The real-time screen doesn't show the value levels


  • After I charged the battery and connected via Bluetooth app the real-time screen doesn't show the value levels anymore. 
    Is there anything that I'm doing wrong or should do differently? 



  • 1) Is your Bluetooth connection to other apps or is there any other battery app installed in your phone? because the data saved on the phone in the two apps are in conflict, the original data cache needs to be cleared every time you start.

    2) Another reason, the battery may be charged to the protection state, so the app can not show the data. you can discharge the battery for a while and then connect the app will be no problem.
