The play times vary depending on the heating zones you are using (upper body/chest zones and/or the hand pockets/gloves zone) along with which heat setting you are using. The play times will decrease faster when you turn on more zones and adjust the heat level settings higher. Also, charging your phone and heating the jacket at the same time will also decrease battery life faster. Lastly, when outside temperatures drop and is low, it will also affect the length of heating times and performance of the battery.
Below is the link to the heating time chart according to our Ravean Curved Black 10050mAh battery that is currently for sale on our website.
