Phone only charges when screen is off, died completely.

For about a week my phone has only charged with the screen on, a small inconvenience but i just left the screen on when it charged. Unfortunately i did not get it plugged in and it died completely and i cannot get it to charge. I cant get into recovery mode but i can get it to say powered by android, and show the 0% battery when i first plug it in. i was able to get it to 3% by holding my cable down . i turned it on to let it charge but it did not continue charging. Advice? the phone is revvl plus but its manufactured by coolpad

Try another charger, try another cable. Inspect the charging port for looseness, wear and tear, dirt, fluff etc. Use a multimeter to check the voltage coming out of the charging unit to make sure the voltage level is correct.

the charger works on other phones, if necessary where would i buy a replacement board? There is copper exposed exposed on the bit in the charging port.
