Thank you for sharing your feedback. You are correct, our JBL Charge Essential has up to 20 hours of battery life. However, this may vary depending on volume and music content. If the earbuds don't meet the advertised playtime hours, even at low to mid-volume levels, and after hearing less bass-heavy music, there could be a problem with the battery of the speaker. For further assistance, you may contact us at (800) 336-4525 Mon - Fri: 9:00 am - 11:00 pm (EST) Sat - Sun: 9:00 am - 5:00 pm (EST)
