I recommend that you go into the menus and make sure you turn the software off when not using it. Don't let it turn Bluetooth on unless you are using it right then. Turn off the wifi connection as it will try to find the camera continuously. Drained my battery from 100% to 10% in half an hour. Doing the above fixed this.
This software is really terrible as well, nothing but limitations. We need to get Nikon to provide true professional support for this camera. Such as in the following;
Unstitched Raw still export.
Unstitched Raw video export.
Unlimited time lapse settings for both interval and total duration.
True Exposure settings.
Remote power on & off either by cable or Bluetooth/WIFI.
And that is just the beginning!
I'm astonished that Nikon brought this to market with this software at this price point. They should be ashamed.
