To make matters worse, the article then exaggerates the problem while attempting to contextualize it: "“We worked out that at 100% efficiency from wall socket to battery, it would take about 73 coal power plants running for a day to charge the 3.5 billion smartphone batteries once fully,” iFixit technical writer Arthur Shi told OneZero. But if people place their phones wrong and reduce the efficiency of their charging, the number grows: “If the wireless charging efficiency was only 50%, you would need to double the [73] power plants in order to charge all the batteries.”" See the problem? Not a single one of their tests with a phone lined up properly on the coils had efficiency this poor. Neither was the average efficiency in their tests ever this poor. MagSafe has already fixed the alignment issue and one can certainly assume the entire Android world will have followed suit before too long.
