A 100% or Range Charge has a few issues.
At the extremes of charge there is deposition on the electrodes and chemical chages which reduces the batteries effectiveness. Watch
"Why do Li-ion Batteries die ?..."
A good charge controller can minimize this problem by monitoring individual cells and not overcharging some while still charging others. This is why you can charge 80% of the battery in 40 minutes but need 35 more minutes to get to 100%

The worry is that using 100% charge all the time will reduce the range available from the battery faster than not. The degredation is going to happen anyway. When batteries are reported as have N cycles those are full charge/discharge cycles; avoiding those extremes can allow a good battery last a very long time.
An iphone does not let you actually charge to 100%, it leaves a buffer at the top; a dumb but effective charge controller. There is rumor that a software limited Tesla 60kWh battery is similarly limited at the top of the capacity so 100% is not really 100%. So while the interface would look the same the risk of 100% would not be an issue.
Reports here suggest batteries lose a bit of range early and then very slowly lose more range over time regardless of the max charge setting. There are threads here about using a near-zero drain followed by a charge will 100% to recalibrate the rated miles calculator but that is not doing anything to “fix” the battery degredation.
Tesla recommends daily charging in the 50%-90% range and charging only to 100% if you really need the range before your next charging opportunity. 95% is probably ok, too. They also recommend only charging as much as you need to before your next Supercharge if you are on a trip so most recharging happens in the low-charge/fast-recharge zone. Spending time charging that last few percent overnight in your garage may not be burdensom but waiting at a supercharger to find a home for those last few electrons is often a big waste of time.
Another way to ask the question is Why not charge to 90%? Only good reason is that you really need that last bit of range for your next leg.
BTW did you use a discount code for your recent order? It’s not too late ;-)
