Last year Apple finally introduced wireless induction charging on both iPhone X and iPhone 8 and 8 Plus, a charging method that some users are not convinced by because of how inefficient it can be. This problem would be solved later this year according to a report by China Times , as a new copper coil would be incorporated into the new iPhone 2018 that would offer a much more efficient charge.
According to this report Apple would opt for coils with thicker copper wire with lower resistance as opposed to what we see in the iPhone currently incorporating an FPC coil. This will also help reduce the heat generated during charging, which can be quite annoying when using it after recharging.
Reducing the coil resistance will allow Apple to increase the power threshold of the iPhone to be able to recharge without any overheating, so it will be possible to have a much faster and more efficient charge through the Qi certified chargers.
This charging model will only be available on one of the three iPhone models to be presented this year. The rest will continue with an FPC coil which is a mixture of iron, other metal and plastic. Obviously a copper coil will be much more efficient than an FPC.
The one responsible for having only one 7.5W load power in a wireless way is the responsibility of this FPC coil, so soon we will see devices with a more efficient load something we would appreciate.
Without a doubt, today the low efficiency of wireless induction charging, coupled with the heating that some iPhones suffer, means that many users choose to recharge their device in the traditional way and not using a charging cradle.
