The method includes receiving data including a charge level of a battery of the protective case, identifying a charge level of a battery of the electronic device, and generating a graphical representation. The graphical representation includes an indication of the charge level of the protective case battery and an indication of a charge level of the electronic device battery. The method further includes displaying the graphical representation on a display of the electronic device. ## Claims ### Claim 1 A method of power management for an electronic device having a computer processor and a battery, the electronic device being communicatively coupled to a protective case for the electronic device, the method comprising: receiving, from the protective case, data including a charge level of a battery of the protective case; identifying a charge level of a battery of the electronic device; generating, using the computer processor, a graphical representation that includes an indication of the charge level of the protective case battery and includes an indication of a charge level of the electronic device battery; and displaying, on a display of the electronic device, the graphical representation. ### Claim 2 (depends on 1) The method of claim 1 wherein: the received data further includes a mode of the protective case; and the graphical representation further includes an indication of the mode of the protective case. ### Claim 3 (depends on 2) The method of claim 2 wherein the mode of the protective case indicates whether the protective case is receiving power from an external power source. ### Claim 4 (depends on 2) The method of claim 2 wherein the mode of the protective case indicates whether the protective case battery is presently being charged. ### Claim 5 (depends on 1) The method of claim 1 wherein the graphical representation further includes an indication of a charging status of the electronic device battery. ### Claim 6 (depends on 1) The method of claim 1 further comprising transmitting, to electronic circuitry of the protective case, the charge level of the electronic device battery. ### Claim 7 (depends on 1) The method of claim 1 wherein the graphical representation further includes an indication of a percentage charge remaining for each of the protective case battery and the electronic device battery. ### Claim 8 (depends on 1) The method of claim 1 further comprising: gathering operational information of the electronic device; and transmitting the gathered operational information of the electronic device to the protective case. ### Claim 9 (depends on 1) The method of claim 1 further comprising: receiving, from a user of the electronic device via the electronic device, power management preferences; and transmitting the power management preferences to the protective case. ### Claim 10 (depends on 1) The method of claim 1 further comprising calculating, using the computer processor, a power remaining metric, wherein the power remaining metric is based on the charge level of the protective case battery and the charge level of the electronic device battery. ### Claim 11 (depends on 10) The method of claim 10 further comprising: calculating, using the computer processor, an estimated amount of operational time remaining for the electronic device based on the power remaining metric; and calculating, using the computer processor, an estimated shutdown time for the electronic device based on the estimated amount of operation time remaining and a current time. ### Claim 12 (depends on 11) The method of claim 11 wherein the graphical representation further includes one or more of the estimated amount of operational time remaining and the estimated shutdown time. ### Claim 13 (depends on 1) The method of claim 1 further comprising: receiving a request from the protective case via the electronic device; and transmitting the request to a transceiver of the electronic device for delivery over a network to a server. ### Claim 14 (depends on 13) The method of claim 13 further comprising: receiving a response from the server via the electronic device; and transmitting the response to the protective case. ### Claim 15 (depends on 14) The method of claim 14 wherein the request from the protective case is a request for a firmware update for the protective case and the response from the server includes the firmware update. ### Claim 16 (depends on 14) The method of claim 14 wherein: transmitting the request includes transmitting historical power usage information associated with the electronic device; and the response includes a recommended operational profile that is based on the historical power usage information. ### Claim 17 (depends on 13) The method of claim 13 wherein: the electronic device is a cellular phone, a smartphone, or a tablet computer; the transceiver is a wireless transceiver; and the network is a wireless network. ### Claim 18 A method of installing a power management tool in an electronic device having a computer processor, the method comprising: receiving, at the electronic device, an indication that a protective case has been operatively connected to the electronic device; receiving, at the electronic device from the protective case, a software application comprising the power management tool; storing the software application in the electronic device; and executing, by the computer processor, the software application to manage power available from a battery of the electronic device and available from a battery of the protective case. ### Claim 19 A method of installing battery management software in an electronic device having a computer processor, the method comprising: receiving an identifier associated with the battery management software from a case communicatively coupled to the electronic device; transmitting, using network communication capabilities of the electronic device, a request for the battery management software to a server over a network, wherein the request includes the identifier; receiving the battery management software from the server in response to the request; and installing the battery management software on the electronic device. ### Claim 20 (depends on 17) The method of claim 17 wherein the identifier is a uniform resource locator (URL) and the server is a web server.
