Do any iPhones make the most of the upper present from a USB Battery Charging port?
Sure. I do know from my very own private expertise (utilizing a USB meter) that the iPhone 7 plus attracts as much as 2.1A at 5V. I by no means had the prospect to check it, however I do keep in mind the iPhone 6 would “complain” that it might cost slowly if I used a charger with lower than 1.5A capability.
Apple has an iPhone comparability device that may can help you acquire the Tech Specs for fashions from the iPhone SE (1st gen) to the newest mannequin. From what I can inform, all iPhones beginning with the iPhone 8 help quick charging which means it takes benefit of the upper present charges.
so I am unable to assume that it will use greater than that from a USB A socket
Your cellphone will solely draw what it’s able to drawing and the adapter is able to delivering. If solely 1A is accessible from the USB adapter that’s all of the cellphone will draw. Greater amp adapters may have the information pins shorted with the 200ohm resistor to “inform” the machine that larger wattage is accessible.
Newer USB-C chargers that conform to the PD spec (energy supply specification) will negotiate the cost price with the machine. They may require USB-C adapters of a minimum of 18W (18 / 5V = 3.6A)
