 I need some help in understanding and optimizing current consumption profile of nRF9160 in LTE-M cellular connection mode. 
 nRF9160 is implemented in custom board and is powered by Lithium Thionyl Chloride battery (3.6 V).

&lt;p&gt;1. if you don&amp;#39;t use PSM, the device will not go to sleep mode. Once you enable it (and the MNO/provider supports it), your current should go down to 400&amp;micro;A.&lt;/p&gt;
&lt;p&gt;2. If the UART is not suspended, the RX sampling drains that 400&amp;micro;A. Suspend the UART or disable it in the device tree and you will be down to 4&amp;micro;A.&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
