Should I be worried?

I have a ‘22 m3awd @ 84%, 55k miles.

That is a concerning level of battery degradation.  If it were a normal battery, I wouldn’t expect more than 5% drop over the next 40000 miles, but I don’t think you have a normal battery.

Just curious about nominal battery reporting vs this full test - when your battery is at 80% how much does the screen shows range in miles? _(If you touch where it says 80%, it flips to miles)_ I know the range shown on screen isn't accurate, just want to know how different is it from the real test If it shows 195 miles at 80% then that implies range is 195/.8 = 243 which is roughly 81% of 303

When I first bought the car at 46k miles, I was getting 205 miles at 80%. Now I get 197 miles at 80%. I never actually charged it 100% till this battery test. But I recall when I first bought it I got 258 miles at 98%. Now at 100% range is 245 miles.

I wonder if these tests are affected much by the outside temperature. Does someone know?

2023 performance, I am at 84% with 44k miles

Only about 1-3% OP's % is crazy ngl

2022 60k km around 37kmiles battery 96% LFP catl

what should you be worried about?

Apparently that the battery retention is within expected range.

and it is. so I'm not sure what is to be worried about

Ok, so 197 miles at 80% means 245 miles at 100% which is 80.7% of original capacity So, the battery test you did agrees almost within 1% point of what the screen shows Good to know (for me) because I don't want the hassle of that actual battery test 👉 Thanks for the info ✅ ---- My 2023 MYLR started as 326 mile range. Now after 40k miles, it shows 177 miles at 60% So full range is 295 and battery capacity is at 295/326 = 90% My daily usage is 20 miles so I keep the battery between 50% and 25% Only for weekends I charge to a bit more. Like it's 60% now But if your daily use is more than 100mile , then keep charging it daily to 80%

When you first bought it, 205 miles at 80% means you got it with 84% battery life, not 92% CarMax lied to you.

“What are the odds we get to below 70% battery healthy before the warranty runs out at 120.” Essentially zero. In fact, I’ve paid pretty close attention to Tesla forums and subs for 10 years now and I can’t recall a single battery replacement for range degradation. Not saying it hasn’t happened, but it’s *exceptionally* rare.

It’s actually quite normal. People post these sorts of test results all the time.

11% to free warranty battery replacement

Mine is at 79% at 115k miles

Anecdotal. I picked up my model 3 3 years ago and the full charge claim was about 264 (from 310). I reset when I took ownership and it went to around ~283 for a few years and recently just went down to ~272. I just did the battery test and it was pretty much spot on with it's 88% which made feel a little silly even doing the test. Probably will go on to recommend only doing the test if things seem odd as it's supposed to help level out the battery packs cells. In short don't take the stated range as being truly what your degradation is.

Mine is 2023 Model Y Long Range bought in March 2023 at Austin. ~115k miles when i ran battery health and it is showing 79%

That's what I wanted to know, how does the nominal display compare to the test. I can't be bothered to actually do that battery test.

Mine leveled off at around 81. I lost like 1 mile of range over the last 30k miles. I am at 90k now on a 21 MY.

The battery test isn’t too bad if you do use when the car is at less than 3% battery, which admittedly is hard to time

How many miles do you get on an 80% charge?

213 miles

I have 2018 42K and have battery at 89%

Is there a difference in real world degradation for long range versus performance models?

How do you find this

this is why buying a used EV is such a gamble.

What typically warrants a battery replacement? I've been struggling with range loss and am now to a point that it's becoming a major inconvenience.

The Battery Health Test on a Tesla Model 3 is located under **Controls > Service > Battery Health Test** on the vehicle's touchscreen, requiring a Wi-Fi or cellular connection to start. This test, which can take up to 24 hours and requires the car to be plugged into a charger, provides a detailed health report.

How much of a range loss?

The warranty is quite clear - measured energy capacity loss exceeding 30% from new. Energy capacity is not the same as range.

my friends dad did this, 19’ model 3

not gonna sugar coat that’s pretty bad. you should track its degradation for sure. 150k 12% lost

21 model y with only 26k miles. Im sitting at 83% on my last test.

Really close to my 22 MYP. 120k miles with 78% retention. Although my "theoretical" miles are closer to 160k if I use Tesla's efficiency rating.

My old 2021 sr+ model 3 with 67k miles at the time I sold it had 79% battery health

I’m so happy i got an LFP car Jesus Christ!

