Charging MagSafe for iPhone, is the sticker harmful or not?

Question

iPhone

I got bored and stuck a sticker on MagSafe, I wanted to find out from those who fumble it contributes to more overheating or not, the case is made of aluminum if I'm not mistaken for more heat dissipation from this charge (probably) and because of the sticker whether it will heat up even more or not, it doesn’t feel clear, or should I stick it on my f*ck?

Answer 1

A regular sticker will not affect charging in any way, you can not use metallized stickers and other materials that are opaque to radio waves. Pay attention to the charging speed, if it has not noticeably decreased, then do not worry.
Heating of such a charge during operation is normal.
