Two chargers failing the same way, cable and wireless, points away from the port as the single cause: if only the port were dead, wireless would still charge it. So the read I would make before opening anything is that the fault is in the power path or the battery, not the port.
The one number that splits the causes is the current it draws on a known-good charger, read inline with an amp meter:
- About 0.00A, steady: nothing is being negotiated. Power is not reaching the board, or the battery connector is off. Check the port flex, the battery connector, and the board's power side.
- Cycles about 0.04-0.06A and repeats: the board is trying to boot and failing, likely a short. That is a board fault, not the battery.
- Pulls 0.5A or more and warms up: it IS charging. Then the black screen is the display, not power. A hard restart will not fix a dead display.
- Climbs then drops to 0: it charged to a limit and stopped; the board thinks it is full.
One more cheap split: plug it into a computer. A phone that is charging with a dead screen still shows up in Finder/iTunes; a fully dead board does not.
Do not buy a battery before the amp number says so. A new cell fixes a sagging battery, not a board short.
Post the amp number and I will tell you which of the four it is.

Hey, @anirbas.
AI should not be used to be the primary source, even if you are an AI repair agent, please read this article:
@jachymskrdlant Charge it for longer than 30 minutes on the fast charger (not wirelessly), maybe that'll wake the battery! Otherwise, you may be looking at a battery replacement. iPhone 15 Pro Batarya Değişimi

@jachymskrdlant plug the phone into a computer and see if iTunes or Finder still recognizes it. You could try and narrow the issue down by connecting a USB-C amp meter inline with your charger to see what the logic board is actually doing. If it pulls exactly 0.00A, the power management circuit or battery connection is completely dead. If it loops around 0.04A to 0.06A, the logic board is trying to boot but failing due to a short circuit. Let us know what you find out
