According to the Apple iPhone's supply chain, Apple may switch to a copper Qi coil in the 2018 new iPhone's heat sink. This change will improve the charging efficiency of the new iPhone.
As a new trend in wireless charging, various mobile phone manufacturers are moving toward high-power and high-efficiency. However, it is still difficult to achieve this goal with regard to Apple's existing ferrite polymer composite (FPC) coils. Therefore, in the 2018 Apple iPhone series, the traditional heat sink material will be replaced, at least one iPhone model will be replaced with a thicker copper coil to offset the thermal impact of the increased wattage.
After reducing the resistance, Apple can increase the safe charging power threshold for wireless charging of the iPhone without overheating, which can improve the wireless charging speed of the iPhone, but it still depends on the output power of the battery pad. In the case of increased, a thicker, more uniform copper charging coil would be a better cooling solution. However, Apple may not want to thicken the iPhone to accommodate copper coils, so the accuracy of this report is not certain.
It is widely expected that three new iPhones will be launched this fall, including 5.8-inch and 6.5-inch OLED models, and a 6.1-inch LCD iPhone. Most sources said that all three models will use Face ID. However, the price of the LCD model is lower. As for the LCD version of the iPhone will not enjoy this new cooling technology, we still do not know.
