&lt;p&gt;Most of these peripherals are dependent on the EasyDMA structure which itself will consume about 1.3 mA. What you measure is therefore not unsurprising. I would just disable the peripherals after I&amp;#39;m done using them before going to sleep to save power.&lt;/p&gt;
&lt;p&gt;regards&lt;/p&gt;
