Ive always used different cords for different phones. But some things just dont work. My recent GS4 that I had to put on (cause my other phone broke) takes just about any charger. my Tab 3 on the other hand doesnt work well with HTC. my wifes HTC with original charging cable charges FAST but slow with a samsung charger. All you can do really is play around with options. But you would be better off sticking to OEM stuff especially with an expensive phone like that.
Samsungs new power adaptor supports Quick Charging and can supply up to 9 volts when your battery is low to charge it faster. You can also pick up a car charger that will do the same thing. Well worth it in my opinion. You can take a 20-30 minute drive and pick up 30-40% of battery life under the right conditions.
thanks guys. also asked in the Verizon store, and for what its worth as they are not always the brightest....and even if their wrong, how can you prove they said it....but they said any charger can work with any device.
Sure! they might want you to buy something after it messes up lol but ive only had one instance where a damn windows phone (nokia) micro usb cable mess up the battery life on an htc one m7
