So with smartphones getting increasingly powerful and the batteries improving at a slower rate, the need for an external battery has arisen. Are there any particular batteries that are better than others? Just for reference, this would be for a Droid 4 (not mine, it will be a gift). I can't remember if there has been a Battlemodo of external cell batteries or not, but it would definitely be a good comparison someday.
