The one way I know of to check the battery status of the remote controller is by looking at the four white lights on the top of the controller.  

I was wondering if the DJI GO 4 app displays the remote controller battery status anywhere on the screen of the phone or tablet?  The only battery status I see on the screen is for the drone.  I am using the Android version of the app.  

Thanks.  

Hello and good day. Thank you for the inquiry. The DJI Go 4 application does not show the battery status of the remote controller. The DJI Mavic Air remote controller battery status is shown on the 4 led light ( each led light lit is approximately 25% of the battery charge). If you have any other concerns or inquiry. Please feel free to post it here at DJI Forum. We are here to help you. Thank you.

It's no problem on Mavic Pro it's on the screen of the controller.

Thank you for the replies.  I figured it did not display on the app but I just wanted to make sure and did not miss something with all the information it does display.  The lights should be good enough.

Just scroll down the Aircraft Status on your DJI GO 4 App. Hope you can find it

Thanks for the information.  I was able to find it in the status area.  Interesting that it is not on the primary view screen.  Maybe DJI is concerned the pilot may think it is for the drone battery and unknowingly get caught with a dead battery on the drone.  It is good to know it is there if I want something more precise than the lights.

Aircraft Status bar where you guys check the firmware errors and calibration

My DJI smart controller only has two flashing white lights. It will not charge above 40%. Is there a way to reset the controller to resolve this? Or is this a battery issue?