No, it's not.

just for context, i sold my model 3 2019 that i had super charged daily, i had free supercharging promo for 3 years on that car with no home charging. Rip to the person who bought it.

Let's sum it up and maybe things become a little clearer. You have until sometime in 2031 and \~60,000 miles left in the battery warranty. You do not know and probably never will knoiw how the previous owner(s) treated the battery. But mostly none of that matters because Tesla has a very good battery warranty policy and they honor it well. I know because I needed my 2018 Model 3 Performance battery replaced just before I traded it in on a 2026 Model Y performance. My battery suddenly threw a series of messages that it could not charge and to bring it in for service. They replaced the battery and it took two weeks over the Christmas and New Year holidays. I was not aware of the battery warranty until I looked into it. I was mildly surprised to learn that as long as the battery is still in warranty Tesla supplies a loaner vehicle for the duration of the repair. They also replaced my 12V battery and of course changed the coolant fluids. There was an odd significant repair coincidence in that I had a motor replacement on my 2015 Model S right before I traded it in for the 2018 Model 3 Performance. Knowing what I know as a Tesla owner since March 2015 and given my experiences with various repairs I would advise you to not over think your battery health. Drive your 2023 Model Y Performance with confidence and keep charging to 80% and plugging in when you get home. Also pay attention to error messages as they are presented to you. I never felt the need to go into the Service menu and go looking for error messages but you may. I would think of that like getting a lot of proactive health tests that are probably unnecessary if you feel healthy. Sure, you might want as much information as possible and I can't fault you for that but I would also recommend you enjoy your Tesla with as much confidence that Tesla will let you know when there is a problem. One last thing, don't hesitate to enter a Service Request if you feel the need. You start out conversing with the Tesla AI and eventually if necessary you transition to a real human to arrange the details of the actual service appointment if necessary. Describe whatever is happening in as great a detail as possible. You could even open a Service Request with your present battery health reading asking for a recommended next step.

I have a 2021 My Long Range that is at 82 percent with 43,340 miles to be exact which is about 280 miles at full charge.

It is a known fact that cold temperatures reduce the range of all EV's. Owners know this and adapt by plugging in every opportunity and knowing their actual expected range.

Oh, yeah you never know with a used car. But it's the same with gas cars, the engine could have been treated completely differently. With electric it's just easier to quantify.

How many miles?

Mine is similar....2019 m3 LR rwd with 40k gets 90% still. Parked outside in sw FL

The last time I ran the test, I had 103k miles and was at 83% battery health. 2021 MYLR AWD w/20” wheels.

The early M3s are increasingly being posted as being down 20% SoH. They dont seem to be as resilient as the MS design.

2023MYLR and I do not see the percentage in my tesla app.. where did you guys get this rating..

If yall have warranty use it!?

Range loss is completely irrelevant when it comes to battery replacement. It’s wholly an issue of percent of capacity. If you have extreme range loss, you should look at what’s draining your battery outside of driving

This looks pretty normal. Your are doing all the right things as well. Batteries loose health quickly in the beginning but then slow down. You will likely never see it go below 70% health.

I mean generally grippy tires or snow tires reduce range a lot. Bad rims. Lots of cabin heat on older cars with no heatpump matters a lot also when its cold. But generally on OEM tires and with the most efficient rims you should be pretty close to "original range" - "battery % loss" = "new estimated range" on the car's screen.

Yup CarMax is often "just an estimate" or based off someone's elses battery test. The Tesla test is official!

The number displayed will match the battery test expected result based off internal data estimates based off the car. Now running an actual battery test confirms it, and it will update the range calculation. On my car when I ran my battery test for the first time after a year and a half it did end up cutting my displayed miles down a little more from that point forward. The actual test revealed more degridation than the original estimate!

82% @60,400 miles. 23 M3P

Just a heads-up: the Tesla warranty is designed to catch outright battery failures, not normal degradation. I had mine replaced due to a fault and expected a new pack (or at least one near 100% health). Instead, Tesla installed a "certified" used battery that was already degraded to around 80%. Even though my original battery actually had better health numbers before it failed, they replaced it with what they deemed "equivalent" for the car's age and mileage. Don't expect a brand-new pack if you hit the 70% threshold; Tesla will likely only bring you up to a similar, used standard.
