I apologize if this topic has been covered before. I understand there is a search function on this site, but it is not working out to well for me. I was wondering if anyone could share their first hand experience with their battery options for the gs4. I'm planning on switching to the GS4 soon and wanted to get some opinions on what battery options people are using. If there are any complications with NFC/S-beam or if they can still use wireless charging feature. So if you could post how well the battery options you chose it would be greatly appreciated. Maybe like what you chose and maybe a case that went with it or what you tried and didn't like. Thanks in advanced!
