Here is my update:
Over time, (after 1 month) my battery is a little bit better, like it can survive a day of light use, but some percentages drains without any reason.
Now Im more "worried" about the out of the box scratch on the back glass, the dust particle in the one mont old phone's camera, the poor fit quality of the camera button's frame, the earpiece’s deeply placed grill, that collect a LOT of dust.
Over all, im soooooo disappointed. Like, I spent 1350$ on that **** phone. Can’t i get quality??
Bdw, im from Hungary. This is not a country that like: “Oops, there is a random apple store.. Lucky mee!”
So I'm pretty helpless rn.
