Just came back from holidays, thought I'd share the results. Can managed to fit a surprising amount of our luggage. 3 big suit cases + 2 little suitcases + 3 small backpacks all in boot/frunk with UMC and Type2 Left it on the 17th with 60%, valet mode on, sentry mode off Came back on 29th with 53% It was losing charge mostly to waking up ~ every 24 hours or so to do something. The 24+ hours sleep sessions only cost 0.1-0.2 KWh, it's when it wakes up for 3 hours it uses 0.3. Longest sleep session was just over 48 hours. The manual states to expect 1% a day, Mine averaged about 0.5% a day so can't complain.
