Apple's 2019 iPhones are still far from launch, but a new investor note from TFI Securities research analyst Ming-Chi Kuo suggests that the phones will be equipped with reverse wireless charging. For those unaware, reverse wireless charging or bilateral charging is a feature that allows for phones to act as wireless charging pads, enabling them to two-way charge any Qi-based device. This two-way charging has become a trend of sorts in this year's flagship phones, starting with the Samsung Galaxy S10 series, the Huawei P30 series, and is now rumoured on the Apple 2019 iPhones.
Kuo's note was obtained by MacRumors, and it reiterates that this year's iPhone models will come with reverse wireless charging. He corroborates an earlier report by Macotakara. This means that you will be able to charge AirPods and the Apple Watch by just placing them on the back of the new iPhones. This comes just after Apple announced that the AirPower charging mat has been cancelled, claiming that it didn't manage to "achieve our high standards."
In the latest investor note, Kuo claims, “We expect the new 2H19 iPhone models will support two-way wireless charging. Though the iPhone is not the first high-end smartphone to be equipped with two-way wireless charging, this new function could make it more convenient for users to charge the new AirPods and create a better integrated user experience of the iPhone and AirPods.”
Kuo says that Apple will supply battery boards from Compeq and the two-way wireless charging controller from STMicro. He also says that the new iPhones will come with larger battery boards and battery pack capacity. The iPhone XS Max successor's battery capacity could increase by 10 to 15 percent, and the iPhone XS successor's battery capacity could increase by 20 to 25 percent. The iPhone XR battery capacity to increase only by 0 to 5 percent, Kuo says.
