Hi there just been using my exynos note 4 for a few days now...love it. And the battery is good for a stock. But I am now investigating if there is any good other options and if anyone's found any good ones? Zero lemon looks like a brick so really don't want that. Hyperion I can't buy as I'm not in the US . I was wondering also if any of the bigger batteries fitted in the nice cases like spigens? That type of thing? I know the fast charge is a nice feature too maybe I could even use that suppose but a little more juice would be great!
