I am currently using the CMMovementDisorderManager to query tremor. Currently, The tremor is being calculated ~every 5 minutes, however for my use case I was hoping to get Tremor ~every 1 minute. I understand that the Manager "To preserve battery life, the manager doesn’t perform calculations in real time. Instead, it periodically and opportunistically analyzes the raw data, saving the results on the user’s device". However I am wondering if there are ways to optimize the device or certain permissions I can enable to ensure that I am giving the manager the greatest 'opportunity' to analyze the raw data.
There's no supported way for you to have more control over the way CMMovementDisorderManager performs calculations with the APIs currently available.
