      Posted .

      Our Onyx Studio 6 has up to 8 hours of battery life. This may vary depending on volume and music content. If the speaker doesn't meet the advertised playtime hours even at low to mid-volume levels, there could be a problem with the battery of the unit. Please contact our Customer Support, so we can assist you. HarmanKardon
