    i bought my model 3 in aug 2018. After the software upgrade I only got 316 miles when charged to 100%. Last night I got only 312 miles from 5% SOC to 100%. A 4% degradation within 10 months? Have others degraded similarly?

    you say you got 312 miles charging from between 5% to 100% SOC? As written, that would mean your total range = 328 miles.

    Or if you meant that when you got to 100% SOC the car showed 312, the difference from your post-firmware range increase is only 4 miles, which is about a 1% degradation. Not everyone saw their range increase to the full 325mi after the firmware update. I'd even wager that most people did not. So I would not use 325 in your calcs unless you actually witnessed your car charging to that amount after the update.

    Same here. I’ve had my LR RWD 3 w 19in Sport wheel since April 2018 and seen the initial 3% range degradation (yielding appr. 300 total range ) earlier this year. Then, a software update when Tesla announced the 325 LR 3 increased my total range from 300 to 315.

    The most recent update 2019.20.4.2 update that included Beach Buggy reduced it to 310 compared to the 315 I was getting with version 2019.20.2.1.

    Doubt this is Range degradation but Tesla discontinuing the 325 mile LR model 3 altogether.

    Thoughts?

    Exactly so. My car has never reported more than 315 EPA miles. There is a small variation in batteries from the factory <<shrug>>

    Here’s some data that I’ve recorded since I purchased the car starting with 20 miles.
    Currently have 2600 miles (probably not enough miles to reflect any loss of range)

    1. Max range at 100% SOC 314
    2. Min range at 100% SOC 302
    3. Average 307.5

    This data is all from the iOS stats app.

    Right. More like range appreciation.

    LR RWD
    15k odometer
    80% 258 = ~322 @100%
    90% 289 = ~321 @100%

    I'm happy so far as I believe the BMS range is just a best guess and not to be considered absolute. Many things, outside temp, wind, terrain, can affect the "full" range you will get on any particular trip.

    Wow some ppl in this forum are worse than Apple fanboys. The OP was just asking about range and how others have been effected and you hit him with disagrees and saying he should be appreciative it's more miles than he purchased it....but that's not the point. Tesla put out a press release that he should have either 325 or 315 miles now, depending on model, that's the advertised range now.

    People have to understand that the range is determined by EPA not Tesla, and it is performed under a specific driving criteria. Not real world driving conditions. Gasoline engines are rated by EPA as well. If you can find me any vehicle that matches the MPG they promise please let me know because I have not seen one yet, and gasoline cars are not even close to their EPA rating.

    10,000 miles. I have charged to 100% about 5 times.

    Normally routine is to drain the battery to around 15% and charge to 90%. About one charge every 3-4 days. I do not follow the plug it in all the time rule.

    I think I’m doing quite well.

    My April 2018 build had 321 when the update happened with approx.18k miles, I now have 27k and have seen it as low as 304 and then adjust up to almost 310 recently, currently shows 308, I have had the battery down to 20% and charged to 90% a couple of times and it seemed to help with reported range adjustments, I will be road tripping soon and we will see if there are any changes then, I tend to arrive at Superchargers with less than 10% on this route when stopping at Harris Ranch and when I eat I charge to 100% as long as there is very light usage there so maybe reported range will change after this?

    My July 2018 3LR charges to 300-302 @ 100%. Tesla service center says there are no issues.

    I’ve read that the first year has the biggest degradation and then it degrades more slowly. I think 4-5% is average and then 1-2% in the following years but we still won’t know for awhile.

    methinks i get 312 miles @ 100% battery charge with 25,000 mles or 41,000 km
    but for this scientific random sample, I will charge to 100% tonight for an accurate measurement

    My LR Tesla 3 with 25,944 miles or 42,000 kilometres
    314 miles or 509 km @ 100% range

    This represents 3.4% range loss for approximately 26,000 miles

    Went to 524 once after the update and now hovering around 500km estimated at 100%. Just under 5% degradation after one year if we go with the latest charge estimate of 501.06 :)

    I noticed that after updating to 2019.32 my M3 doesn't fully charge any longer! I always charge to 80% ~248 miles and before 2019.32 it would charge to about 250 miles. After it was always charging to 242. So I charged to 100% and it will only go to 295 Miles. I did it twice as a test and both times 100% charge is 295 miles. Anyone else have this experience?
