If i charged battery to 100% every day, would it void the unlimited miles warranty?
Also what is the harm in using the mobile charger as a home charger daily?

Why do you think there is some harm in using the UMC as a home charger daily? That's how most owners charge their Model S. I leave it plugged in and have the cord hanging on a hook on the wall, and only take it with me if I'm going on a trip.Also what is the harm in using the mobile charger as a home charger daily?
The original post comes across as a new owner (or potential new owner) doing due diligence. I think that's the "why".Why do you think there is some harm in using the UMC as a home charger daily?

As for the question about home charging...
Some have noted that the 14-50 plug/receptacle wasn't designed with daily plug/un-plug in mind. (I don't know if that's true or not, but that's what was said IIRC.) Continuing that train of thought, some have argued that the wear and tear on the 14-50 plug and/or the adapter to the UMC might "not respond well" to daily use compared to a dedicated "daily plug" like the HPWC. I have no statistics or opinion on the subject; just sharing along data from previous threads on related topics.

Just to be clear, that's daily unplugging and plugging from the wall, not from the car. I use a wall bracket to hang the roach motel so there is minimal stress on the plug and only unplug the UMC from the wall for trips where I'll be needing it. Worst case is something like 20 cycles per year (not counting cycles at RV parks, etc.)
Nor do I. Only for trips, once or twice a month. The vast majority of owners would have no reason to put the UMC in the car every day. If there is wear from frequent plugging and unplugging, though, it would likely be in the receptacle not the plug, and they're cheap to replace.Good point. I don't unplug from the wall daily either. The Roadster and S85 14-50 plugs stay connected to the receptacle most of the time.
Charging to 100% every day won't void the warranty, but it will degrade the battery faster. Battery degradation from regular use isn't covered by the warranty.
Typically for day-to-day usage, keeping the battery charged above 10% and below 90% will give your battery the longest and best life, as it does not cause stress for the pack.
Most people charge between 50-90% of the battery and not more than that to prevent degradation of the battery...but I recall an extensive thread (Reducing range...not sure though) where most people discussed that 90% charging reduces battery degradation the most. Isn't this why Elon mentioned battery needs to be charged 90% all the time.
Correct me if I am wrong
Yes, thanks for the clarification. I should have said that more clearly. Thx.Just to be clear, that's daily unplugging and plugging from the wall, not from the car.

Worst case is something like 20 cycles per year (not counting cycles at RV parks, etc.)
However, if I find myself at a Supercharger near the end of a trip and don't need to charge to 100% since I'm not that far from home, will I be able to do like at home and program the system to stop taking a charge at 90% or will the Supercharger continue to charge until the battery is completely full?

The cathode in Li ion batteries forms defects (microcracks) due to stress caused by expansion and contraction relative to neighboring materials. It is simply bigger or smaller depending on whether it's charged or discharged. The more you discharge it, the more it changes size. And the more it changes size, the more microcracks it gets. These microscopic cracks lower the battery's capacity. That's one reason why smaller cycles, more often, contribute to longer battery life. That's why you should plug it in every night.
Heat aggravates the microcracking process, so keeping your battery cool contributes to longer battery life. And guess what? Your battery heats up more when used at a lower SOC because it requires more amps to keep your car going 65mph than it does at a higher SOC. That's why you should charge it every night.
Capacity fade also comes from the build-up of non-soluble deposits on the anode and cathode. This chemical process happens faster when the battery is warmer. It also happens faster when at a high SOC. But the process slows to a crawl when you drop the SOC to 80 or 90%, and slows only a tiny bit more at 50%. So if you are going to drive your car, keeping it charged in std mode has less impact on battery life (lower amps, less heat) than driving at a lower SOC. But if you're not going to drive your car for a few days, there are no amps or heat to worry about. That's when Tesla recommends putting it in storage mode, which keeps it at a lower SOC.
end of science lesson.
