Classification: CPC G | IPC G

Claim 14:
15. A device for estimating ambient temperature of the device, the device comprising:
a neural network processor including a classifier neural network, wherein the neural network processor is configured to:
monitor a plurality of parameters comprising a battery temperature of a battery of the device, processor, thermal zones, voltage, current, instantaneous Central Processing Unit (CPU) load, average CPU load, Graphics Processing Unit (GPU) usage, and screen brightness;
monitor a plurality of external parameters comprising lux, Wireless-Fidelity (Wi-Fi) signal strength, and network signal strength;
determining, by a regression neural network in the device, a temperature representing a result of subtraction of the ambient temperature of the device from the battery temperature, based on the plurality of parameters and the plurality of external parameters;
determining, by the device, the ambient temperature of the device based on the determined temperature and the battery temperature;
determine whether a cause of overheating of the device is due to one of internal factors and external factors;
classify the cause of overheating of the device due to the internal factors when the battery temperature is greater than the ambient temperature of the device; and
classify the cause of overheating of the device due to the external factors, when the battery temperature is less than the ambient temperature of the device.
