Why aren't all USB connectors like this?

Phone charging...  once a day.  365 times a year.   The 1500 cycle life of a USB connector would be used up in 4 years!
glarsson:
That's why our phones don't have USB for charging. :-)

I had a USB 2 extension cable fail through loss of contact pressure after leaving it plugged for a couple years. It was a cheap cable, however, and could very well have used deficient spring metal.

Wouldn't help. Too many people ignored the specifications and skipped certification. They misused the USB logo or just omitted it entirely.

A very good point.

I think I've charged my phone from a computer 2 or 3 times in a pinch, but the rest of the time I've used the wall plug charger that comes with it.
