Brake wear vs. frequency of charging

[Archimedes]

I am also unaware of Taycans having a true auto-lock feature. There is only a lock if you unlock and do not enter the car.

Pretty sure my car locks itself if I fail to do so and walk away after driving it.

You might be right. I never rely on it as it has the missing visual confirmation of folded mirrors. I’ll check it out and see if it relocks after I enter the car - I thought it did, but I could be mistaken.

I'm starting to wonder about the benefits of plugging it in like I did all my Teslas

All Tesla's suffer from severe phantom power drain (use of battery power when not driving the car).

That's why Tesla owners have been advised "Always Be Charging". When you're charging daily, you don't notice phantom power drain.

I lose between 4% and 7% per day with my Tesla Y while its idle. On my Taycan, I can go for two weeks (as I did recently) and I'll lose maybe 2%.

If you don't charge a Tesla everyday, the phantom power drain can cause a severe loss of range: I go maybe (if I'm lucky and drive modestly) 150 miles from 85% in the Tesla in a week before I drop below 20% and need to find a charger

I don't think it auto locks. Only the door handles retract after some time but you can still open it without the key fob nearby. I've done this many times when going back to the car to grab something without the key fob.

Only time it will auto lock if you approach the car while locked and don't open the presented door handle. It will then retract the door handle and locks.

If there's an option to autolock while walking away, I haven't found it in the PCM.

If you're losing 4-7% a day on your Model Y, turn off Sentry Mode. If you are not using Sentry Mode, take it to service, as there is something wrong with your car. My parents recently drove 60 miles to the airport in their Model Y, left it there for a month, drive it home, no issues. 4%-7% a day would result in 120% loss 210% battery loss, so while I don't know exactly what their SoC was, we can easily conclude the car didn't lose more than 1% a day. I've owned 4 MS over a decade, 1% a day was usually the most the car would lose in the first 3 days, then it slows down as long as you don't keep pinging your car with the app. The worst drain I experienced was 3% overnight but that was when I parked the car in 13F weather, in the middle of a very windy field. Adding a 24/7 2ch BV dashcam to my Teslas added to the drain slightly, but no issues. Sentry Mode is a battery suck though, it was one of the reasons I never used it.

As for my Taycan, it hides its vampire drain. When I park it, it keeps showing the same percentage even if I leave it for 2-3 days. Then the vampire drain is just added to the first mile or two of driving (driving the Taycan after 3 days being parked uses more energy per first mile than if I drove it after 1 day).

That's why Tesla owners have been advised "Always Be Charging". When you're charging daily, you don't notice phantom power drain.

Not exactly. They advise to stay plugged in so that the car has an option to use "shore power" instead of cycling the HV battery. For example, when you turn on pre-heat/cool on a Tesla which is plugged in, it will use AC connector power to heat or cool the car. Taycan on the other hand will drain its battery, then when the batter reaches some lower threshold, it will charge it back - unnecessary discharge/charge cycle, which add to battery wear and potentially has you leaving with lower than desired state of charge.

If you don't charge a Tesla everyday, the phantom power drain can cause a severe loss of range: I go maybe (if I'm lucky and drive modestly) 150 miles from 85% in the Tesla in a week before I drop below 20% and need to find a charger

Ok, so you do 150 miles from 85% to 20%, so 65% of the battery. Given the rated range of the MY is 303miles, that would mean you used at least 50% to drive 150 miles. You actually used more since it was multiple trips (your average is 21 miles a day) plus Tesla 303 miles is in ideal conditions. But even if you by some miracle achieved the rated range (I never managed to in a decade of diving Teslas), then the remaining 15% was lost over 7 days, so less than 2% a day. Again, considering you are probably not achieving rated range, that means your car likely lost ~1% or less a day, not 4%-7%. Do the math yourself.

and again I cannot follow. Taycans (I'd say any BEV despite Teslas) have no vompire drain.
Vampire drain is due to Tesla's trade off to keep the car in connected standby, whereas "normal" BEVs are shutting off the HV battery and only wake up to check the 12V battery every few days.
You can park your non-Tesla for a month with 50% SoC and will drive home with 49-50%.

Sentry mode is off. With sentry mode ON, I lose 7%. With Sentry mode off, I lose around 4% (I need to check this on multiple days due to rounding). I screen shot state-of-charge when I leave my car so I know what I have lost due to phantom power drain.

If you are not using Sentry Mode, take it to service, as there is something wrong with your car.

Obviously you haven't read this:
Tesla created team to cancel service appointments, report says - Los Angeles Times (latimes.com)

I've brought the Y in for service due to what I believed was poor range and was told there is nothing wrong with the car.

Do the math yourself.

I've done the math: phantom drain over 7 days at 4% per day is 28%. This week I charged Sunday night with 125 miles used and I had 22% left. 125 / .63 = 198 mile range extrapolated to 100%. Adding back the loss due to 7 day phantom drain: 28% * 275 miles = 77 miles. Therefore 275 miles max range at 100% with no phantom drain. Once again, the range is 275 miles if you drive this in one day. But if you commute to work as I do, phantom power drain causes 28% charge lost in a week.

BTW when I take the Y to the airport, if I turn off the Telsa app on my iPhone power drain drops to less than 1% (when you close the app, Tesla displays a message "Keep the Tesla app running for the best phone key experience"). Sure, you can reduce phantom power drain, but all Tesla's suffer from this unless you take steps to prevent it. Steps which are not 'normal'.

I need to grab some actual data, but essentially I noticed that if I leave the car for 2-3 days, the very first 3 miles uses about 4% of the battery (SoC drops from 85% to 81%). However, if I charged it recently, the drop in SoC is much smaller. I do this drive regularly, hence I notice the difference is SoC drop. Next time I don't drive the car for 2-3 days, I will note down exact numbers. I should also check the reported consumption to see if it aligns with SoC percentage drop and miles driven.
