2 years ago we bought a phone at future shop, the battery drains easily and they said that is normal because of the big screen, a new galaxy that I need to charge every 4 hours even though I am not using it.
But the worse part is they gave us warranty that they did not ask and it is written as a code, who would know a number code any ways.
I am not aware they they really cheat, I bought a laptop, and they gave me a charger made in china different from the brand of the laptop, which I am became aware when it got so hot when I am charging.
Now I have to go back in the store on the weekend, I do not know what are they going to tell me.
I hope they will change it because it might cause a fire, the charger went really really hot and I just plugged it in an hour ago.
