Problem with the battery or charger
Recently i attended an auction an purchased the black and grey ue boom 2 with white volume buttons. I got home and charged it for around 2 hours and proceeded to turn it on. When checking the battery by similtanously pressing the buttons it said 100% but not even a minute later it turned off with the message battery critically low please charge. Now ive used diffrent chargers that worked with my other speakers ( eliminating the cable for source of error) however when charging i belive a white LED should activate leading me to belive the error in the port but i am unsure wether the problem lies within the port or the battery itself.
Thank you all answers can help!
