The battery level obtained from Stripe M2 connectedReader.getBatteryLevel() is incorrect.

Summary

The battery level obtained from Stripe M2 connectedReader.getBatteryLevel() is incorrect. Our application actively queries the battery level of the M2 device. The result obtained is 60%, but in reality, it is 100%. This continuous prompting for charging has caused some inconvenience to customers.

The log is as follows.

Code to reproduce

Reader connectedReader = Terminal.getInstance().getConnectedReader(); if (connectedReader == null) { return 0; } Float batteryLevelF = connectedReader.getBatteryLevel(); if (batteryLevelF == null) { return 0; } float nowBattery = batteryLevelF * 100;

Android version

Android 9.

Hi @OliverYang0305. Are you able to reproduce this with the latest SDK release?

@bperez-stripe Hi, I tested on version 3.3.0, and the problem still exists. The return value of connectedReader.getBatteryLevel() seems to always be the battery level at the time of connection.

I got same issue like seems to always be the battery level at the time of connection. I have set timer and every 5 mit checking Battery Level code : Terminal.getInstance().connectedReader?.batteryLevel?.times(100) ?: 0.0F Where else I can found Battery Level or How I can refresh Battery Level ?

Hi all! With the release of Terminal SDK 3.6.0, Terminal.connectedReader's battery level will now be updated whenever the mobile reader's battery info is reported.
