Out of curiosity, what percentage battery life does it say your iPhone X has now? Also, have you wirelessly charged your X frequently?
As for "unethical", I can't completely agree and I'm no fanboi. Apple was wrong in the way they did it; they should have been upfront with what was going on instead of hiding it. But they were trying to fix a valid issue -- the fact that those phones would unexpectedly shutdown if they needed more power than the battery could provide. I do believe they've done the right thing now, though, by showing the max battery charge (compared to a new battery) and warning you -- and giving you the choice, between throttling or risk of shutdown -- if your battery is under the threshold. I personally view it more as the Apple "Knows Best" attitude, where they choose what they think the right answer is rather than giving users a choice.
