Just an alert for all users have just upgraded to latest DJI Vision App for P2V my battery indicator on Ipone app showed 96% but when I landed it was actually 4% I was flying for about 20 minutes today and was wondering why I hadn't heard the familiar claxon horn alerting me battery was getting flat. The app showed me that I still had 96% battery left. Not trusting that the new app had improved energy efficiency that much I flew the P2V back to look how many lights were displaying on battery and to my shock saw only 1 light illuminated. I quickly landed and then after the P2V was shutdown the app then showed 4%. I had constant streaming for the full flight but it appears there was a glitch with battery data. This is the first time i have had this issue and with 20 odd flights with old app never had this. This flight was only the second with new app upgrade so I hope it isn't the flavour of things to come.
