Hello. I have been flying my Mavic Pro for about 6 months without crashing or having any problems until recently. My Mavic battery is taking 4 hours to charge, give or take, and has recently reached 68 degrees C (155 F) while in flight. It has 190 cycles and the flight time has degraded to about 17 min at best. Can someone tell me if it’s the battery, what I need to do about it and if there is anything I can do in the future to prevent this problem.
