Samsung patents phone cooling that swaps signal boosters to prevent overheating

This filing describes a method for electronic devices to manage heat during wireless communication. When a temperature sensor detects that the device is getting too hot, the system stops one active connection and switches to a different power amplifier to reduce heat generation.

Why it mattersThis is a routine hardware optimization that helps keep phones cool during heavy data usage, which is a common concern for users with hot devices.

In the filing’s own words

An electronic device is provided. The electronic device includes a temperature sensor, multiple power amplifiers, memory, comprising one or more storage media, storing instructions, and at least one processor communicatively coupled to the temperature sensor, the multiple power amplifiers and the memory, wherein the instructions, when executed by the at least one processor individually or collectively, cause the electronic device to perform first communication by using a first power amplifier among the multiple power amplifiers, perform second communication by using a second power amplifier among the multiple power amplifiers, identify a temperature of the electronic device by using the temperature sensor while performing the first communication and the second communication, in response to a situation in which the temperature of the electronic device exceeds a first predetermined threshold temperature, release the second communication, and switch a power amplifier which is to perform the first communication.

What exactly they claim (claim 1)

1. An electronic device comprising: a temperature sensor; multiple power amplifiers; memory, comprising one or more storage media, storing instructions; and at least one processor communicatively coupled to the temperature sensor, the multiple power amplifiers, and the memory, wherein the instructions that, when executed by the at least one processor individually or collectively, further cause the electronic device to: perform first communication by using a first power amplifier among the multiple power amplifiers, perform second communication by using a second power amplifier among the multiple power amplifiers, identify a temperature of the electronic device by using the temperature sensor while performing the first communication and the second communication, in response to a situation in which the temperature of the electronic device exceeds a first predetermined threshold temperature, release the second communication, and switch a power amplifier which is to perform the first communication.
