Why am I stuck on the battery calibration screen?

This is due to your phone's firmware not including the ability to provide information about battery current through normal means (BatteryManager API). In your current situation you can press the back button to forcibly quit the tutorial, you'll get a warning message that you can just confirm. The app will then work but everything related to battery current and drain will be unavailable and be set to 0.

We will look into a workaround for devices that do not implement this and we've already added support for some reported devices so please send us an email if you are stuck on the calibration screen.

The following are devices confirmed to have issues and are currently unsupported:

-Galaxy S5 Neo

-Galaxy S5

-Galaxy Note 3

-Galaxy A3

-Galaxy S4

We'll be changing our Play Store settings so that users with these devices won't be able to download AccuBattery.

*It's possible the above phones and other non-supported models will work with custom ROMs running Android 5.0+ if the phone has the ability to provide the info but the software doesn't. If you are running a custom ROM you can download the latest AccuBattery apk files here and install the app manually: https://drive.google.com/drive/folders/0B6_KD4Gw5zlRZTJPSHY2bGMwQVU

Other known issues:

LG G3 shows current multiplied by 10x. A future release will include a toggle to fix this.

HTC m8 seems to show 0 or negative numbers for charging current when charging, if this is actually working correctly on your m8 please contact us.

Some more obscure Chinese devices will see negative estimated capacity, this leads to messed up calculations or nothing being shown in the health tab. A future release should be able to take care of this.
