A method performed by an electronic controller includes determining a charge level of a power supply configured to provide power to a medical device, and estimating, based on the charge level of the power supply, a first power supply life for operating the medical device according to a first mode. Further, the method includes estimating, based on the charge level of the power supply, a second power supply life for operating the medical device according to a second mode. As recited, operating the medical device according to the first mode has a different power use or consumption characteristic from operating the medical device according to the second mode. The method also includes generating a notification indicative of the first power supply life and the second power supply life.

A device and method for improving hearing devices by using computer recognition of words and substituting either computer generated words or pre-recorded words in streaming conversation received from a distant speaker. The system may operate in multiple modes such as a first mode being amplification and conditioning of the voice sounds; a second mode having said microphone pickup up the voice sounds from a speaker, a processor configured to convert voice sounds to discrete words corresponding to words spoken by said speaker, generating a synthesized voice speaking said words and outputting said synthesized voice to said sound reproducing element, which is hearable by the user. Other modes include translation of foreign languages into a user's ear and using a heads up display to project the text version of words which the computer had deciphered or translated. The system may be triggered by eye moment, spoken command, hand movement or similar.

A system may obtain data related to hearing instruments, such as data indicating answers of a user to a questionnaire or historical usage data of the hearing instruments. For each respective feature of one or more features, the system may determine a feature duty cycle corresponding to an amount of time during a period in which the respective feature is anticipated to be active based on the data related to the hearing instruments. The system may further determine an energy cost for the respective feature at least based on the respective feature duty cycle for the respective feature and a power consumption rate of the respective feature. The system may calculate a battery life of one or more batteries in the hearing instruments at least based on the energy costs for each feature of the one or more features.

A method is indicated for operating a hearing aid, wherein the hearing aid is switchable between a usage state, in which a signal processing unit of the hearing aid is activated, and an idle state, in which the signal processing unit is deactivated. The hearing aid has a time measuring unit, which has a first timer and a second timer. The first timer is activated in the usage state and is deactivated in the idle state, for time measurement during the usage state. The second timer is activated in the idle state for time measurement during the idle state. Furthermore, a corresponding hearing aid is indicated.
