+Most iOS devices come equipped with a variety of sensors that measure motion, orientation, and various environmental conditions.
+Additionally, these devices include advanced sensors such as the image sensor (commonly referred to as the Camera) and the geo-positioning sensor (commonly referred to as GPS).
+
+The common point of all these sensors is that they are power-intensive while in use. A typical issue arises when these sensors continue to process data unnecessarily after the application enters an idle state, like when it is backgrounded or the user stops interacting with it.
+
+    As a result, calls to manage these sensors must be carefully paired: `AVCaptureSession.startRunning()` and `AVCaptureSession.stopRunning()`.
+    Failure to properly manage these calls can lead to significant battery drain within a few hours.
