iPhone 5 Battery Case Recommendation
I'm looking at purchasing a battery case for my iPhone 5.
I know most (all?) are two-piece cases. I've had bad luck with two-piece cases in the past. They seem to loosen up over time and loose their effectiveness.
Any recommendations? Capacity isn't a priority for me. My biggest concern is durability and sturdiness.
Mophie?
Lenmar Meridian?
Powerskin looks nice, but I've never seen one in person.
iBattz has removable batteries so you can carry an extra with you. Sounds nice, but I don't like additional moving parts that can be lost or fail.
