ELECTRONIC DEVICE CASE
First Claim
1. A protective case for an electronic device, the protective case comprising:
- a rechargeable battery;
an interface for connecting to the rechargeable battery;
a group of display elements;
a device interface for electrically interfacing with the electronic device;
an external interface; and
electrical circuitry configured to;
receive electrical power from an external power source through the external interface;
determine a charge state of the rechargeable battery;
exchange communications with the electronic device through the device interface to determine a charge state of a rechargeable battery of the electronic device based on information received in the communications;
allocate a portion of the received electrical power to the electronic device, a magnitude of the portion based on the determined charge state of the rechargeable battery of the protective case and based on the determined charge state of the rechargeable battery of the electronic device;
supply the allocated portion of the received electrical power to the electronic device through the device interface if a condition is satisfied; and
supply a remaining portion of the received electrical power to the rechargeable battery of the protective case.

20. A non-transitory computer-readable medium including computer-executable instructions that, when executed by one or more computer processors of a case for an electronic device, direct the one or more computer processors to:
-
receive electrical power from an external power source through a power interface of the case; receive a communication from the electronic device through a device interface of the case; determine a device charging current for a rechargeable battery of the electronic device based on information included in the communication; determine a case charging current based on the device charging current; supply the device charging current to the electronic device through the device interface; supply the case charging current to a battery associated with the case; receive a subsequent communication from the electronic device after a period of time; and adjust the device charging current and the case charging current based on the information from the subsequent communication.
