Galaxy S7 Slow Charging [SOLVED]

[davidkoplik]

Hi,
so I am charging my Galaxy S7 (International Exynos version) for third time, and the charging takes about 5.5 hours (I do not use FastCharging). Is that normal that it takes so long? And, is it recommended to use FastCharging? Some people said it can affect the battery life... Well, my main question is:

Is it normal that regular charging through MacBook Pro with Samsung's original cable takes 5.5 hours to charge from 20% to 100%?

Charging though macbook pro...
That already explain why it is charging slowly. Computer usb port power output is very low compare to wall charger.

xD Yeah, not a good question... I tried the USB, and it charges a lot faster...

Charge from a wall socket.

The included Fast Charger can output up to 2 amps. The maximum that a USB port can output is 0.5 amps. That alone means the best you can do with a computer USB port is 4 times as long as with the included charger. Note the 0.5 amps limit on a PC may be shared among several physical USB ports so any particular USB port may have less than that 0.5 amp available. Also if the phone is on during charging then that will slow down the charge rate.
