I have a OnePlus phone and I know that to fast charge it I need to use a special USB cable.
But Samsung phones, for example, also have their own fast charging cables.
So why can’t those phones fast charge with the other manufacturer’s cables if the cable is able to transfer enough power anyway?
At the end of the day the cables are simply transferring electricity, and the more watts the faster it should charge, no? At least that’s the way I see it
In: Technology
there is actually more to the cable that just wires. many have small IC on the connector that interacts with the charging circuitry on the device. Why/how they don’t work across manufacturer is beyond me. might be intentionally proprietary so you only use a cable that will not damage, or so that you have to buy/use their cable. I think the QuickCharge standard that Qualcomm developed was an attempt at a standard across devices, but it would require the use of a Qualcomm chip or at least the licensing of the technology, so that will only go so far.
