Hi, i had been charging my samsung j5 2016 with the cable that came with the phone box from samsung (original cable) and it was doing great since i bought it (bought it in jan 2017) but from last 2 weeks its not charging as fast as it was doing normally, yesterday it put it on charge at 52% and after like 45 minutes it was at 58%. Then i tried different chargers and its still same (i have tried 3 other chargers) I also tried to put it with lapto but its even slow with laptop. Now the plot twist is this morning i put it on charging and it got full from 45% to 100% just in 1.5 hours. but now again in evening it took 1 hour to charge just 20%. Now i don't know what should i do with it? please someone can help me in this thanks in advance.
PS: i didn't downloaded the latest update sent by samsung but i hope that is not the problem?
