"Given its strength, titanium is remarkably light. When compared to steel in a strength-to-weight ratio, titanium is far superior. The metal is as strong as steel but remains 45% lighter. In fact, titanium has the highest strength-to-weight ratio of all known metals".
And if you see the test, the titanium skeleton doesn't break at all on the bending test, it's the glass part that breaks only.

The content you quoted:
> “The metal [Titanium] is as strong as steel but remains 45% lighter.”
So, if the steel frame wasn't a problem stength wise, the titanium should be one either is my point.
Because I felt like the parent's comment "The previous iPhone used a steel frame. The titanium makes it lighter, not stronger" was about how titanium is at fault here (implied: weaker, not just "not stronger").
