Yesterday I made a flight and when I returned I had about 25% battery left, and I kept the drone in a closet with the battery in place. And today in the morning I heard the sound in the distance when the drone was turned on, I went to the closet to check and indeed, the equipment was turned on. The equipment is completely new, I have only taken a couple of flights, and the app marks everything in order with the battery. I would like to know if someone has happened something similar

Hello there aalejaandro. I am sorry for the trouble this has caused and thank you for reaching out. Have you tried to turn off your DJI Mavic 2 Pro properly by pressing the Power button once, then press again, and hold for two seconds to turn the battery off. Thank you.

Try refreshing the firmware with the DJI Assistant,  someone posted here recently with this issue and that fixed if for them.
