I got a new/refresh RC from DJI. I have thought all along the battery on the RC does not last very long. I've had many Mavic 2 Pro's and RC's so I have an idea how long they last but not certain. I had charged my RC to 100 percent. I took it out and flew 1 full battery in 75 degrees no wind conditions. I suppose I was in the air like 20 or 25 minutes before I had to land. The RC from 1 battery was down to 83 percent. Can anybody tell me what they think and if this is normal. I don't think it is and I wanted to ask. Thanks, Tom
