Unfortunately, for all its innovation, the phone didn’t catch up. In fact, manufacturers would ignore wireless charging up until 2013 when they started pushing it more actively.[br][br]“Fast” wired charging was born relatively late in the game – 2014. There’s no firm definition of the term, so we’re counting phones that can go above the 10W provided by plain USB.[br][br]Qualcomm introduced Quick Charge 2.0 with its Snapdragon 800 chipset (and other chips from the family). It supported up to 18W, though 15W was by far the more popular option (still is today).[br][br]In the other corner was the VOOC charge, which ran at 20W. Quite impressive for early 2014, when you consider that some of the priciest flagships today only go up to 15W. [br][br]Despite an early start, wireless charging was slow to gain popularity. As you can see from the chart below, fast wired charging quickly overtook it and is featured on the most popular phones today.[br][br][img src="/storage/emulated/0/Download/gsmarena_001.png"][br][br]Of course, the flagships of today often offer both wireless and fast wired charging, but that’s a relatively new development that started last year. [br][br]Fast wireless charging has also started gaining traction. We didn’t put it on the chart as there’s really only one relevant data point, but as of this year, the most popular phones with wireless charging can go above 10W.[br][br]In fact, while some brands share technologies, the fast wired charging standards are quite fractured. The USB-IF is trying to bring everyone under the USB Power Delivery banner, but its only notable success so far is the compatible Quick Charge 4.0+.[br][br]Source: https://m.gsmarena.com/counterclockwise_wireless_charging_came_first_but_fast_wired_charging_is_more_popular-amp-36760.php[br]
