Claim One:
1. An implantable medical device, comprising: a battery; a battery monitoring circuit coupled to the battery, the battery monitoring circuit configured to measure a battery parameter indicative of an energy level of the battery; a neural stimulation circuit configured to deliver neural stimulation for modulating neural activities; a cardiac stimulation circuit configured to deliver cardiac stimulation including one or more of cardiac pacing or defibrillation; and a control circuit coupled to the battery monitoring circuit, the neural stimulation circuit, and the cardiac stimulation circuit, the control circuit configured to: set a current power mode of the implantable medical device to a first predetermined reduced-power operation mode of a plurality of predetermined power modes in response to the battery parameter indicating that the energy level of the battery has fallen below a first energy level threshold; reduce a power consumption required for delivering the neural stimulation without reducing a power consumption required for delivering the cardiac stimulation during the first predetermined reduced-power operation mode; set a current power mode of the implantable medical device to a second predetermined reduced-power operation mode of the plurality of predetermined power modes in response to the battery parameter indicating that the energy level of the battery has fallen below a second energy level threshold; and reduce the power consumption required for delivering the neural stimulation and the power consumption required for delivering the cardiac stimulation during the second predetermined reduced-power operation mode.
