we use the LattePanda 2G/32GB (Windows 10 Activated)
with an external RTC Battery. 3V /CR2032 Cell
Now we have a problem with the Battery life.
The power consumption is too high wenn the Systems/ Win run .

We measured:

LP off I=2,5uA that's OK Lifetime several years.
LP ON I=150uA way to high. calculated lifetime 3 months!!

Do you know the problem? Is there a solution?
