https://devzone.nordicsemi.com/f/nordic-q-a/91378/issues-with-52832-sleep-currentHi， The product is used in a humid environment, found that the 52832 chip sleep current becomes large, from 30uA to 80uA, now has disconnected all external pins only retain the most basic peripheral circuit, the situation is still the same.

It would be interesting to see if the increased current is due to the humidity or if there are solder issues.&nbsp;</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/383544?ContentTypeID=1Sat, 27 Aug 2022 05:58:37 GMT137ad170-7792-4731-bb38-c0d22fbe4515:a69c496f-f68f-4051-abe4-4e1c6cdebc19xiaoQ911<p>Put the product into 85 temperature and 85 humidity test chamber, the probability of producing leakage is 50%</p><div style="clear:both;"></div>https://devzone.nordicsemi.com/thread/383452?ContentTypeID=1Fri, 26 Aug 2022 11:42:04 GMT137ad170-7792-4731-bb38-c0d22fbe4515:818540b3-86ac-4e49-8556-50b0c345a314ketiljo<p>If you see this in only one device, I suspect solder problems, corrosion etc. In very humid environments, some kind of conformal coating is recommended.</p><div style="clear:both;"></div>
