iPhone 6 Plus Won't Turn On After Battery Replacement

I bought an iPhone 6 battery from this website and replaced the battery of an iPhone 6 Plus that I have. After I replaced the battery, the phone turned on for like 10 seconds, the screen was white with the apple logo in the middle. Then it turned off and never turned on again. I thought that maybe it was the battery that was faulty so I bought a new battery. I tested the new battery and still the phone won't turn on.

I am using an original iPhone charger and the phone doesn't get warm when I plug it in. Could it be something with the motherboard?

Answer this question I have this problem too

Is this a good question?

Just for clarification, you bought a iPhone 6 or 6 plus battery?

Because you can't fit 6 battery in a 6 plus and vice versa.

Is it still able to display apple logo at the moment?

Can you check if apple logo goes Off immediately on charging cable unplug when it displays apple logo?

And when you leave it on apple logo, does the phone shut off or go to a lit up blank screen which it would mean it's booting into DFU mode.

You can verify if the phone is in DFU mode by using 3utools or iTunes.

What was wrong with the old battery?

Was it that the phone didn't charge once the battery went flat?

The phone does nothing. It hasn't turned on the apple logo again at all. Nothing comes up, it doesn't turn on. iTunes is unable to recognize it and my computer doesn't recognize it either.

I changed the old battery because I would leave it plugged in for hours and the phone would remain at 1%. Sometimes in like 4 minutes it would charge up to 100% and then once I unplugged it and began to use it, the battery would go down to 2% immediately. When the battery would die completely, it would take a while for it to turn back up again. Once I thought it went dead, so I began to press the on/off button a lot and the home button and it turned on. I've tried doing it with the new battery but nothing happens.

Could be your "New" batteries needed charged a bit and your Charging port is bad or "Clogged". Check and clean the charging port out to make sure it is not clogged up with lint, etc... Then, if it still doesn't work or charge... it could be you have a bad U2 (Tristar) charging USB IC and would require Micro Soldering to put on a new one (1610a2).

You can also unplug your battery and test the battery and the logic board connector to see if your battery is good and charged enough to power up the phone and also that the charging circuit at the connector is actually putting out a charging voltage.
