Apple has integrated its first wireless charging smartphones in its 2017 and decided not to roll forward without technology being tested. So, at launch, the wireless charge was relatively slow, similar to standard plug-in, but with iOS 11.2, it will get support for stronger chargers where needed. This move is not at all surprising, as company representatives have announced this since the iPhone 8 was released.
Those who have the ability to test iOS 11.2 have already confirmed that the iPhone 8 devices now have wireless charge support at 7.5W, a 50% increase in power compared to the 5W that could initially be used. Thus, using compatible wireless chargers, iPhone 8, 8 Plus and iPhone X will charge about 45% faster than before, even faster than the cable and charger included in the package.
Apple has already sold two models of wireless chargers from partners in its stores, both Belkin and Mophie offering 7.5W load capacity. Of course, there are more powerful chargers on the market, but they cannot be used to the maximum capacity if Apple does not unlock this capability through its software. Wireless charging can cause the device to overheat, and Apple is likely to test the increase in charging power in the future if it does not damage the phone.
Since the wireless wired charging on the iPhone 8 and iPhone X is made using a more powerful laptop adapter, it is very likely that in the future we will see a new increase in charging speed over the 7,5 W possible in this moment. Most likely, the next “upgrade” will come alongside Apple’s proprietary Apple AirPower, which will be launched sometime in 2018.
