This is good news, finally saw this release go through and now sharing with you, guys!
Mugen released 3 batteries for Galaxy Nexus:
Verizon Galaxy Nexus 2000mah extended battery OEM size
GSM Galaxy Nexus i9250 2000mAh extended battery OEM size
GSM Galaxy Nexus i9250 4000mAh extended battery with back door
This phone was in big need for a proper battery so I'd love to see someone review it
