Slow charging

[GiiRafFee]

My phone usually used to take 120-130 minutes to full charge I.e., from 0-100%. 

But since yesterday I've noticed a slow charge so I thought I will give it a check and I plugged in the charger when my battery was 41%.

It gave me an estimation of 1 hour 14 minutes to full charge. But I plugged in the charger for 40 minutes then it was only 60% charged and was giving me an estimation of 53 minutes more to full charge. Why? There was no power cut in between. 

I faced it 2 weeks ago so I had to reset my device, after factory data reset it was normal again. It was just 120-130 minutes full charge.

And now again I'm facing this issue. 

Is anyone facing this issue ?
