Samsung galaxy s6 edge charging problem?

[AC Question]

I got it like 2 months ago... i think it started yesterday but i've noticed that the fast charging brick/cable has a problem. When i charge my phone, it says that the cable im using isnt the fast one and it also says that i need to wait 6 hours to load from 10% to 100%... it used to be 1.30-2h what happened? Anyone else has the same problem?
