An Even Beefier Battery for the LTE Nexus?

Just gave up my EVO4G and my expired Sprint Contract for the Nexus. No regrets....

BUT... I was COMPLETELY spoiled by my 3500MAH battery on my EVO. Never had an issue with the bigger (backside). Verizons LTE network eats the Galaxy Nexus battery alive.. Lol it stands no chance!!! The Funny thing is it's the same usage I used to get when I orginally got my EVO with the 1500Mah... I don't want to go back to those days. I'm Spoiled by Seidio Is there anyway we'll see a much beefier third party battery from Seidio or any other 3rd party that will include NFC capabilities? Or do I just need a 2nd... And Thrid battery? lol
