I agree that some of it is marketing, some of it is tech bloggers trying to get clicks, but some of it is also real science that does have an effect. You probably won’t notice when it goes into effect, just that battery technology will slowly get better. It doesn’t really matter how fast this can charge until it’s supported in the infrastructure (and most people will charge at home overnight anyway), so you’ll only hear that charging is slowly getting faster over time, not sudden leaps. It doesn’t mean it’s all smoke and mirrors though.
