 Ralph brings us another little quick tip that is great advice. He says, not sure if this comes under the barrier of not so cool stuff found, or if it's tips or tricks, I think it's the latter. He says, the problem to be solved in the last week or so, I've had trouble charging my iPhone XR. Yesterday, it would not take a charge, no matter the cable or the charger. A quick search revealed the most likely cause was lint in the lightning connector on the phone. And the suggested fix included using a toothpick to loosen out the lint and then and or using compressed air to blow the lint out. He says poking around in there with a toothpick seemed risky to me. So I proceeded to use the compressed air solution, which worked like a charm. Problem solved. Phone now charges as expected. Yeah, this is an age old problem, especially with lightning connectors because they're so thin. You definitely collect lint.
