DNA has 2020mah and it gets similar battery life to GS3 with regular battery. But I like to point out this.

This is mind blowing battery for Note 2! Almost double of Maxx HD. I think samsung deserves a credit for sticking with removable battery design while almost everyone else with going fixed battery.
