my camera(camera2 api) eats so much from battery and device is being hot after 5 minutes running. During trying to find out where is the problem, i saw that onCaptureCompleted method of CameraCaptureSession.CaptureCallback is being called continuously when preview is in running state. Is it normal ?

If you call setRepeatingRequest() then it is normal to get multiple call in onCaptureCompleted(). If you want a single shot you can replace setRepeatingRequest() with capture() .
And the number of time onCaptureCompleted() called is depend on things like capture request's template type.
