First Claim
1. A protective enclosure for a smartphone having an internal battery, the protective enclosure comprising:
- a hard shell comprising a front shell formed to a rigid shape of a front portion of the smartphone and a back shell formed to a rigid shape of a rear portion of the smartphone, the hard shell having an external electrical connector for electrically interfacing to an external device and having an internal electrical connector for electrically interfacing to an electrical connector of the smartphone when the smartphone is inserted into the protective enclosure;
a stretchable cushion layer disposed over the hard shell, wherein the stretchable cushion layer has sufficient elasticity to conform to the hard shell and provide cushioning to the protective enclosure;
a rechargeable battery disposed in the protective enclosure; and
electrical circuitry disposed in the protective enclosure and configured to;
determine a charge state of the rechargeable battery of the protective enclosure;
receive electronic data communications from the smartphone through the electrical connector of the smartphone and through the internal electrical connector of the hard shell, the electronic data communications including information indicating a charge state of the internal battery of the smartphone;
receive electrical power from the external device through the external electrical connector of the hard shell;
allocate a first portion of the received electrical power to the rechargeable battery of the protective enclosure, wherein a magnitude of the first portion is determined based on both the charge state of the internal battery of the smartphone as indicated in the data communications and the determined charge state of the rechargeable battery of the protective enclosure; and
allocate a second portion of the received electrical power to the smartphone, wherein a magnitude of the second portion is determined based on both the charge state of the internal battery of the smartphone as indicated in the data communications and the determined charge state of the rechargeable battery of the protective enclosure.
