Reviews for Mophie Juice Pack Air for iPhone 4S

I've got a 4S and bought a mophie that worked great. Suddenly it won't charge my iPhone! The phone will charge when I plug the mophie into the power cord, but not when it's unplugged. So I bought a new one--same thing! Went to yet another store and they tried my phone in a mophie there and the very same things happened. The clerk plugged in his 4S and it was fine. So the mophie works, and my phone can get charged THRU the mophie to the power cord, but not BY the mophie, whether its a new or old unit. What gives???

I don't know why everyone's freaking out. Yes, the battery and plugs do ware after a little while. No though, none of the issues addressed here are relevant to my father and step-mother's case. This case has provided average protection, has done its job of emergency-power, and is of decent build. Yes though, the design could see iprovements and the case could be more protective (especially of Digitizer). I'm a 3rd party iPhone Technician and frankly I like this case.

I received the Mophie from a friend as a gift last week. I was concerned that regardless of the protection it afforded my iPhone (more sturdy than my last case) it was bulkier, made it harder to reach the outer buttons, and I wasn't quite convinced it was the battery saviour it said it was. Literally 1 week later (today) whilst trying to plug in my mini usb the port broke and became loose!!! I didn't try to force it in the wrong way, nor did I wriggle, drop or pull anything; it just broke. Now I'm afraid to use this thing as even a plain case, figuring that the initial incentive of battery back-up is useless, but mainly because I figure the dock connector is just as flimsy as the mini usb connector!!! Shoddy, shoddy workmanship, people.

First off, this thing is a lot more bulky and heavy than you might think from the photos. The thin and light iPhone becomes kind of a brick — but that's just going to be true with any external battery case with enough volume to provide a decent charge.

Regarding this case in particular: the buttons on your phone end up very recessed, so you have to really dig to get at them. More fumbling for the volume, for the lock button, for the ringer/silent switch.

They could have just gone the route a lot of thicker cases take and create outer buttons that press through to the buttons on the phone itself — but they didn't.

Otherwise, this case seems (so far) to be very well made and lives up to its power claims.

So I had an earlier version of the Mophie Juice Pac Air for my iPhone 4 that after a year started getting soft. This was to be expected so, I picket up a replacement battery from a local big box store. My first impression with there charging system is that they have went backwards with the fit on the micro-usb connector. The earlier version I had and an acceptable fit, nothing exceptional, but it worked OK. The latest battery I picked up has some serious cable retention problem.

I initially thought I had a unit with a manufacturing defect so I sent it back to Mophie and they promptly sent me a replacement. The replacement battery exhibits the same issue. The problem, as I see it is the micro-usb connecter is too far recessed into the case to make a good contact with the plug. If you use the Mophie supplied cable you should be OK but any other third party/standard micro-usb cable isn't going to fit very well.

So, be careful with what cable you use and be careful with the connector, tyour cables are going to fall out if you move it any (kind of a problem in a car).

You Would Think After Years of Problems They Would Improve the USB Port. I've read many reviews going back years and always the same issue with the USB. Mophie has replaced 4 for me so far. I take good care of my things and this case is no exception. I like the look and feel of the case and battery is great but I'm tired of having to ship mine back every 6-8 months for a replacement. Also, my first replacement they sent me back a used one, not even in original packing. Had to ship that one back too for a NEW case, only to have the same issue with the USB. I'm going to try a different, cheaper brand and see how I do!

I bought 5 of these and they all had problems. It all seemed to stem from the usb port. It was great for the first couple of months but the usb port started to wiggle and and then stop working. I did drop my phone with the case and after that it never seemed to work again. I use it now as a protection for the phone but the battery is unusable.

One was a gift for my brother and he later told me he had an issue with the USB port as well.

Worked great for a few months then suddenly wouldn't charge. I took it back to the store and they replaced it with a new one. That one lasted even less time! Once again it won't charge but it still connects my phone to the computer so it isn't the cable. Crummy product that I would not recommend to anyone.

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.

Everyone is saying the same thing. Great idea, less than acceptable quality. My phone fell from a chair onto a wooden floor and the top piece flew off and cracked in 2 places, making it difficult to put back together.
Battery is average.
$80 is a lot to pay for product that is not ready for the consumer.
I hope the company is reading these reviews and making the adjustments because I'd buy another one if the product was of higher quality.
