iPhone 7 not charging after two battery and charging port changes

Hello,

After a screen replacement, the device did not charge properly and it was stuck at 3% with charging symbol so I replaced the charging port and got a new battery while I was at it.

After that, the device only shows 1% without a charging symbol even when plugged it.

I thought the charging port may be faulty since I got I got the charging port from the same company that provided me two DoA screens so I went ahead and got another charging port from a different company and changed it again.

I still have the same issue where the phone only shows 1%, no charging symbol, and doesn’t charge . The phone also has long boot issue as well after the initial screen replacement.

What could it be?

What iOS is it running can you get it on to see?

It should be running the latest iOS as of end of July.

I haven't used the phone since then lol.

Been using my friend's iPhone 6.

Does it sync to itunes but not charge?

When disconnecting the battery there are tiny components by the battery. Have someone who microsolders check near the connection.

Also when they are checking near the connection they may be able to rule out the charging chip commonly known as the u2 IC
