Apple’s next iPhone models to be released in 2019 are thought to pick up a feature akin to Samsung’s PowerShare found on the latest Galaxy S10 phones.

Reliable Japanese blog Mac Otakara reported this past Friday, based on information received from unspecified Chinese supplier sources, that Apple’s next iPhone update might very well include a new bilateral wireless charging feature. It would let the phone wirelessly charge Qi-compliant devices such as an Apple Watch or the new wireless charging case for AirPods.

Ahead of Samsung’s February 20 Galaxy S10 press event, realiable Apple analyst Ming-Chi Kuo of TF International Securities predicted that 2019’s iPhones would support bidirectional wireless charging (along with larger batteries and other upgrades).

Here’s a look at the PowerShare feature on Samsung’s S10.

Mac Otakara corroborates that information, adding that Apple might finally swap the slow-charging 5W USB power adapter with the 18-watt adapter for the 2019 iPhone models.

The power brick will be compatible with the USB Power Delivery protocol to support fast-charging and provide overcharge protections and more. This means that people who buy a brand new iPhone model this fall will be able to go from dead to fifty percent charge in about 30 minutes, by using just the included charger and the Lightning to USB-C cable.

Apple’s 18-watt USB-C Power Delivery charger currently ships with the new iPad Pro models introduced in 2018 (the company is offering the charger standalone in exchange for $29).

Today, using the fast-charge feature on an iPhone 8 and later or an iPad Pro means buying a Lightning to USB-C cable from Apple or a third-party along with a USB-C charger.

Now, bidirectional Qi charging would be really cool.

I never though I needed wireless charging until it arrived in my iPhone. I’m smarter now—I can think of a bunch of situations when being able to quickly top up a low-powered device like my watch or AirPod would be very convenient.

On the other hand, even though iPhones have pretty decent battery life, topping up another device’s battery wirelessly may put an unnecessary strain on your iPhone’s battery. In other words, using such a feature would deplete the battery faster, requiring more recharges and shortening its lifespan.

2019 models will include the same screen sizes as in 2o19: 5.8, 6.1 and 6.5 inches. This probably indicates successors to the current iPhone XS, iPhone XS Max and iPhone XR models. Kuo told clients that all three new iPhones will retain the Lightning port instead of USB-C.
