After getting charging problem on my phone i cut downed my original charger cable into two pieces in anger. But later realized that my charging port was faulty not the cable. But when I went to store I found that C type cable by nokia is too much overpriced. And because of no option I picked random cable for charging. Then I found that cable is working but the speed of charging is too slow and it's happening because of its current capacity and speed. I found app called AMPERE on play store which helps to find which cable is fast/slow or faulty. I will recommend to everyone to try out this app at time of buying any C type or cable for charging. We many times falls in trap of printed speed of cable on box and actually it's something else in reality. I hope this trick will help you in future.
