One thing about my observation toward my device charging.

Ok, phone will charge like normal for 3 times. At the 4th time, phone still charge and will take 5~6 hours to fully charge the phone and at the 5th time, it will stop detect charger or plugged in cable and phone had to be restart in order to work. AND the whole process repeat again from 1st to 5th charge.

I'm using original charger and i've already reset phone once thinking it is software defect. Any opinion from u guys about this? 

Help are much appreciated guys & happy CNY.
