I bought my galaxy nexus about a year ago cash so that I could keep my Verizon LTE unlimited. As we all know, the battery life sucks on this phone. I have two of the extended factory batteries, but each would only last about two hours each(I use my phone quite a lot!). So I found this aftermarket battery on Amazon: [180 days warranty] ZeroLemon Samsung Galaxy Nexus 5900mAh Extended Battery + Black Full Edge Wrap TPU Case with 180 days Zero Lemon Guarantee Warranty. Yes yo read that right! 5900mah! I have used this puppy for the last three days and these are my results: On the first day it lasted about 14hrs with all the radios on, constant use(7hrs of screen time on) emails, web browsing, you name it! I unplugged my phone yesterday around 7am and came home at around 11:35pm with 14% of battery left( I use it at work to listen to pandora, web browsing once in a while, you tube videos during my lunch). I think that the screen on time was about 6hrs+ on auto brightness. I'm blown away by this battery and I'm keeping my phone for at least another year, since the battery life was the only thing that was really bothering me! Yes, it makes the phone thicker and heavier, but it still fits in my jeans pockets( I don't wear skinny jeans) that are normal jeans. No more carrying a charger and extra battery! I highly recommend this battery if you have a Verizon Galaxy Nexus and want to keep it for a while but hate the battery life. The case that you have to put on the phone is actually nice and doesn't fell cheap.
