Range Loss Over Time, What Can Be Expected, Efficiency, How to Maintain Battery Health

Oh man - there is a TON on here about that. Search the forums and be prepared. The simplest answer is to do what Tesla says - only charge to 90% unless you are planning a trip. And plug in every night. Use Superchargers when you have to but not all the time. But - you can find one million other opinions on here and elsewhere on the internet. At some point you have to figure out how much (potential) incremental improvements are worth to you.
Avoid extremes as much as possible. That means avoid high and low SOC, though low SOC may be better than high SOC. Avoid fast DC charging as much as possible, and avoid fast discharging as much as possible. Discharging means flooring it. Since it's impossible to avoid these extremes, just avoiding them as much as possible is the best you can do to maintain battery life. Even so, expect some deg just from time passing, but you may be able to delay it for a while.
Hey fellow Tesla Drivers. I wanted to get your insight in charging habits. I been doing some research and there are a lot of different opinions when it comes to charging. So I get free charging at work with a Tesla plug, I work 5 or 6 days a week. I'm trying to figure it out if I should charge everyday to 80% (My daily commute is about 20%, so it would be 60%-80% daily)? or should I skip charging until the battery hits 20% and do a full cycle up to 80%?
In the manual says that "The most important way to preserve the Battery is to LEAVE YOUR VEHICLE PLUGGED IN", I'm trying to prolong the battery longevity as much as I can and comparing different opinions in the subject...
I appreciate in advance your help in this topic

Shallow charging is preferred to deep discharges for longevity. 80/60 is fine.Hey fellow Tesla Drivers. I wanted to get your insight in charging habits.

yes, sentry uses 300w, passive venting another 200-600w. 1% for a new long range is 700wh and for a nw SR like 500wh.

if you live somewhere warm charge to 80%-85% everytime you get home (texas, australia, Spanish summer etc). If you live somewhere cold (i.e. germany, uk, france etc) just charge to 90% every day. Tbh the evidence that letting it sit at 90% in hot climate is actually quite poor anyway. Dont deep cycle if you can avoid it.

Ever since I've purchased my 2019 LR AWD, I've charged it using the Tesla Wall Connector in my garage.
When charging, it says it's doing so at 48 amps. I'm never in a rush to charge. Should I set the charger to something lower than 48 amps? Would this help with battery longevity?
For reference, I keep the battery between 30% - 80%, maybe charged it to 100% three times before a long trip, and supercharged it no more than five times. My 100% range has already gone down to 290-ish miles with under 15k on the odometer.

There is virtually nothing you can do charging-wise besides taking the car to 0% and leaving it there for weeks that will have any noticeable impact on battery life.

not necessary. even 48A is already a pretty low charging rate.

There is no statistical evidence that stopping at 80% will have any positive effect on battery degradation. This is a relic of the very first Nissan Leaf models that had an 80% charging point for daily driving. Every Tesla vehicle has their daily driving charging point set to 90% by default.
But why does it matter? If you drive a 176 mile leg, a normal person would stop for a bathroom break, and coffee, anyway. ABRP isn't optimizing for longest legs between charges, but for fastest trip times. We know that fastest trips times happen when you drive fast, and charge at low SOCs.
