vampire drains

Hi - would like to have an idea on vampire drains. I parked my cars for the past 3 days and the average power drain was about 6.6km / day. I did wake the car a 2-3 times a day via android app. As HK is relatively small, I safely may asusme tempreature difference is minimal. Mind to share yours? Thx

Thanks Dennis. That is about 4.8km/day and with no app-interaction. My loss seemed still in acceptable range. By the way, I forgaot to state the initial condition: my car had initial range of 334km (209mi). Not sure the loss is linear or has flattening slope later on.
