Abstract:
1. A method of detecting whether a battery in an electronic device is counterfeit or defective, the method comprising: determining one or more specified conditions for operating the battery on the electronic device; generating, by the electronic device and based on the one or more specified conditions, at least an electrical load; applying, by the electronic device, the electrical load to the battery, the electrical load changing one or more electrical characteristics of the battery; generating, on the electronic device, an actual battery characteristic profile by recording performance of the battery during use of the battery while the electrical load being applied; retrieving from a memory element, an expected battery characteristic profile defining parameters expected when a legitimate battery operates under specified conditions corresponding to the electrical load, the memory element storing a plurality of expected battery characteristic profiles each corresponding to different conditions; comparing the expected battery characteristic profile with the actual battery characteristic profile to determine a value representing an error between the expected battery characteristic profile and said actual battery characteristic profile; and taking a responsive action on the electronic device when the value exceeds an error threshold.
