The firmware 4.5 release notes where just leaked on this forum. What struck me was that they removed the "standard" and "range" mode, and just replaced it with a "% charge" slider. It is seems reasonable to assume that this will lead to much more charging to 100%, since there is no longer a sub-100% default. The intention behind standard/range was to limit the frequency of owners charging to 100%. I have several times heard Elon Musk urge people to charge to 100% as often as they feel they need it, and not worry about the battery. The question of battery degradation has been one of the main concerns regarding the long-term viability of the car. The change Tesla have made in 4.5 indicates that they view "battery anxiety" as a bigger issue than the potential degradation of the battery by people charging to 100% all the time. Is not this a very strong indication that they are not very worried about battery degradation at all?
