I just today got a USB C to Lightning cable and am experiencing the wonders of fast charging. I am convinced I can't go back to normal/slow charging anymore. My only concern is, are there issues with fast charge shortening battery life compared to normal/slow charging?
I was just talking to an Apple employee and asking about fast charging. She said she uses the fast charger with the USB-c cable and her husband sticks to the slower brick that comes with the phone. After using them for awhile, her battery health was down to 92% while her husbands was 99%. So the question is, does fast charging degrade your battery overall health over time? Or should you just stick to using what came with the phone and charge over night?
