Charging Your New iPhone With The Wrong Cable Might Slow Down Your WiFi: Here’s Why
There are a lot of factors that can affect the way an iPhone (or any smartphone, really) performs in various aspects, and theiPhone 15is no exception. It’s not because of bugs or glitches, or the result of a hardware failure, but due to certain connected accessories.
In fact,Apple itself has statedthat users may begin to notice reduced wireless speeds — over Wi-Fi, cellular data, or both — because of a non-compliant USB-C connection. Meaning if you physically plug your iPhone 15 into aUSB-Cconnected accessory or a USB-C cable that doesn’t follow industry standards, you could run into problems.
It may seem illogical since USB-C cables are used to directly transfer data between devices while wireless connections are a different form of data transference entirely, but the reason for this issue is simple: Interference. More obvious obstructions like physical barriers or a bogged-down network can certainly do their part to slow down your wireless connections, buteven electrical interferencehas been known to have a similar effect.
Dealing with (or avoiding) USB-C signal interference
If you suspect or expect a dodgy USB-C cable is slowing down your iPhone 15’s wireless speeds, there are a few simple steps you’re able to take:
But if all else fails, sticking with official Apple accessories and cables should result in the least amount of friction. Apple recommends using aThunderbolt 4 (USB-C) Pro cablefor both high transfer speeds and minimal interference.
