Won´t charge with regular charger. Only fast charger, but dies

Hi.
I got a costumer that has an iPhone 11. The phone came in for a charging port replacement since it wouldn´t charge.

When I got it I tried serveral things:
Wireless charging; Did not work. Battery symbol pops up, but nothing more
Regular charger: Nothing
Fast charger: Did not work, but aslo pops up the battery symbol. Battery symbol goes away, but pops up after 10-20 seconds. Kind of goes in a loop.

Tried a new charging port. Still no luck.
Tried with a new battery (with the new port). The phone turns on, since there is power on the new battery.
So with the new battery:
Charging with regular charger does not work. I´ve tried several chargers.
Wireless charging is indicating charging, but percentage actually drops.
Fast charger works, but after charging for a little while the phone gets hot and dies. Did charge 10 % before it died. Had to disconnect/connect the battery to get it to start again.

What might cause the problem? Maybe a IC-chip?

There are two resistors one on either side of the battery connector I would check these first. You could test with a Tristar tester but I have found on the iPhone 11 the symptoms you are describing especially with the fast charging heat is usually caused by a faulty U3300, L3302 or L3301 I usually replace the three of them to give me piece of mind.

You could try replacing Tristar first it’s up to you.

Thanks for your answer

Could you add photos of the U3300, L3302 and L3301?

Recently started microsoldering, so I’m still in the learning phase?

Tried to look it up on phoneboard

Could be some helpfull practice (IF the costumer let me try tho)

@alex Pic added. I would practise on a donor board before attempting on customers phone. Remember you will have to split the board and be able to re-ball it and reassemble.

@imicrosoldering Thats probably a good idea.

Again, thanks a lot for your help!
