Context: My understanding is that there are many power outputs for usb chargers, many of which will charge the 14 Pro Max. For example, 5v 1A (old triangular apple charger), 5v 2A, 5v 2.4A (bulky wall plug for older iPads), 9v 2.2A (apple 20w usb-c wall plug). The list goes on. I also know that plugs with higher outputs such as the 30w have variable outputs to suit what the device will draw.

I have been using my old triangular plug to charge my iPhone 14 Pro Max. I wake up some mornings and it is only on 95-98%. Whilst this could be attributed to a poor sleep routine since getting the phone which is affecting the optimised charging, I’d like to use a higher powered charger to hopefully resolve this.

I have also read that fast charging (let’s assume fastest possible charging) can heat the battery up, and charging warmer batteries is slightly less healthy than ambient temperatures.

My question therefore is this: what would be an optimum charger power rating that will sufficiently charge the phone in reasonable time, but not be constantly fast charging the battery? Is there a good middle ground? Help appreciated!

Hey everyone, I recently purchased a refurbished iPhone 14 after years and years of owning an iPhone 6 (don’t ask). Battery health is 97%. I really need help figuring out with charger I should buy, like which wattage, which wire, usb-A or C etc. I really have no understanding of Watts and all that stuff so would appreciate if anyone can give me a run down. I was given a USB-A wire with a made for iPhone stamp on it with the phone. I’ve seen some Reddit posts that say using a 5W wall charger would be good for long term battery health and that even though usb-C is faster, long term battery health wise usb-A would be better??

Would really appreciate any help. As you can tell I’ll probably be using this phone for the next decade so need it to last.

Some people are suggestion that 3 pin 20W charger
