Samsung patents phone battery saving by switching off secondary radio

Patent drawing
Patent drawing from the official filing.

Samsung describes a method for devices with two separate radio chips to save battery power. The system keeps the secondary radio in a low-power 'connected' state to handle quick data transfers, then switches it to an 'idle' state once the data is sent or a power-saving trigger is activated.

Why it mattersThis filing focuses on optimizing how phones manage their internal hardware to extend battery life during light usage.

In the filing’s own words

A method for managing a radio access in a user equipment (UE) having a first radio and a second radio are provided. The method includes initiating, by the UE, an operation in a low-power radio resource control connected state for enabling at least one of uplink communication or downlink communication using an optimized radio resource by the second radio f the UE, and transitioning, by the UE, the second radio into a low-power radio resource control (RRC) idle state during at least one of upon completion of a data transmission or triggering of a power saving condition.

What exactly they claim (claim 1)

1. A method performed by a user equipment (UE) having a first radio and a second radio for managing a radio access, the method comprising: initiating an operation in a low-power radio resource control connected state for enabling at least one of uplink communication or downlink communication using an optimized radio resource by the second radio of the UE; and transitioning the second radio into a low-power radio resource control (RRC) idle state during at least one of upon completion of a data transmission or triggering of a power saving condition.
