Changing the charging cables for a billion phones to reduce E-waste would be an effective way to turns billions of perfectly good cables into E-waste. Do you feel it would break-even within ten years?

I don't think you're factoring in that many of those cables would need replacements during the lifetime of the device they're used with.

So yes, I think that it would "break-even" quite fast.
