You can use the Tessie app without without waking up the car.I understand this and intentionally open the app to wake it up. Loosing some SoC is not a big deal for me.
2) keep the main battery charged around 50%-60% is best for its longevity while it's in storage
Generally lower state-of-charge (but not below 0%) is better in terms of avoiding battery degradation over time. For NCA batteries, it is best to minimize time over 55%. For LFP batteries, it is best to minimize time over 70%, although it may matter less than with NCA batteries.keep the main battery charged around 50%-60% is best for its longevity while it's in storage
I also have a Model 3 RWD with the LFP battery. I've had the car a little over 1 year and its my first EV so I'm still learning. I tend to over analyze things, but I think your strategy looks good to me.I believe the important part is to really understand what's good for the main battery when it's in storage for sometimes.
My understanding are:
1) do not let the main battery goes down to 0% as it will also stop charging the LV battery. If the LV battery is dead, you cannot even open its door, trunk, etc....
2) keep the main battery charged around 50%-60% is best for its longevity while it's in storage
3) charge it to 100% for the BMS to re calibrate for accurate assessment of battery SoC before one resumes driving the car.
With these understandings:
1) I will leave home with SoC around 50% or higher (whatever SoC is at that time).
2) Set charge limit to 50%, leave the car plugged in. Charging may NEVER happen if SoC did not go below 50% limit during vacation.
3) A day before going home, set charge limit to 100% to get full charge and BMS calibration.
The Long Range (and Performance) has another battery.Um, I have a 2022 M3 LR. This is the first I'm hearing about needing to charge to 100% on a weekly (or other regular basis). I was told by the agent who did our sale that we should charge only to 80%. Have I been doing it wrong?
It's the M3 RWD (with LFP battery) that Tesla recommends charging to 100% at least weekly. Your car's charge screen will show the recommended daily charge level.Um, I have a 2022 M3 LR.

If you are not using it, there is no need to charge it to 100% every week. Just keep it at 50% and charge it to 100% when you get back. You are overthinking this.I have read lot of information about this topic related to model Y.
My question is specific to 2023 M3 which Tesla recommends to fully charge to 100% once a week.
My car will be in the garage for 3 weeks during my vacation (fully charged before I go on vacation).
I have seen it loosing 1% per week on a previous 2 weeks out of town.
Three weeks would cause the battery to lose 3%. Not a big deal I guess,
This time, I will leave it plugged in, schedule it to charge to 80%., starting at midnight (for lowest electricity rate, in California).
My guess charging will never happen as the SoC would be close to 100% , way above 80%.
On my 11-th day of vacation, I will schedule it to charge to 100% to comply with the recommendation.
I will set a security camera pointing to the Wall Connector so I can watch the light showing charging in progress (for my own curiosity and entertainment).
I know this is unnecessary as the APP shows that too. It would be fun to see that as If I am at home.
Please let me know if there is anything wrong with this plan.
That's exactly what I did when going on vacation.Just keep it at 50% and charge it to 100% when you get back. You are overthinking this.
