Fix iPhone 7 Dead/ Not Charging – Charging IC/ Tristar Repair

Today we’ve received a dead iPhone 7 and it wasn’t charging or even turn on by the power supply. by the power supply, it was pulling 0.24A and it was stuck on it. How to fix iPhone 7 CHARGING IC?

first of all, we’ve put it under the thermal camera to find out which part is faulty and when pressed the power button we could see properly on camera which part caused the issue.

As You can see in the picture there is the red bright spot on the thermal camera and shows that 34c and that part is famous charging IC or technically we call it Tristar.

So we have replaced the Charging IC/Tristar with the brand new Tristar IC and phone starts working again like that issue never happened before.
