I reset SC to factory settings. I have noticed that I can no longer change the time until the batteries discharge themselves. When the drone is off, this option is visible in the SC, but cannot be changed, and when the drone is turned on, there is no option in the menu
the drone needs to be on for the discharge time to be set and will need to be done for each battery in turn try clicking on details and see if the discharge settings comes up
You must upgrade DJI GO4 to version 4.3.25. If you reset to factory setting you have the release 4.3.16 that has not this option. You need to download the release 4.3.25 directly from DJI as .apk and then copy on SC and launch it
