One of the more interesting accessories for the upcoming Verizon Samsung Galaxy Nexus is the extended battery. This battery is a decent 2100 mAh variety, which gives the phone an additional 13% power boost. That should be enough for a couple hours more daily usage. What's really impressive about this larger battery is that it isn't really that much larger, physically. It does include a new cover, but it only adds a little bit of thickness to the phone. This is a large improvement from typical extended batteries that turn your phone into a retro 80's style brick.
