Video here https://youtu.be/RJ3zIH5dF2M I have ran into this problem a couple times before where an Iphone 6 will only read some chargers. There don’t seem to be any correlation between when it will charge are not. I’m using ONLY apple parts and on the last test is when I plug it into a computer. I have switch around the cables between the computer and adapters and the result was constant with 12 or more cables cables. I’ve replaced the charging port and the issue continues the same chargers work or don’t work as the first test with the OEM port. The chargers have been used to charge 25+ devices so its not just the one testing devices working with all chargers. No water damage. Is any one else having this issue?
Is it just that phone or have you had this issue with other phones as well? You could try transplanting the charge port from the device you know it works on to the device it is not working on. If that doesn’t work, check the connector for the charge port to the logic board for damaged/missing pins. If there isn’t any damage and the transplant doesn’t work it is most likely IC chip is damaged and would need to be replaced.
The reason for this problem is theres to many fake usb cables to charge the iphone but all its doing is ruining your phone as it should only be charged with the proper apple charger and you can google it and youtube to see the difference and after a while of using these fake leads is it will pop up on your iphone saying that it isnt a reckonised the power lead and if thats the case dont keep using it go out and buy a proper apple usb charging lead and it is afew pounds more but its worth it in the end.? Good luck
