It's dies after 75%

Mi Problema

75, 60, 50, anything below 80% the phone would die and I'm left with no phone for the rest of the day. I had someone replace it with a new battery but it was still the same.

Mi Solución

Repair want pretty easy but I had to YouTube it first to be sure i know which part to take off first and where

Mi Consejo

Just follow the instructions it's pretty easy
