I had the same problem. I changed the charging port. But it still didn't work. I bought it from Aliexpress. My phone is LG v50. What other problem could there be?
@@asharyaseen3923 check your USB cable. Believe it or not sometimes they get worn out cahrge your phone slowly. I had the same issue with my LG v60 the charger port was good it would snap in and lock in place. If your USB cable feels loose then you got some dust or something inside it. The wall charger was great. Until swapped to a type USB cable that was 3.0 right away the charging speed work all over again. 1hr 15 minutes now before it use to be 2hr 28min then it turn into 6hr 48min.
