Hi, I want to use a speaker in the wilderness for a long period of time and thought that if I could get a speaker where the bluetooth functionality could be turned off I could save power. The UE Boom 2, and the JBL Charge 3 are both great speakers, but you can only disconnect a device, and not turn off the bluetooth completely, i.e. the speaker will constantly still search be searching for new devices, using power. I can't seem to find this info anywhere online, and the guys at BestBuy are certainly unable to help! Any tips would be great, thanks!
