Hello Adam,

Correct - using slave latency will allow the peripheral to skip a connection event (or multiple) if it does not have any new data to transmit, which will reduce your over all power consumption by reducing the number of empty packets being sent in order to maintain the link.

If you are certain that there always will be data ready for transfer when a connection event is upcoming then the peripheral will always transfer in these events, and so there will be no impact of enabling slave latency. In this case the slave latency would indeed be redundant.
In this case your best bet would be to increase the connection interval as much as possible, in order to decrease power consumption by the radio.
Having slave latency enabled does not cost any additional power, so if there is a chance that you will not have data to send for some time, then it would be beneficial to enable slave latency.

Best regards,
Karl
