J7 2016 charging issue.

[HariPrashanth]

Hi, This is Prashanth and I've been using j7 2016 model running on nougat for the past 3 years. I use Samsung charger that came with the box. Since yesterday, my phone's charging speed has reduced. It takes 4 hours to reach 60% from 10%. Same scenario even in safe mode. Last time when i had slow charging issue, I brought a new charging cable from Samsung service centre and the issue had been resolved.
 I have not updated my device to Oreo via FOTA update as the previous update ruined my battery life. I also checked my phone's charging speed with another samsung charger and the charge speed is absolutely fine. Problem persists only with my charger. So please guide me if I've got to buy another charger or what i should do.
 
My phone does not heat up at all. Temperature of phone while charging is normal. 

Thanks in advance,
Prashanth

lithium ion battery tends to degrade over time your device is now 3 years old.

fully discharge battery and charge without turning on till 100%. just suggested I'm not sure.

Go to Samsung care, they will tell you whether charger is faulty or cable is at fault. In my case cable was at fault, after changing cable it's all set

Change the cable only.
same happened with me.
Install ampere app from playstore and check battery amps.
if it is below 1400 then try with another cable.
Try using any quality cable not a cheap one.

I got this result with 2 different cables. Is it fine?
Please reply if possible.
