Systems and methods for power management of a mobile electronic device. During operation of a modular mobile electronic device, module power characteristic data of a plurality of modules coupled to the electronic device is collected. Each module is coupled to the electronic device via a respective module interface of the electronic device. A module power model is updated for at least one module of the plurality of modules based on module power characteristic data collected for the at least one module. A context-aware power budget of the electronic device is updated based on updating of the module power model for the at least one module. Module power flow of the electronic device is adapted based on updates to the context-aware power budget. Adapting module power flow includes adapting allocation of power in real-time to at least one power consumer module coupled the electronic device via a respective module interface.
