Now I have higher-end phone (AQUOS zero2) but it doesn't feature Qi to make it lighter, and I love the decision. Previously I had Galaxy S8 that features Qi but I don't use it much because it gets hotter while charging so not seems good for battery health.

Adopting Qi has another side effect: it prevents using metal to back surface, so most high-end phones choose to use glass rather than resin so phones are much getting heavier.
