Default USB Charging 2.0 vs 3.0

Will usb 3.0 charge faster than 2.0? I heard that 3.0 needs more amps, therefore charges faster but it's kind of an emergency and I need to know for sure if it will work this way for android phones.

P.S my sofa cushions keep coming off when i get off it. What do you guys recommend to stop this happening? Squats? Velcro?
