In case someone else still googles this issue: This happened to my old charge 3 while it was in my bag during heavy rain. Opened it, and found dampness under the rubber that seals the buttons. Drying it all with a cloth and hairdryer fixed this issue. Also lights indicating charge went dark. Think they died permanently. Edit: after drying the circuit with lights, even they function now. Edit2: The whole speaker had to be opened completely. Did remove the battery, but not the motherboard and ports. Did open them all tho, and used a small towel and hairdryer to circuits and insides, since there was drops of water everywhere. Left the whole thing open for a few days. Put the rubber buttons in a sealed bag, as it has a glue surface. Today, put the whole thing back together and it's working like there never was any issue to begin with. Probably spoiled water seals with this, then again, they weren't really good to begin with apparently.
