push refresh -> share
    • Wireless charging -> push refresh -> share
    • Fast/Quick charging -> push refresh -> share
    Please do not forget to rename the files or to give a proper description (No Charging, USB charging,...) by sharing

    Ampere v1.56
    Ampere v1.56 has been published on Google Play (and also in the first post of this thread).

    Changes
    • Alert ringtone chooser added (Settings / Alert settings)
    • Max. USB current detection added (Settings / Basic settings)
    • New measurement interfaces added
    • Bug fixes

    USB-C cable checking with Ampere
    If you have an USB-C device and you want to know, if your USB-C cable is an USB-C spec compliant cable, you can do it with Ampere. Here is the description how to do it.

    Note
    On Nexus devices is the measurement interface in Marshmallow (Android 6) unfortunately not working (always 0 mA). This is a firmware bug. Please use the "Old measurement method" which is still fully functional also in Android 6.
