guys cant get charching measure on my rog 3...always "???"

If the problem still exist after rebooting your device and you would like to help me to figure out what the problem is, you can do the followings:

Please send me the "Ampere's system info" of your device in the following charging states (in Email and not here in this forum. For my email address please look in the Google Play.):
  1. not charging
  2. charging with a computer's USB socket
  3. charging with original charger
  4. charging with some third party charger
You can open the Ampere's system info in the following way:
  1. Put an Ampere widget on your home screen (doesn't matter if you have the pro version or not)
  2. Open "Settings" in Ampere
  3. Open "About Ampere"
  4. Click "Build Version" 6 times
  5. Wait a few (about 10) seconds and push the refresh button
  6. Share the output with me in email (with the share icon and as text in an email)
Please reboot your device before you start!

Questions

Hello,
I have a question. Why can i not see the Charging speed, Max USB Current?
The i would like to know if it would be possible to show the charging Voltage (especially interesting with all the different fast charge options). Or the charging Power in W.
And last question is if i am doing something wrong. I have seen pics where the max temp was displayed. But i can only find the actual temp. Would be nice to see how hot the battery (max temp) gets during for example a wireless charging session. Or when using a app that causes a heavy load on the Devices CPU/GPU.

You can use 3c Battery Manager which keeps a detailed record of battery temps., charging voltage and current.

Is there a way to remove the amp reading on the right hand side of the notification? It always forces the third field of "additional information" to be truncated.. (see pic)

This time it was not possible to attach the APK (xda-developers changed something) so you can download the latest APK from here.

Changes
  • Preparations for Android 12

Those values (Charging speed, Max USB Current) are read from your device and if your device doesn't support them, then they are not available.

The "max temp" feature is an interesting idea. Nobody requested it until now...

Hello

Been using Ampere back then in 2016 for a while, and now get the PRO version. But is there any plans to implement some battery data logging? Im curious about some battery usage on my phone. Just a simple csv maybe enough.
Thanks in advance.

This would be an amazing add on especially to see prolonged battery usage and how much it affects health of the battery

Is there any difference between the Google Play Store app & "...or you can download the lates APK from here." app in the original post? Do they both include "Contains Ads & Offers in-app purchases"? Thank you.

It looks like the Play Store Version got an update end of April 2022 (v. 3.53), while the one on Google Drive is from October 2021 (v. 3.50). Regarding Ads/In-App purchases, I would assume they both are the same.

    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.

    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.

    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.

    Hi @nihil0 what do you think about adding a charging history where you can see the the percent of the battery next to the time and used mA.
    That way the user could see in what intervall der battery was charged...maybe with a function for the user to reset or save that current history.

    Thank you!

    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
