"Health" / readiness of battery after charging or not

Bear with me, as I know there could be many factors and variables, including just flat out placebo effect. However, I very much noticed a difference in launching and performance last night and this morning.

Yesterday, I took my car back to the body shop to fix the alignment of my grilles and headlights. As a courtesy, they always charge it up for me. When I got it, I noticed it had a whopping 18 mi electric range (I never see more than 14-16).

Immediately upon taking it to the street, I noticed that launching felt very good...eBoost seemed to come on without any lag and made for a very fun driving experience.

I parked it over night without charging, and when I took it out this morning...it behaved how I feel like it normally does. It felt laggy on launch, eBoost didn't always kick in right away, and when it did it came like a surge.

I currently have it on a ChargePoint charger now (same as what's in my garage), so I'm interested in seeing how it will perform with a full charge, but I was curious if anyone else has seen this or if there is an official best practice here. That is...do we need to charge it to 100% for optimal experience? Even if leave it overnight with the standard 75-80% you typically have with Sport Mode? Or could it be the charger itself? I wouldn't think the one at the body shop is any different...and 100% is 100% right?

Just drives me nuts sometimes (no pun intended). I love this car, but sometimes I feel like it's woefully inconsistent.

Electrons are electrons. Once the battery is warm it makes no difference if it's 90% full or 40% full (until it runs out). And we've discussed the estimated mileage many times. It's derived from an algorithm of prior use and eventually settles into something close to 15-17 miles for real world use.

Yea, the range wasn't necessarily the highlight here. Just pointing out all the details.

Was the car preconditioned when you picked it up compared to not being preconditioned the following morning? Temperature difference?

If the batteries are not at optimum temperature then electrical energy will be used to cool/heat them and I would also expect the available electrical power would be reduced until that optimum temperature is achieved.

I have noticed variations in the level of eboost in different conditions but have never had time to carry out a detailed test of what happens in different conditions etc.

There are a lot of factors that go into the 'power delivery algorithm'. The drivetrain is 'protected' during warm-up and other situations.
