That’s about right. I parked around 8pm. No wonder I feel my battery ran out so fast. I didn’t pay close attention to it until recently.
I was expecting to charge it once a week since I don’t drive too much, so far have been charging my car 2-3 times a week. Not lazy-friendly 
This is one of the biggest mistakes potential tesla owners make, in my personal opinion. I personally am not a huge fan of owning one of these cars without either home or work charging (as in, charging where you live, or spend 8 hours working at).
People without home or work charging tend to think some variation of " Oh, I am buying a car with 300 miles range, I only drive 20 miles a day, so I should be able to charge every 10 days or so and have some spare left over" and it absolutely, positively does...no...work at all like that.
Lets use a model Y that has "326 Miles
EPA range". EPA range bolded for a reason.
No one is going to drive from 100-0. Its recommended to charge on a regular basis to no more than 90%, and most people are not going to go much below 20% on an EV.
90% of 326 is 293.4 (lets call it 294)
20% of 326 is 65.2 (lets call it 66)
So, right off the bat, a "326 EPA range" model Y has an actual effective range of 294-66, or 228 miles of range.
This does not take into account that the EPA range can only be achieved if one drives like the EPA tests (just like a gas vehicle). On average, if a commute above is 20 real world miles, that commute will take between 20 and 35 miles off the range meter, depending on weather, speed driven, etc.
None of this takes into account energy used while not driving, like sentry mode, or taking lunch in your car and watching netflix or disney plus, etc etc
So the above fictional person, who has a 20 mile commute but no home charging, and who expects "Oh my tesla goes 326 miles, my commute is only 20 miles a day, so 10 days of usage should be 200 miles, so this will be a piece of cake", is in for a rude awaking.
What will actually happen for this person is their 20 mile commute will likely use 30 miles of range on average, and they dont have "326 milees" they have 228 miles, or 7 days ish before their car is at 20% or lower.
Its also VERY common for someone who doesnt have home charging to also want to use sentry mode (because if they had a garage they likely could plug in at home), so there goes another 12-20 miles a night of usage they were not expecting. Call that, conservatively, 15 miles a night, and now the car is using 30 miles driving + 15 miles a night, or 45 miles a day, for a "I need to refill the battery" time of 5 days, when they were expecting on a conservative basis to do it every 10 days and have plenty left over.
Change the math for whatever your actual commute is. If you were expecting 7 days, its probably more like 3.
When I see people ask in the model 3 subform "should I buy this car if I dont have home charging" I usually say "only if you have some reason other than convenience for buying the car".
Home charging (or work) changes all of that, because it simply doesnt matter how much power you use then, because you dont go anywhere to "fill up". That 20 miles a day driven uses 30 miles a day, but so what, its not even noticed.
I am just laying out the "real world" usage for "not charging at home", and how many miles people use. This is not a "tesla" issue, really, its an "EPA range" issue and the fact that people look at the miles and forget that they are not going from 100-0.
my case is more flexible I guess. I totally agree with you, I wouldn’t consider buying EV if I don’t have home charge. Charging during work would be ideal but home charge is essential for me.
