Hello, I got my iPhone Xs Max last week and the wireless charging seems quite slow on my unit. It's like it's charging at 5W speed instead of 7.5W speed like on the iPhone X I had before. I use a mophie wireless charging base. The charging speed is roughly the same as the wired 5W charger : 5% every 10 minutes In 30 minutes charging, I only get 15% battery, whereas it was closer to 20% on my iPhone X (as far as I can remember). I still get 50% in 30 minutes when I use a USB-C 29W charger. Also my unit gets very warm when charging wirelessly. Is this normal or should I be concerned ?
