UK Note Battery in US Note Phone?

[SebastianNap]

Doesn't the Galaxy Note in the UK supposedly have a longer battery life than the US Note? If so, is it the batteries or the device? I have the US Note in NYC with AT&T but I heard the UK Note has better battery life. Can I use the UK note on AT&T and still have 4G without rooting or do I just have to unlock?:-! Or can I just use the UK battery in the US version?

The uk version will not get lte in the us.

Batteries are cheap.
