Power management features

One or more non-transitory computer readable storage media encoded with instructions that, when executed by a processor of a medical device, cause the processor to:

• determine a current charge level of a power supply configured to provide power to the medical device, wherein the medical device is configured to operate in at least one of first and second modes to deliver stimulation to a recipient of the medical device, wherein the medical device has different power consumptions in each of the first and second modes;
• obtain input associated with operation of the medical device;
• while the medical device operates in the first mode, determine, based on the input and the current charge level of the power supply, an estimated remaining operation time period during which the medical device is likely to continue to operate in the first mode before switching to operation in the second mode;
• and
• determine, based on the estimated remaining time period during which the medical device is likely to continue to operate in the first mode before switching to operation in the second mode, an estimated power supply life for operating the medical device according to the second mode with a second set of configuration settings at an end of the estimated remaining operation time of the medical device in the first mode.
