After prolonged use, my mini soundlink will suddenly just go silent. It is always hooked up to its AC adaptor and at full charge. If I smack it, the sound instantly returns. I believe it to be a bad connection with the battery. If I pull the battery out and replace it, the sound won’t cut out for a while longer. I don’t want to drop the cash on a new battery if it’s the connection between the speaker and the battery that is faulty.
irktgreat this could be any connection. You’ll have to take it apart and check for colder solder joints, cracked connections or lose wires. “if I pull the battery out and replace it, the sound won’t cut out for a while longer.” would not have any change when you “smack” it. This fault does not sound like a battery issue
