I got a Sena 10S for Christmas of '19. I updated the software when it came out in January 2020. It has been too cold and rainy to use it much, but each time I have a window to go riding it is dead. I have fully charged my module and left it on the desk near my PC. I leave it in the off condition and not attached to the helmet docking station. How long should it hold a charge? What causes the discharge?
