METHOD FOR CHARGING AN ENERGY STORE, MOBILE DEVICE AND CHARGING DEVICE

A method charges an energy storage unit of a mobile device, in particular a hearing aid, which is alternately able to be charged in charging phases and able to be used in use phases. For the charging in an upcoming charging phase, a probable duration of the upcoming charging phase and a probable energy consumption of a subsequent use phase are determined based on past charging phases and past use phases. A required charge for the energy storage unit is calculated based on the probable energy consumption. A charging schema for charging the energy storage unit is set for the upcoming charging phase based on the required charge and the probable duration. A mobile device and a charging device are also specified.
