Abstract: Some aspects of this disclosure relate to apparatuses and methods for implementing cell search based on battery conditions of a user equipment (UE). For example, some aspects of this disclosure relate to a UE. The UE includes a transceiver configured to enable wireless communication with a base station and a processor communicatively coupled to the transceiver. The processor is configured to perform a cell search cycle in response to a determination that a connection with the base station has been lost. In response to a determination that UE is in a no-service mode or in a limited-service mode after the cell search cycle, the processor further configures a sleep timer value based at least on one of a charge level of a battery of the UE or a capacity level of the battery. The processor further performs a second cell search cycle after the configured sleep timer value.

Abstract: The present application relates to devices and components including apparatus, systems, and methods for IMS registration in wireless networks.
