10mph headwind in Oklahoma? Haha, unlikely.Picked up a new '21 NCA SR+. Just wanted to check if this is normal range for around 80mph avg (give or take) highway use? This is on a 350 mile return trip home. Temperature is shown is about representative and heat was in use. If you extrapolate this out it is around 147 miles range for 100% to 0% battery. Someone elsewhere said this is abnormal. Sorry for no pick of the energy usage screen. Winds were relatively light but it's possible it might have been at most a 10mph headwind.
Wait, what happened there moderator? Where’s the poll gone?Hello everyone
I can’t find a good source of data on range loss over time for our Model 3’s. Just lots of discussion. So let’s have a poll of model 3s on this forum!
I’ve looked and can’t find a thread like this on the Model 3 forum. But excuse me if I’m wrong.
To help provide some consistency in how we all reply, I’d suggest we disregard the range that Tesla quote. ie: EPA, WLTP etc.
Let’s use the difference between the most miles you’ve ever shown on a full charge and the current displayed 100% charge.
So for me in my 9-month old MIC M3 with the LG Chem E5D battery:
My max range is currently showing 336 miles.
The max range ever shown was 344 miles from new.
So I calculate the range lost as 2.3% at 5000 miles.
So what’s your total range lost from the maximum ever shown?
i realise this isn’t scientific as it’s impossible to make the poll on this basic website that asks age, miles and range, but hey let’s just put some data on the Tesla forum and see what happens!
So tell us, how’s your Model 3 range holding up?

To be clear to those reading the thread, this result appears to be highly unusual. No other reports of zero loss (or even close) that I am aware of.3yr old LR-AWD
Max range currently showing: 311miles
Max range ever: 310miles, it's all within the rounding error.
Range lost: 0% at 27,000 miles
The advice you are going to receive is that 10% after 2 years is within the range of reasonable loss. In addition, the rate of degradation is higher in the first year and is likely to slow. You should not charge to 100% regularly. As for typical charging, the advice you will hear is that higher SOC at higher temps will increase degradation. So depending on your climate, you could consider lowering your daily SOC or at least using the feature that doesn't charge until you are ready to leave. The closer to 50% SOC the slower your degradation will be. You will need to find a balance between your daily SOC needs, your desire for max performance and your desire to limit degradation. Alternatively, you can just forget about it and keep doing what you are doing because your battery is fine.My battery has around 10% degradation after 2 years and 18k miles.
The car shows 282 miles if I were to charge to 100%, AND scanmytesla also shows 10% degradation.
If the battery already lost 10% capacity, then shouldn't we be able to charge it up to 100% and have that effectively be the same as when charging to 90% on a new battery?
I have used supercharger very rarely.
I always kept my daily charging at 90% or below.
Since there is less acceleration below 50% SOC, with the degradation and charging to 90% after degradation, I only have 40% of battery to use before acceleration is diminished.
If it's advised to normally charge no more than 90%, does it make any sense to increase that if battery capacity is already diminished?
When it will be 25% down to 232 miles max charge, we still would have to charge to 209 to stay within 90% daily soc??
Minor edit - but as data from @AAKEE has posted, if you want to minimize the rate of capacity loss (looking primarily at SOC), your maximum SOC should be limited to 55% or lower. Some additional cycling losses will happen if you go below 20% SOC, but overall for storage purposes since your typical car sits around 95%+ of the time, the lower your average SOC, the better.The closer to 50% SOC the slower your degradation will be.

While I don’t have the data for KenC’s usage, and environment I would say that it would be possible to get away with a very small degradation.To be clear to those reading the thread, this result appears to be highly unusual. No other reports of zero loss (or even close) that I am aware of.
If you want to try to duplicate it, store your car in Maine and charge it to 60% fairly consistently. Occasional road trips and Supercharging are allowed. (You will almost certainly not duplicate it.)
Yes I have mentioned that before here - it may be less than a couple %.As the 77.8kWh pack is known to reach a initial capacity above 78kWh( ?) and the degradion threshold is about 76(?), it would be very possible to stay above that threshold for quite long.
Yes, I agree with you based on your data. My point was that a battery cycling life test from say 10-50% rather than 25-50% will produce deeper cycles and usually result in faster capacity loss. But once you've already cycled the battery (say you discharged more than normal), there's really no reason to rush to recharge, and in fact you're better off letting it sit at low SOC as long as possible before recharging.Actually the research test data tell us that the lower the SOC, the lower the calendar aging will be.
And the smaller the cycles is, the lower the cyclic aging is.
Also the lower the cycles is positioned in the SOC span the lower the cyclic aging is.
Theres no increased degradation in capacity for cycling below 20%. Actually, if cycled between 20 and 10% the battery almost lives forever.
I havent tried using 50% SOC so I havent seen the difference from my regular 55% when it comes to the BMS capacity calculations.
I have stopped looking at my battery range since I moved from SR RWD 3 to LR AWD Y. I just kept in percentage and I’m having trouble using more than 10% a day. I don’t know if it’s the heat pump, long range or both but this LR is fabulousIn one month time with colder temps my battery went from 291 to 284 at 100%. 2020 LR
You are overthinking it.From the recent posts, it seems like taking delivery in Winter is best for the battery as it will be parked at low ambient temperatures. I take delivery of a M3P in about two weeks (EDD in signature.)
Armed with this info, this Winter I plan to:
* Keep the car in my unheated garage (stays around 40°F/5°C in winter)
* Keep the charge limit around 50% SoC
* Not charge over 50% except immediately before driving when I will need the range (my electricity is not on a TOU plan)
During the remainder of the first year:
* Get an air conditioning unit large enough to keep the garage cool in Summer, preferably no higher than 75°F/24°C
* Continue keeping the “sleep” SoC low as above
* Try to keep the total mileage under 5000mi/8000km in the first year (this might be harder than expected)
* Minimal or no Supercharging
Since the first year or so is crucial in terms of calendar aging, I want to avoid the frequently-reported 10% capacity loss after the first year.
Questions:
Is there anything else I should plan to do in the first year to minimize the early degradation?
Does anyone know the SoC the packs are charged to before being put on trucks/trains/ships for delivery to sales/pickup centers?
Is there any way to request a lowered SoC percentage at pickup? I’d rather them not charge past 70% if possible. The last two (used) cars I have bought from Tesla were charged to 100% SoC, and had probably sat at that charge level for days.
