'Telephone call' CSLI indicates the 'approximate physical location . . . of a cellular telephone only when a telephone call is made or received by that telephone.' ...By contrast, 'registration' CSLI 'provides the approximate physical location of a cellular telephone every seven seconds unless the telephone is 'powered off,' regardless of whether any telephone call is made to or from the telephone.'
