Most of the official cases don't come out till next month. I have just got an external battery for now till these cases come out. The LTE is a real battery killer.
yeah,LTE consume my battery rapidly,even can't last for one day ,I find some battery case,does it really work? http://www.iphone-5case.com/iphone-5-accessories-iphone-5-batteries-c-6_8.html
Saw a deal come up in Google Offers for this battery case today http://www.dealsondirect.com/collections/iphone-5/products/iphone-5-lightning-battery-case Figured I wuld give it a try (google offer is $29 instead of $80)
Yeah I love my iPhone 5 but on the days I use it hard the battery is no bueno. I pretty much used the Juice Pack Plus exclusively on my iPhone 4 for over a year and will probably be heading back to one of their cases once they release.
