I just noticed the one Mavic Pro Platinum RC looses about 10% battery while off after 48 hours in the case! Is this normal? I am charging it again and will check it in 2 days again, I have2 RC units but one is at DJI having a antenna repaired I don’t think that one lost that much battery while off! I don’t know if I have another bad RC out of the box? If so this is ridiculous! I purchased 2 mavic PP drones the first one I opened had a broken antenna so that RC went back now the second has a possible weak battery?
