Battery degradation??

I have a 2022 Model Y Performance (Feb )
When it’s charged at 100 % it’s supposed to show around 300 miles , it was hovering around 298-300 which was okay. Now after 6 months it’s showing around 280-293 miles . I opened a case with Tesla and they remotely checked and said it’s because I was using when I was driving and was going above 65 , etc. while I agree the batter consumption varies according to the usage when I am charging the car at night that number should be consistently close to 300 when I charge to 100%. I don’t charge to 100% everyday, only when I go on a long trip. Normally I charge to 70% since my day trips are close to ~50-55 miles .

Now my question is , is thus battery degradation ? Is this rate of degradation normal ? Is there anything I can do to fix this ?
 
I have similar concerns, and my indicated degradation is significantly worse than the 5% / 1% mentioned in the note above. I got my Y in May of 2021 - when new the nominal and indicated range at 100% was about 330, which matched the specs. Now, my indicated max range at 100% is about 293, a reduction of 11.2%, and the car age is 1.33 years. The rate of apparent degradation has not decreased at all. I've tried the rebalancing tricks as noted in other threads, but they don't seem to have any effect. At this rate, I will have lost 30% of apparent capacity when the car is 3.5 years old. I say "apparent capacity" because no one but Tesla really knows what the capacity is. I only SuperCharge on long trips; home charge to about 80% otherwise, and have put about 30,000 miles on my Y. I also have a lifetime Wh/m of 242 which is the nominal value Tesla uses for the EPA calculation and shows that I don't really drive in an excessively spirited manner.

Lots of threads and discussion on this. I'll save you the search.

5% for the first year of ownership and 1% each year afterward.

It's a little more than that. Maybe 7% in the first year and 2% per year for another year or two, then reducing to 1%, although it's still too early to tell how the trend will continue. It seems to be mostly age-related as opposed to charging practices, although that does play some role.

stop worrying so much, it is meaningless anyway that number. Your numbers will always fluctuate. Just enjoy the car and drive.

5% for the first year of ownership and 1% each year afterward.

From the extensive (and I do mean extensive) discussions on this exact topic in the model 3 subforum, I would say its more like "5-10% the first year, trending down after that at about 1 ish percent a year or so".
 
Telsa diagnosed the battery of my 2022 M3 (Feb 2022) with 8,000 total miles. The retention capacity is only 86.7%:mad:. 0% supercharger.
I think Tesla should look at your Y to get a better understanding why this is happening. They can't say that 13.3% capacity loss in 7 months and 8,000 miles is normal. Understanding why it is happening is essential to preventing it from happening to other Teslas. There must be some uncommon mechanism at work. Toyota called such failures "golden gifts" because they provided opportunities to improve their knowledge and thus their manufacturing and design reliability. Having outliers like this show that they don't have control of their manufacturing process.

2021 MYP. 303 miles estimated when new. 18 months of ownership/10,500 miles. Zero supercharging/Always charge at home on a 240 line. Drive roughly 150 miles/week. Charge twice a week to <80%. Only charge to 90%+ when I take a longer trip(Rarely).

After charging to 90% this past weekend I did the math and am at 277 miles at 100%.

Not really worried about it as I set it at percentage all of the time. Makes me wonder what will happen in another year or so though.
 
I’ve done almost the opposite of what’s recommended (not all by choice) on my LR 21 MY. My battery has been at 0% for 3 months after an accident, I charge to 100% a few times a month, I have to supercharge 3-6x a month and with 14,500 miles I show 323 miles at 100% obviously it’s an estimate but surprised I’m not showing more degradation with my battery habits.

it will level out, my 2021 MYLR w/ 20" wheels has 23k miles and been sitting at 7% degradation for 7 months, you'll be okay
