Oh wow, TIL. Thank you for sharing that information and how you found it. Seeing how it will occasionally charge back up to 100% I may start using this feature as well.
The reason I had not yet was from seeing how other devices were affected in the past. Usually just a hard cutoff at 80% and never charged above that. Eventually even if you tried, for those devices the battery couldn’t charge to 100% again after a while. Having the iPhone occasionally charge to 100% should resolve that.

TL;DR - OP would like to have a tag system that can be applied to posts.
(E.g. “operating system, help, question, advice, etc, etc)
I do think a tagging system for posts can be helpful too OP
