Slow boot time charger LiPo

When i connect the MKR WIFI 1010 to USB, the start up time seems to be incredible long.
First the charging LED turns on - blinks for a while (2s already gone...), and then the board starts doing what it should do.

Can i speed up the process somehow? Maybe deactivate the LiPo charger?

What is the charge state of the battery now?
