Embodiments of apparatus, packages, computer-implemented methods, systems, devices, and computer-readable media are described herein for a mobile computing device with a primary processing unit configured to operate in a normal mode and a reduced power mode. The mobile computing device may include a secondary processing unit, coupled with the primary processing unit, configured to provide, to a remote computing server, location data of the mobile computing device. The secondary processing unit may be configured to receive, from the remote computing server, one or more POIs contained within a geofence, identified based on the provided location data. The providing and receiving may be performed on behalf of the primary processing unit while the primary processing unit is in the reduced power mode. Operation of the secondary power processing unit may require less power than operation of the primary processing unit in the normal mode.
