am really runing mad here (especially now that am looking for money to do something more important than buying phone) it started this week, when i plug in charger in my Infinix hot3 it will indicate to be charging but it doesn't increase in percentage, so i took it to one phone repairer the man said is charging pot problem, but after he had changed it (charging pot) the problem still persist, it doesn't charge fast as it used to, i ve been charging it for 7hours now is only 50% ve got (what i noticed is that it doesn't charge beyond 79%) tested it with different fast chargers is same slow charging problem, am kinda confuse whether the problem is from battery or what,

help if you can
