Reviews for Mophie Juice Pack Air for iPhone 4S

I was totally impressed by the extended battery life in something so elegant. In the first week I dropped it! I have the white model so it may be more prone to sliding out of one's hand or off the car seat but it protected my 4s perfectly. Only one problem - now it won't charge. Other's have noted that if you push the micro usb in a certain way it might work. Apparently not if it lands on that corner.

Mophie would not honor a warranty claim as it "is not a manufacturing defect". Well, don't by the juice pack if you are hoping that, while it may protect your phone, it is not durable enough to protect itself.

Using new iPhone 4s 64gb and it doesn't sync with iTunes when plugged in through the case like it says it does. Battery life isn't bad but for 80$ and advertised to work with 4s I am expecting it to work

From the first day the charger connection seemed a weak point.
After time the connection would literally fall out by itself.
Now after all the frustration I am left with a spare that has no power whatsoever.

I love the idea of having an extra battery. I liked the look and feel of this product, but unfortunately Mophie needs to redesign it. First of all the camera does not work well at night in this case. The flash puts a glare on the photos and the photos come out blurry. I had to take my iPhone out of the case to use the camera with the flash. I had problems with the charging port. I had trouble keeping the connection and sometimes had to tape it to hold the connection. My Mophie started to give me problems 6 months into use and just two weeks over a year of having it, it stopped working all together. Its to expensive for all the problems!.

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.

Ihave owned several Mophie Juice Packs and have had quality problems with everyone. The last worked great for about 8 months then wouldn't charge my phone. For this reason I don't recommend this product.

It worked well in the first few months. It definitely adds battery life. The case protects the phone from drops but sacrifices itself in doing so. It literally comes apart at the seams after a small drop. I have extended its life about 6 weeks with superglue but now it has come totally apart. It lasted about 5 months. Wouldn't recommend.

I love everything about this product except the poorly made usb charging port. I went to charge it today and the port itself came loose and now will not work. I am still within my warranty period and have opened a case with Mophie to get it replaced. I will let everyone know how it goes.

FWIW, I have only ever used the usb cable that came with it and use my apple wall socket that came with my phone and I am very good about being gentle with all my electronics as I am kind of OCD about my stuff.

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.

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).
