Battery Full Hyperion 5200mAh Extended Battery For Galaxy S4


Does anyone have any experience with Hyperion extended batteries for the Galaxy S4?

I'm going to be ordering one soon but thought I should ask about the performance and experience by people who may have used it. It says that the battery now has NFC, can anyone using it confirm if it is true?

The battery has positive reviews on Amazon. Can anyone also tell how fat does the S4 get when used with the battery? Also what timings are you guys getting with the battery? Is an external case needed to avoid any ugliness or anything?

All this and if you have anything to else to add would be of great help.
