With less than 24 hours waiting for Apple to unveil the iPhone 11 – or whatever they are called – the most trusted source of Apple rumors is back from its prediction that they contain inversely wireless charging that you would use your telephone to charge your wirelessly rechargeable AirPods case.
Apple analyst Ming-Chi Kuo does not fully say that the feature has been permanently canceled, but that it may have been thrown away because "charging efficiency may not meet Apple's requirements," according to 9to5Mac.
If so, it would not be the first time in recent memory that Apple was struggling to bring wireless charging to its standards; Apple got a rare black eye this spring when it abruptly canceled its publicly announced AirPower charging pad after several delays. And the biggest competitors of Apple, Samsung and Huawei, both have the function in flagship telephones.
Charging efficiency is important however; if users expect to be able to tap two Apple devices together and allow each other to charge each other in a meaningful period with a meaningful amount, that efficiency must be high – and that is not always a given when we talk about beaming current through the air with the help of inductive coils.
In general, wireless charging is quite far behind when it comes to cabled charging in speed, that's why the different what Kuo predicts now makes perfect sense: the two high-end iPhones are reportedly now supplied with an 18W USB-C fast charger (and presumably a USB-C to Lightning cable) in the box, instead of the slow 5W charger where Apple has previously been ridiculed for. He says the cheap successor to the iPhone XR will still contain that slow charger.
It is worth noting that Kuo is not the only one predicting that the new iPhones would come up with reverse charging, so he is not the only one who may go wrong: as we wrote earlier, both Bloomberg and Japanese blog Macotakara predicted the same. Apple may be a powerful company, but it cannot necessarily remove a hardware-dependent function from a phone the day before it is announced; that decision was probably made months ago and it can show how long it takes for these rumors to find their way to us.
