I hope with the last update, it would fix the battery problem on the 50S. I have return the first unit for a replacement. I still have a crap battery, will not last longer then 3 hours or so. Even if I only turn on music and not run the mesh. I feel like they either need to fix it it, or we sue Sena for false advertising. The app shows 100% battery life, 12 hours. Once I play music, you can watch it drop down to 10 hours withing 10 minutes. It can't play 1 song without going down 5% on the battery life. I about to go on a 10 day ride, I'm going to run a USB cord from the bike into the sena unit on my helmet.
