Sure 4G sounds great and all, but once we really get down to it, is it something that will really make a difference in what we do on our phones. For the most part a large portion of the population uses the data on their phones to access email, Twitter, Facebook, and maybe Flickr. Taking all of these into account will these supposedly wi-fi equivalent speeds really speed up what you are doing on your phone. The answer is that it probably will not make much of a difference unless you do more demanding tasks such as video calling, uploading mb of pictures, or downloading large files for work. Even so 4G is not necessarily the battery saver of data. When your 4G is on it will simply drain your battery to death in a very short amount of time.
