iOS 11.2 to unleash ‘fast’ wireless charging for the iPhone 8, iPhone X - Computerworld
Apple is preparing to release iOS 11.2, an update that will enable 7.5W "fast charging" for the new iPhone 8, iPhone 8 Plus and iPhone X.
Currently, iOS v11.1.1 supports only 5W wireless charging;
Here's a list of Computerworld's top 10 wireless chargers, most of which support the "fast charging" capability.
Why Apple chose a slower version of wireless charging than the latest Android smartphones, which offer 10W of charging power, is unclear.
Those costs rise in tandem with the power level, according to Menno Treffers, chairman of the Wireless Power Consortium, which oversees the Qi wireless charging standard.
