Battery drains when unit is turned off
I have two sena 20s that both have the same problem. When the unit is fully charged and powered off, after a few days it will be dead. I never had this problem with the smh10.
Question: would it be OK to leave it plugged into a usb charger all the time? That way when I want to go riding i can just grab it. Otherwise I have to remember hours before I ride to charge it. Or I end up riding with a USB cable plugged into the unit on my helmet.
Has anyone else had this problem? I am using 1.3 firmware and serial number is 14100xxxx
Sena please let me know if it is OK to leave it plugged in all the time.
Other than that, it is an excellent headset.
