iPhone X won't turn or charge

Put my iPhone X on charger last night . When i got up it is black screened and will not power on. I have tried the volume up down and then holding power on still nothing. iTunes won't even recognize it. I've tried different charging cables and blocks nothing will get it back on. I have no warranty so i would prefere to repare it by my own after i repared few iphones but i dont know what parts should i replace or what went wrong. Should i replace Charging port, batery or even a motherboard? Anny suggestions? Thanks for help.

edit: I even tried wireless charger but nothing so Iam unsure if replacing a charging port could help in this case or phone need to have some charge to receive power from wireless charger?

When troubleshooting charging issues, I would do the following (in order):

  1. Always try another Lightning cable and charger, preferably Apple original or MFi certified units.
  2. The Lightning cable 8-pin connector should be sitting flush with the housing and completely inserted. If it is not, there could be lint/dust/debris inside the port impeding a proper connection. You can clean it out with fine point toothpick or tweezers or a dental pick. Just be careful not to damage the pins inside the Lightning Port.
  3. Change the battery. The battery is the weakest link in the entire phone and certainly for charger related issues. It is also the easiest thing to replace. IF the phone boots, use a battery utility, such as coconutBattery (for Mac) or 3uTools (for Windows) to test the battery prior to removal. Anything less than 70% of design capacity will require replacement. If the phone doesn’t boot, measure the voltage directly at the battery with a multimeter. Anything more than 3.2V should allow the phone to boot.
  4. If the battery is in good condition, you can use a USB Ammeter to determine if the phone is really drawing current when it says it's charging. If it isn't drawing current, then I would change the Lightning/Charge Port.
  5. If a new battery and charge port still don't resolve the issue, then you either have faulty replacement parts (possible) or a logic board issue. There is an IC (commonly referred to as Tristar) responsible for communicating with the charging device and uncertified chargers can damage it. Unplug the battery and connect a known-good (preferably Apple original or MFi) charger to the phone. A properly working phone will show an Apple logo and boot loop. If the Tristar IC is bad then the phone will not do anything.

1. I tried different cables and chargers (all of them OG).

2. I checked the connector, there is no dust or grime and i also checked all the pins.

3. Ok, i will try measure voltage of the battery.

4. You don't get me. The phone doesn't turn the screen on even when its on a charger but i ordered the USB ammeter so I can measure if it drawing some current or not.

But shouldn't I get around lightning charging port by charging wirelessly? (When charging wirelessly doesn't work its mean the lightning connector is probably good and there is fault in the battery or motherboard?).

Thank you for useful thoughts.
