If your Beoplay Eleven are connected to your device, the battery will drain. So, to conserve power, always place the earphones in the charging case to switch them off completely when not in use.
Moreover, Beoplay Eleven have a power saving function which is turned on by default and can be turned off in the Bang & Olufsen app. To turn the power saving function off, enter the product page in the Bang & Olufsen app and simply disable the option “automatic standby".
When "automatic standby" is enabled, Beoplay Eleven will automatically switch off after 15 minutes of being removed from the ears.
