Seidio's 3800mAh battery turns the Galaxy Nexus into Quasimodo31
The juicer is with the astonishing 3800mAh capacity, ready to power your device for more than a day of heavy usage. That is more than even the one on the Motorola DROID RAZR MAXX, and TI's OMAP chips are known for their well-optimized power consumption anyway.
The only thing you have to part with, besides $69.95 for Seidio's 3800mAh battery, is your pride. When you tack the fat Li-Ion unit, a hunch forms on the back of your device, so it won't be as pretty as its maker intended, but beauty is in the eye of the beholder. Oh, you also lose the NFC connectivity, in case you ever used it.
