Reviews for Mophie Juice Pack Air for iPhone 4S

I used the Juice Pack (JP) as my travel "lifesaver" for the past 7 months. Up until this week it served every need as expected and more. I dropped my iPhone 4 for the first time on a trip this July 11'. The JP hit on the corner that the power cord gets inserted into, still leaving the phone in perfect condition...but the impact killed the the power port. Looking at the JP it still looks like it's in mint condition until you attempt to charge it and realize the port closed from impact and very careful attempts to pry it open failed. Though it no longer can be used as a charger, it certainly protects the phone.

This is the second Mophie I bought. I was really rough on the first one and it died.

My iPhone 4 remains pristine.

This one is so rugged, even I can't break it. I was snowboarding with this in my jacket pocket and landed on it in the middle of an icy half-pipe. It nearly broke my ribs.

My iPhone 4 remains pristine.

I will always protect my investment with a Mophie powered case. Best accessory ever.

I recently bought 5 of these cases for members in my family. For about a 2 weeks the cases were amazing now they won't charge at all. It's definitely a port issue but buying this product was definitely a waste of my money. It would be great if they could fix this port issue but idk if I'd be willing to buy this product again.

It does exactly what it's meant to do. I personally like the slightly larger size than the iPhone itself, it makes it little more comfortable to hold. After about 16 hours of constant use today I still have 52% battery left. That includes all location services on, using gps for turn by turn directions (Motion X), browsing internet, retrieving e-mails every 15 mins, Bluetooth on and playing music while driving, making calls, and I spent most of my day in a bad reception area.

It does what it says. The case is well designed, seems rugged, and it easily slides into a pants pocket. Of course it adds bulk and weight -- it's a battery. But they did it well.

The rather serious design flaw is the USB plug. If you look carefully at the product picture you'll see that the plug is recessed on the lower-right corner. In that location the curve of the case partially blocks the plug. The result is that it's very hard to fully insert a plug, and it easily and frequently comes unplugged. It's frustrating and sometimes you'll think you're charging, but discover the plug wasn't (or couldn't be) inserted deeply enough.

I bought mophi on September 2011 I really love it. The best part is that it truly protects the phone. It's a very durable case. The only problem I have with it is that the plug may not last more than a few months. The plug became loose...though the case was still working just fine. I contacted mophie a few days ago I hope they give me a solution. Great product, but it has its flaws.

Debated, debated, and furthermore debated. FINALLY, decided to pick up one of these bad boys and boy was I dissapointed. First I'll give the pro's, because unlike many, I like to keep a good balanced review. The "on Demand" battery portion is AWESOME. Being able to juice the phone when need be was the deal breaker for purchase. It powers the phone very fast and you can EASILY go a day without charging an iphone4 / S. Something I couldnt fathom before purchasing. Also, rubberized material does cover your phone.

Ok, now to the bad ! For some reason my top kept unsnapping when I would pull the thing outta my pocket. Thus, I dropped my phone a few times or fumbled the thing upon catching it. Its still rather bulky given "slim" profile. I will say, please the good with the bad here because to get you have to give a little which will be form factor for more juice. Last, it takes a micro usb port which broke off only 5 days after I purchased. Not the business if I might say.

Mophie generally makes great products- my juice pack for the 3g lasted longer than the phone itself. the model for iPhone 4 has some issues though

i know some folks that have had zero issues but my wife and I both had problems

I had to return mine after 4 months- it actually "broke" the accelerometer on my phone. I would lose the ability to go inot landscape model and only a hard reset of thephone restored the ability. had to return the mophie and exchange my phone under Apple Care.

My wife- hers just could not hold a charge after about 7 months.

Again- good product and company- just be very mindful of performance

it also does affect signal strength.

This product was exactly what I needed but did not survive ordinary use for 6 months. Took it back since charging port would not hold on to USB jack. It was replaced by Sprint (where I bought it) but the same thing happened to the second one, only in shorter time. This is not a product that should be associated with Apple as quality is very poor. I will try some other brand next.

I can tell you one thing about this product. It takes a beating! I laid my iphone on top of my car, forgot I put it there and drove off. I heard a thump and looked at the speedometer, glanced in the rear view mirror and say the top part of the case bouncing down the road. I was doing 42 miles an hour and stopped as fast as I could. I put my hazards on and started walking around to find my phone. While searching I was questioning how bad it was going to be, it was Sunday, need my phone, no Apple Store around, cursing myself and finally found it face down. I hesitated as I didn't want to see the broken glass all over the place. To my amazement the phone had a couple of small scratches on the metal band and just a few hairline scratches around the speaker at the top. The Mophie case had gouges about 1/6" deep all over it. The case worked and saved my phone. The Mophie still charges and my phone works fine.
If I would have had a screen protector on it I think you would never be able to tell that my iphone slid and bounced down a country road at over 40 mph. I am sold on Mophies!!!
