1. A method comprising:sensing, by a temperature sensor, a temperature of a first portion of a device during a charging process of a rechargeable power source of the device;
determining, by processing circuitry and based on the temperature of the first portion of the device and an algorithm, a temperature of a second portion of the device,
wherein the first portion is not thermally coupled to the second portion of the device, and
wherein the algorithm is representative of an estimated temperature differential between the first portion and the second portion, the estimated temperature differential determined based on a transfer function, and wherein the transfer function is based on an electrical parameter measured from an electrical component associated with the charging process, and
controlling, by the processing circuitry, the charging process of the rechargeable power source of the device based on the determined temperature of the second portion of the device.

Samsung Electronics Co., ...

1. An electronic device comprising:a housing;
a display;
a battery mounted within the housing;
a power interface mounted to a part of the housing or disposed within the housing, and configured to receive power from an external power source wirelessly or through a wire;
first charging circuitry;
second charging circuitry;
at least one sensor;
control circuitry; and
at least one processor, wherein the at least one processor is configured to control the display to display a screen capable of selecting a first mode among a plurality of modes in response to a user input,
wherein the control circuitry is configured to:
in response to selecting the first mode, supply, via the first charging circuitry, a first part of a current supplied from the power interface to the battery, supply, via the first charging circuitry, a second part of the current to at least one electronic element included in the electronic device, and supply, via the second charging circuitry, a third part of the current to the battery, and
control the second charging circuitry to block the third part of the current not to be supplied to the battery based on detecting heat generated in a part of the battery by the at least one sensor,
wherein the second charging circuitry is connected to the battery in parallel to the first charging circuitry,
wherein the first part of the current and the third part of the current are supplied to the battery simultaneously,
wherein the plurality of modes includes the first mode, a second mode, a third mode, and a fourth mode, and
wherein the first mode is a mode in which both the first charging circuitry and the second charging circuitry are driven, the second mode is a mode in which only the second charging circuitry is driven, the third mode is a mode in which only the first charging circuitry is driven, and the fourth mode is a mode in which the first charging circuitry is driven and the second charging circuitry is selectively driven.
