Wireless Charging Is a Disaster Waiting to Happen

I have a standing desk that came with a built in wireless charging spot. It&#x27;s slightly raised above the surrounding glass, so my laptop doesn&#x27;t sit evenly on that end of the desk. If I want to charge my phone, I have to push my laptop partly off the edge to make room. It doesn&#x27;t charge as fast as my cable. It makes my phone heat up.<p>I still think wireless charging is a gimmick. I&#x27;d rather have a cable and a port that&#x27;s easier to put in and more resistant to wear&#x2F;breakage&#x2F;clogging. Or a desk with a little stand that I can just drop my phone into and it&#x27;ll make a physical connection and charge more efficiently.<p>A final advantage to cables: if you want to charge wirelessly, you have to put your phone down! With a nice long cable by your bed, you can lay there and use your phone as long as you want.

Choice quote:<p>&gt; In my tests, I found that wireless charging used, on average, around 47% more power than a cable.

One flaw I note in the article, which is supposed to be all about charging efficiency:<p>Not once does the article cite a single figure on the actual charging efficiency achieved in any of its tests.<p>Yes, it does say that &quot;47% more power&quot; was used, but this is of course not the efficiency. It allows you to calculate the efficiency, which most people would screw up.<p>Not great.
