In this video we are showing how to replace IPhone 6S Plus charging ic or N4500(U2 ic ).
This issue usually cause due to non genuine chargers and car chargers.The symptoms are fake charging ,all chargers doesn't support and phone discharge soon etc...
I have diagnosed this issue by the help of DC power supply , you can also use a charged battery to confirm the issue.If the phone turned on and doesn't respond to charge or fake charging then it indicates to charging ic or U4500(u2).I have used 380 degree centigrade heat with my setup, you can use as you are comfort with.
NOTE :- This work should be done by only professional technicians other wise you gonna brick your phone
