Galaxy S6 only turns on when connected to charger.

[Justinkea]

My S6 worked fine for the first month or so when I got it, It started out by just turning off randomly, It went from me doing something on my phone to complete black screen and off. After another month it got to the point where the phone didn't turn on without it being connected to the charger and now it's gotten to the point where it doesn't even turn on when connected to the charger, The screen turns on and then it shows the low battery icon and then turns off even when it's on the charger. I have been attempting to fix it ever since it started happening.

The ic chip that charges the battery is dead or the battery itself
