| 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! |

That's why our phones don't have USB for charging. :-) |

It was a cheap cable, however, and could very well have used deficient spring metal. --- Quote from: tsman on January 20, 2019, 11:04:45 pm --- --- Quote from: jfiresto on January 20, 2019, 08:04:48 pm ---The standard could have fixed that by using "shall" rather than "should".... --- End quote --- Wouldn't help. Too many people ignored the specifications and skipped certification. They misused the USB logo or just omitted it entirely. --- End quote --- 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. |
