It will take maybe a week before it drops. I leave mine in the charger but not plugged in. Mine have discharged but I can’t provide a time line. It’s good they discharge. Sometimes I use the batteries to charge other devices if I’m not flying much.
Hope everyone who wants one gets one. I settled for an Air 3s and am enjoying that. Pricing will be interesting to see if the possibility of lost US sales will increase pricing for other countries.
