iPhone restarting after plugged in

I have a iPhone 5s that everytime I plug in a charger it says it's charging and shows the Apple logo screen turns on completly and after a couple of seconds of using it it restarts. When it restarts it shows the battery is dead and has to charge. Almost immediately after it turns back on and repeats the process. Screen was replaced and am looking to know if it's a resistor I hit?

I have replaced the battery, charging port, front facing camera, removing the home button, and charging 100%.

It also have destroyed 2 batteries one dropped to .92V and the other won't charging. The phone says it's at 60%.

Both are brand new battery

Answer this question I have this problem too

Is this a good question?

I have installed 3 different batteries non OEM and OEM batteries. There is a hot spot on the board closer to the battery but I do not see any resistors blown or damaged.

Brand new batteries? From a reliable supplier? If you have a universal charger available you could manually boost the batteries back up for further tests.

That being said it sounds like your logic board is shorting out, are there any hotspots on the board? Externally charge up a battery until it is full, and get the Logic board nice and cool. then plug in the battery and lightly feel around and see if there is any spots that get particularly warm.

If you have a board to compare it with check the resistors around the LCD, Digi, and Prox sensor connectors.

Peel back that little black sticker, it is often those that I see people nicking but it is odd that it wouldn't cause a total failure to boot.

This is also an OEM cable and OEM block correct?
