Companies have been saying that by the end of 2012, USB 3.0 will be implemented in your smartphones and tablet PCs which will allow speedier data transfer than the current USB 2.0 standard.
USB 3.0 allows for data transfer rates of around 625 MB/s, which is 10 times faster than USB 2.0, whose maximum data transfer speed is 60 MB/s. The USB 3.0 transfer speed on mobile devices won’t be that fast, but it will be much faster than now.
Devices using USB 3.0 will also take a lot shorter of time to fully charge.
USB Implementers Forum also said it aims to reduce the size of USB 3.0 ports on laptops, as it’s becoming a limiting factor in laptop thinness.
