After iPhe 8 and X started up to 5 W for wireless charging, Apple pulled it up to 7.5 W immediately after iOS 11.2 was released. But today's new report insists that Apple can move towards 15 W by changing at least e wireless charging coil of 2018 iPhes.
Well! Screen cleaner
Currently, the main trade-off of using wireless charging the iPhe 8 or X is speed. There is no doubt a useful element for not having to use the Lightning cable, but sometimes it may outweigh the ability to quickly juice up.
It should be noted that Samsung supports 15 W high speed wireless charging with a new smartphe, China time Today 's Apple says it will introduce a new wireless charging coil to the line – up in 2018 and will move beyd the current 7.5 W limit.
The iPhe 8/8 Plus and X use a flexible printed circuit (FPC) for the wireless charger coil. e of the main advantages is that the FPC coils are thin and light, but the drawback is lower than the ideal efficiency and susceptible to overheating. According to this report, due to FPC inefficiency, iPhe 's 7.5 W wireless charging is often slower than 5 W wire charging.
To provide faster 10 W or 15 W wireless charging, Apple is said to be using copper wire coils for at least e of the new iPhes. Compared to FPC, copper coils offer both higher efficiency and power capability. However, the workaround for the copper coil is to be thicker than the flexible printed circuit.
What about you, are you looking forward to a faster wireless charging speed? If it can not be used in the entire line-up of 2018, will it be a factor to select iPhe? Please share your thoughts with the comments below!
