Abstract: An apparatus for estimating a condition of a battery includes a mode identifying unit configured to identify a usage mode of the battery during a period of time and its corresponding attenuation curve, according to recorded data on battery usage, stored usage modes of the battery and attenuation curves corresponding to the various usage modes, the attenuation curve representing a change of a fully charged capacity of the battery with battery usage; and a condition estimating unit configured to calculate battery degradation according to the recorded data, the identified usage mode and its corresponding attenuation curve, the degradation representing a quantity of the fully charged capacity of the battery that is reduced over the battery usage. The condition of the battery is estimated so as to rationally judge the residual value of the battery in operation.

Abstract: Systems and methods are provided for managing navigation among applications installed on an electronic device. According to certain aspects, an electronic device receives (1502) a selection of a graphical item displayed by a source application and an instruction to copy the graphical item. The electronic device stores (1514) an identification of the source application in a data record and navigates (1522) to a destination application. Further, the electronic device receives (1538) a command to paste the graphical item within the destination application and return to the source application, examines (1560) the data record to identify the source application, and automatically navigates (1570) to the source application.
