LG V40ThinQ (Unlocked)(S&D) (Open Box)

The phone came in a new brown cardboard box, with a generic charger and USB type C cable, the phone looked like new, with no scratches, no dents, no smells, dust, or any signs of wearing, not even fingerprints on it. The phone arrived at home around 4:30 PM, with 37% battery, tested the cameras, mic, speakers, and buttons, and proceeded to leave the phone on the table, at about 6 pm the phone was completely "dead", I thought it was kinda weird because an idle phone with that much battery even with apps running in the background usually lasts longer than 2 hours (the phone doesn't have any app installed). I didn't care too much about it and decided to plug it into the charger, the screen turned on, and displayed a message like "Phone will be fully charged in 3 hours 27 minutes" and left it charging. I came back about 4 or 5 hours later and to my surprise, the screen showed charging 0%, I decided to try with another charger and with another cable, and the result was the same, not charging at all, left the phone sitting there for about 2 more hours with a different charger and cable, but nothing changed, the screen was still showing "Charging 0%". Called a friend who works in a smartphone repair shop, and he told me the phone is not holding charge, so the battery is pretty much dead, and that the repair would cost around $ 120. (I was shaking my head in denial) Soooo apparently, this seller only cares about the aesthetic of the product but neglects its technical inspection. A product that looks like new is useless if it doesn't work. I'm leaving the country tomorrow, that was the main reason to buy this phone, sadly looks like I'm stuck with a fancy RENEWED paperweight. UPDATE: After further inspection, decided to use a wireless charger, and the Phone is charging and holding the charge well. In the end, it turned out to be a faulty charging port, and not a battery problem. (the Phone is still not charging via USB-C port)
