Switch 2: Rest Mode Heating Alert with Cable

User reports of the Nintendo Switch 2 indicate overheating issues when the console remains in sleep mode with an active network connection. The cause lies in a specific setting that keeps the device partially active, resulting in excessive power consumption and potential long-term damage to the hardware.

This issue may impact the device's lifespan. Nintendo has not officially commented on the problem yet.

The setting in question is "Keep wired connection in sleep mode," found in the "Console settings," under the "Sleep mode" section. When activated, it allows the console to continue downloading even while in sleep mode. However, it is this functionality that seems to be causing the heating and unnecessary battery consumption.

To mitigate the risk of overheating and power drain, the recommendation is to disable this option. This will pause background downloads, but will ensure that the console does not operate in a state of "semi-activity" that could lead to issues. As reported on June 22, 2025, the user community has been emphasizing the importance of this deactivation.

It is expected that Nintendo will provide a software update that allows for the continuation of downloads in sleep mode without the inconvenience of overheating. Until an official solution is implemented, disabling the wired connection setting during sleep mode is the preventive measure.

Do you believe that Nintendo should prioritize an update to address the overheating issue of the Switch 2 in sleep mode, or other launch issues may take precedence?
