1. An eyewear device that provides augmented reality services, the eyewear device comprising:
a frame configured to be worn on a head of a user;
a camera system supported by the frame, the camera system comprising a first camera and a second camera;
a display system supported by the frame;
a temperature sensor supported by the frame, the temperature sensor configured to detect a temperature of the eyewear device; and
electronics supported by the frame, the electronics coupled to the camera system, the display system, and the temperature sensor, the electronics having at least two power configuration modes and comprising a processing system configured to:
run application services of the eyewear device, at least one of the application services configured to use at least one of the camera system or the display system;
monitor the temperature of the temperature sensor;
compare the monitored temperature to a threshold temperature;
notify the at least one application service of an upcoming change from a first of the at least two power configuration modes to a second of the at least two power configuration modes responsive to the monitored temperature reaching the threshold temperature; and
change the electronics from the first power configuration mode to the second power configuration mode after notifying the at least one application service;
wherein the at least one application service includes a first operating state and a second operating state, the at least one application service changes from the first operating state to the second operating state responsive to the notifying of the upcoming change, the electronics includes a graphical processing unit (GPU) coupled to the display system, the at least one application service is a rendering service configured to render images with the GPU, the first operating state renders images at a first frame rate. and the second operating state renders images at a second frame rate.
