A client brought his soundlogic bluetooth speaker for repair, as per him the speaker was charging full within few minutes and it was shutting off after around five minutes, i informed him the battery might have failed or gone bad, he gave me a non working portable fan and asked me to use battery from fan if possible. This video shows solution for above mentioned problem.
Take care and do the reparation on your own risk.
Thank you for watching, have a GOODTIME.
