Mine looks just like yours! I got my '18 SV Leaf in June-15 and had 95.95. My 3mos adjustment happened 9/4-9/8 and lost 2.4!! I'm now at 93.06!
Here was my adjustment....
09/02/2019 95.5
09/03/2019 95.5
09/04/2019 95.28
09/05/2019 94.93
09/06/2019 94.15
09/07/2019 93.87
09/08/2019 93.09

09/09/2019 93.09
09/10/2019 93.09
09/11/2019 93.08
09/12/2019 93.08
09/13/2019 93.07
09/14/2019 93.07
09/15/2019 93.06
09/16/2019 93.06

Also like you, no matter what i do it still drops. But i do try keeping it around 40-70 SOC. I only have 3 QC and not by me.
I live in the midwest so its can get hot and humid but nothing compared to the southwest desert.

I was also playing around with cooling the battery somehow. I opened up the access cover on the back seat floor. I can feel the air when driving. When i put a bright light in the access hole and turn off all the lights in my garage and look under the car. I can see light coming out. You can see the airflow passages. But even if i try putting a fan in there or no matter what i do, i still loose about .01 a day or every other day no matter what. VERY DISAPPOINTING!!

What's your mileage though?

We are only around 1900 miles.
Almost looks like mileage doesnt matter.

Have any 40’s lost a bar yet.

Do the SOH changes seem to correspond to a loss in range of the same magnitude?

Maybe, but we haven't seen it documented yet. Cwerdna saw a Facebook post showing a 40kwh dash display with 3 bars gone, FWIW.

Maybe. I'm down close to 10% I'd guess, and my GOM shows 130 miles more often than 150 now. I don't take 150 mile drives.

Why is the FB report not "documentation" ?

My mileage is 2400. I don’t think mileage matters either.

Ok thanks. But our mileage is pretty close too. I'd be curious to see a 2018 with 20k miles.

Which one doesn't always go down?

With previous generation battery packs, the SOH will go up occasionally, like after a QC session. We do have one lonely instance of a 40kwh pack SOH going up - a little, once.
I have this picture in my head of some tech guy as Nissan sitting around laughing at us for watching leafspy every day.

But those battery health bars must be connected to something. When Nissan does a service, what exactly do they print out and give you?
I read here somewhere that someone had a five star battery rating. Is that all you get?
The free report should be named "owner evaluation of charging/driving habits" since that is all it gives you. There is a true test of the pack and its NOT FREE. Some reports I've its as low as $149 but since its shop time, prices will vary.

I don't really see the value of paying for the test unless you feel your range is not aligning with the number of capacity bars the car is displaying.

Probably because there is no evidence. I see a lot of claims on Facebook with no pix, no data of any kind. Just a statement...
