Abstract: Certain aspects of the present disclosure relate to techniques and apparatus for optimizing long term evolution (LTE) connected discontinuous reception (CDRX) for single radio hybrid tune away devices. Certain aspects provide a method for wireless communications by a user equipment (UE). The method generally includes entering a DRX mode wherein the UE alternates between an activity period and an inactivity period while connected to a first radio access technology (RAT) network, tuning away from the first RAT network for a tune away period to monitor signals in a second RAT network, determining when an inactivity timer for the DRX mode expires or will expire, and adjusting a value of the inactivity timer based, at least in part, on the determination.
