Reviews for Mophie Juice Pack Air for iPhone 4S

I've been a mophie juice pack user since the iPhone 3G and the product has only gotten better.

The Juice Pack Air is intended to charge a dead battery up to approximately 70% full and it delivers again and again. If you're looking for a full charge, check out the Juice Pack Plus as it's marginally thicker and delivers a complete full charge.

The Juice Pack Air is stylish with the two-tone colors (though I wish it came entirely in black) and functional at the same time. My only complaints are that the volume and sleep buttons were pass through like the Juice Pack Plus and that the LED lights would shut off after fully charged. If you have larger fingers the buttons can be hard to push with the opening on the Juice Pack Air and the LED lights can be very bright when they are all illuminated in a dark room.

I am currently on my third replacement mophie now. Why you ask? The charge port for all these iphone 4 mophie chargers breaks if you try to move the phone while it's charging. The connector is just way too flimsy. If they fix that then the charger would be perfect. I am in no way rough with my phone but the design of the charge port is horrendous. As long as you don't move your phone while it is charging you will be fine. To be honest I still use it (the third one) but I cannot disturb its meditative charging process or it will banish me to the land of no charge.

The apple store version of the juicepack air is newer, and is more compatible with other devices. The top is wide open, the bottom comes off to expose the iPod port. If you buy the juicepack air anywhere else it has the same "almost doubles your battery life" capability, but the other model is a little bulkier, less friendly to large headphones, doesn't easily let you access the ipod port, but seems to be tougher and protects the phone a little more.

I prefer USB micro over the iPhone/iPod port anyway, so I never remove the case. iTunes syncs just fine, and the charger is interchangeable with my son's android phone. Supposedly the wireless performance is affected by the case, I haven't seen any difference.

While this device is great for having extra battery juice, what the other reviewers say is absolutely true. This product breaks EASILY. Myself and two others have within a week of buying one, also damaged it -- One of us have already broken the charging port (as indicated by others to be fragile) and two of us have dropped the case and have cracks in it now. Thus, if you think your case will survive a fall, rest assured. It WILL NOT. Lastly, this device is uncomfortable to hold while plugged in because of the location of the power port. Mophie needs to go back to the drawing board.

Awarding 1 star for the battery life, but really can't give any more due to the obviously faulty design: not drop resistant, power port is fragile, and the issue with holding the device while plugged in...

Posting this review for black, white, and red products as they are all the same.

I have had three (bought two, Mophie replaced one). Each one is more useless than the last one.
The problem is simple, the plug is not stable and once you plug it and unplug it several times, it becomes loose and will no longer take a charge.
I have complained directly to Mophie, am I will wait for a better design before I buy a new one.

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.

I've always loved Mophie products, but this one has a huge design flaw when it comes to the 4S. Don't get me wrong it holds the charge and is fabulous for when you need that extra battery life. The problem is that you can't get it off your phone when you are done. I don't want that bulky case on my phone 24/7, just when I need it and you can't get it off. I literally had to pry my phone out praying I wouldn't break anything using two dulled knives to try and break the seal. It is ridiculous.

even though it charges my iPhone up to 80% it is extremelly difficult to take the phone out of the "case"- specially if you're a woman and want to keep your nails pretty :)
The previous model (3Gs) worked better in that way.

My friend had this Mophie Juice Pack for his iPhone 4 and he swears by it. Soo.. when I upgraded to the 4s a few days ago.. I decided to get this case. I realize I've only had it for a few days.. but I'm very impressed with it.

First and foremost.. it's a really solid case. It fits my iPhone 4s like a glove. It adds a little weight to the phone.. and I kinda like that. It makes the phone feel more "solid". It also makes it more comfortable to hold.. and the "rubber like" back makes it less slippery to hold.

The cut out at the top makes the ports accessible for earbuds etc. And the batter life seems to be pretty good. It's definitely a major improvement on the internal battery life.

I usually start my day around 8:00AM.. and I consider myself a fairly heavy iPhone user. Constantly checking email.. Facebook.. browsing the web.. texting.. and talking on the phone. I work outdoors and on most days I listen to music as well. I also browse videos on YouTube occasionally. So far.. I've managed to get thru my entire day without even coming close to a dead phone. By 8:00PM... the Mophie battery is drained.. but I still have around 70-75% battery life left on the iPhone's internal battery. This is far better then it is without the Mophie.. when my battery would be at 35-40% by 3:00-4:00PM.

I realize it's an expensive "case"... but it's more then a case. It's a battery and a case. To me.. the Mophie has definitely been worth the money~

This works as it should. It recharges my phone up to 80% so more time for games, pandora and calls.

Only con after a while the USB cable will break. If your careful it won't but if not find a universial USB cable, like the ones most android phones use.
