Samsung have released an extended battery for the US Galaxy Nexus. I know the US and EU versions have a slightly different shape, so was wondering if this extended battery would fit my UK Galaxy Nexus? Or if there's a version which would fit?
Engadget has a great comparison shot of the battery differences between the HSPA+ and LTE versions in their review of the Verizon (LTE) Galaxy Nexus. The short answers seems to be 'no'; the link you provided is to an extended battery for the LTE Galaxy Nexus and therefore wouldn't be compatible with your HSPA+ version.
