Forgive the newbie question but I can’t find a post addressing my issue. I have an air 2s. My batteries are self discharging quicker than is expected. In a couple of days I’m seeing from 100% down to 85ish%. Surely that’s not right. I’ve seen one video where you can get into the battery settings and adjust the number of days before the battery starts self discharging. Can’t find that menu on my bird. ??
