Reverse wireless charging has been adopted by multiple Apple competitors for years, which is a typical practice since the technology giant habitually adopts these standards much later. Even though a multitude of iPhones has supported Qi wireless charging, it will be the first time that reverse wireless charging makes an entry to the iPhone 17 Pro and iPhone 17 Pro Max, assuming the latest rumor ends up being true.
The new reverse wireless charging feature on the iPhone 17 Pro and iPhone 17 Pro Max could reach 7.5W, but it can only be viable if these models ship with larger batteries
On Weibo, a user with the handle Setsuna Digital mentions that Apple has been testing reverse wireless charging technology on the iPhone 17 Pro and iPhone 17 Pro Max, with a maximum wattage support of 7.5W. Even though the Cupertino giant was taking its sweet time to adopt this form of induction, the aforementioned wattage will be higher than what Samsung’s current-generation flagship, the Galaxy S25 Ultra, and last year’s model, the Galaxy S24 Ultra support, which is 4.5W.
The technology will be handy when topping up other devices that are low on juice or perhaps giving the AirPods case a much-needed charge so they can last for just a little longer. While it can be convenient on a certain number of occasions, there is one obstacle that Apple has yet to scale that would make reverse wireless charging on the iPhone 17 Pro and iPhone 17 Pro Max truly viable; increasing the battery’s size. As of right now, the biggest cell the company has ever added to its iPhones is 4,685mAh and is currently found in the iPhone 16 Pro Max.
Samsung’s Galaxy S25 Ultra packs in a much bigger battery, and that too can deplete rapidly when reverse wireless charging is enabled. Fortunately, both Apple and Samsung have been rumored to be working on silicon-carbon technology that would allow the batteries to not just increase in capacity but also not compromise on the thickness either. An iPhone with a 5,500mAh battery that also supports reverse wireless charging would be an ideal combination, but there is no telling if Apple will ever implement it, so treat this rumor with a pinch of salt, and we will be back with more updates.
