iPhone 6 Won't Boot or Charge: Troubleshooting Dead iPhone, Replaced Battery & Input Tried

Hello ,

I have an iPhone 6, unfortunately, one time it discharged and it would not start anymore, with one exception.
I will add that the charger is certainly functional - I checked another model.
Phone for about 2 weeks, does not respond to the charger and the power button, while charging, the charger is cold.
A week ago I connected to charging and, surprisingly, the phone started to charge, after disconnecting from the charger, it worked for a few minutes (there was over 80% of the battery) and suddenly it turned off and would not start anymore.

I will add that I have already replaced the battery and the charging input, unfortunately it did not work, it still does not respond to the charger and attempts to start.

I don't know what I can mention anymore, so I am asking for help.

Thank you very much and have a nice day,

Check that the battery tape is not detached, unhook it and connect it. Also clean the charging socket with something sharp. It is always full of rubbish and blocks the nest

Basis. 3 things you replaced: battery, charging module, usb cable are original ??

The battery strip is definitely plugged in, the charging port is new, so there should be no problems.

Added after 34 [seconds]:

The battery I replaced is original, so are the charger and usb cable.

However, the charging module is a replacement.

Added after 5 [minutes]:

The battery I replaced is original, so are the charger and usb cable.

However, the charging module is a replacement.

Hi. The question is whether the new battery you have installed is working? And I know from experience that it does not necessarily work. Especially if you bought the "original". If possible, use a battery that you are 100% sure is working. A similar situation applies to the dock module that you replaced with a new one. greetings

Looks like a problem with the charging path, usually the Tristar chip is the first to get in the way. It is difficult to correctly diagnose the device without a laboratory power supply.

Try to leave the phone under the charger for the night and see if it will do something, in 5s I had to press on / off plus home (at one time) sometimes after 30 minutes and it fired a few times, but maybe I will try something.

I had 3 iPhone 6s and all of them had a similar problem to yours, and the problem was the unfortunate U2 system ... unfortunately, there are more and more 6, and knowing life in a moment there will be 7 ...

Moment? I've been fixing 7mki for some time :)

Below is the iPhone 7 and the damaged Tristar system, in the 7Plus the system is additionally glued.
