iPhone 6 won't turn on after battery replacement

I got a new battery replaced on my iphone 6

Then I got back home and put the phone to charge then it charged up to 76% then I removed the charger. Then I used it till it died (till it came to 0%)

It was night then I plugged my phone to the charger and slept I heard the sound of the charging which comes from the phone once you plug it

Then I left the phone to charge and then got up in the morning and my phone was dead

I tried putting it back on charge it didn't work

Was it the battery that caused this error?

Please answer quickly
