The product specification says ION_RAMON_RTC is 1.5 μA. What are the circumstances under which this power state is achieved?

If you have started activity and want to enter low power mode again you should stop the activity (e.g. STOP task of uart, twi transfer etc.).</p> <p>Enabling or configuring a peripheral does not cause any current by itself.</p> <p>You may also find this useful:<br /><a href="https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf52-online-power-profiler">https://devzone.nordicsemi.com/nordic/nordic-blog/b/blog/posts/nrf52-online-power-profiler</a></p> <p>Best regards,<br />Kenneth</p><div style="clear:both;"></div>
