iPhone 5s not starting or charging, tried new battery no difference

Hi a friend of mine told me if i can have a look into his iphone 5s, the phone have had a cracked screen but was working and just before he gave it to me died and it never turned on again.

I have tried re starting, dfu, disconnect the battery, i have tested the voltage of the battery and it was 0v, I replaced the battery for a new one no change whatsoever.

It could be the motherboard?

Hi, more than likely Tristar/U2 IC chip issue, if a cheap cable has been used this is more than likely your problem, and requires micro soldering.

No power with new battery could be PMIC (power management)

The thing is that the phone doesn't start with a fully charged battery either, is that normal with the ic chip fried?

Not usually no, could be PMIC

If the phone does not turn on with a known working good fully charged battery then it's probably not the charging IC and is more like the power management ic.
