You can see it drop from milliamps to microamps.

That's not how manufacturing does it.
Their installed and at the end of assembly line, full power is applied.
They either work or they don't.

I remember when part of my job was fixing power supplies. Some that
failed the automatic part of the test last thing on one day would work
the day after.

I never found out why that happened but I assumed it was an
electrolytic so I changed the lot.
