ESP32D0WD deep sleep current

[PaulShaw]

hi,there
I set ESP32 into deep sleep,it's current is 10uA.
But it slowly increases to 50uA or more.It takes several senconds or minutes.
After I replaced ESP32,it's deep current is kept at 10uA.

When I replaced the old one,the current increased slowly.

What‘s the reason?

Thanks in advance for your help!
