good day i have my ueboom 3 megaboom now about 1 month and am not really satisfied already after a very short time i noticed that the battery of 20H does not hold with me like before i charged the ue boom to 100% and then listened to music for 2.5H music before it went out and also told me batterly low please charge and then it went out i think this might be a broken one? and yes i have always charged it to 100% over 3H charging time!
