Unfortunately with a battery that size, you would have to sacrifice the svelte figure of your Galaxy Nexus. Based on photos the difference in size is extremely noticeable but we guess that’s the price you’d have to pay for extra juice on your phone. Sadly another price you’d have to pay for the extra juice would be the lack of NFC capabilities should you go with this particular battery, which may or may not matter given how NFC still has yet to see widespread adoption.
No word on how long Seidio’s 3,800mAh battery will last for, but we guess that really depends on what and how you use your phone. If you’re interested in picking up Seidio’s 3,800mAh battery for the Galaxy Nexus, you will be able to order one from their website for $69.95.
