I'm the type that is searching for the perpetual battery for my iPhone. You know one that is charged at the factory and never needs recharging again. However until that elusive battery is built, I will have to get by with a battery case. I'm looking at this one from Monabello, but I've never heard of this company before, and I'm hoping that someone on this forum has had dealings with them and would care to report. The case can be seen here: http://monabello.com/collections/iphone-6/products/4000mah-power-bank-case-for-iphone-6#.VBGqJ86SxuI thanks.
