Pros Look and feel, adequate battery life
Cons Short life expectancy, Micro USB connection dislodges
Summary The upside: This case has adequate battery life and it's smooth deisgn allows it to slide into and out of your pocket easily. It is also aesthetically pleasing. The battery life indicator and the ability to turn the battery charing on/off are also great features.
The downside: The case doesn't stand the test of time. The micro USB connection gradually sinks into the case making it impossible to charge. This personally happened to me after 5 months of use and no drops. Also, your only access to support is through online forms. There is no confirmation of receipt when you fill out a request and in my experience no response. I would recommend looking at less expensive charging cases unless you feel this case is worth $80 for less than a year of use (less than 6 months for me).
Pros Tight fit, easy to use, good looking, good feel.
Cons None found.
Summary Unless you do not need to extend the life of your case, the Mophie Juice Pack Air is the ultimate iPhone case. At the time of this review, I have had the case one month.
The fit is tight as though the phone and case are one without jiggling or rattling. The top slides off for easy removal to clean your phone or change screen protectors. The volume ringer and power buttons are slight recessed, which I like because it eliminates accidental button pushing.
The extra bulk and weight is a small price to pay for the extended battery life and protection. I have never run out of juice on the heaviest days of usage.
An LCD readout on the bottom of the case displays the extended battery's life with the touch of button. The iPhone battery life display recognizes the extended battery as well. There is an on/off switch for the extended battery, although this is unnecessary, as the extended battery does not kick in until the primary battery is drained.
Charging and synching are easy with the included USB cable that hooks up to your laptop, desktop, or iPhone wall outlet adapter. Both batteries are charged while connected and there is overcharging protection wired in.
The case has a very nice feel with smooth aluminum edge, soft velvet feel on the back, and it looks great. When I stopped in a Verizon store, the manager flipped and did cartwheels (joking).
Full 5 Stars for quality and value.
