UE Boom 4, Poor battery life
I bought the Boom 4 to replace my over 10 year old UE Boom which started having battery issues. The Boom 4 feels cheaper then my original, it has far less battery life, with the battery only lasting for 1 to 1.5hrs when volume on 80% or above which nearly doesn't cover one home workout session. It is no where near as loud as my old one so volume has to be high hence destroying battery life. It also takes far too long to charge especially when considering how long you get from that charge. Almost have to use the speaker when plugged in and constantly on charge. Overall am not happy with the Boom 4 and will look at returning for another brand.
