Hello Jah, great question! You can get up to 13 hours of battery life when you are on the go with a case that doubles as a wireless charger. One full charge provides up to six hours of play time and the charging case provides up to an additional seven hours. Running low on power but in a rush to get out the door? A quick 15-minute charge in the case will get you up to 1.7 hours of play time. ^Elizabeth
