At full volume, it works for about 2 hours, then the speaker turns off at 40% charge, notifying you of a low battery. This is fine? I found the time and tested it at a volume of 80%, it works for more than 6 hours. The only charge less than 40% does not show, apparently this is a defect in the column firmware. We can assume that 40% is 0%.
