Reviews for Mophie Juice Pack Air for iPhone 4S

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

I had the Mophie Juice Pack Air for my iPod Touch. I immediately went to get the Mophie for my iPhone 4. I absolutely love the look and feel of this case!

I was expecting for the case to give the phone a full charge. To be honest, I was a bit disappointed that I wasn't getting a full charge. Then, I realized if I turned the case on around 30%, I would get an almost full charge.

In conclusion, I really, REALLY like this case. It is by far the best looking charging case for the iPhone 4 out there. It's way past the competition in terms of aesthetics and functionality.

I had the Mophie Air for my 3GS and it slid on and off easily. Not so with this one though. It is easy to put on but difficult to get off. You wonder if you're going to break something in the process of removing it.

If one would leave it on and sync through their PROPRIETARY cable I guess it is ok, but I noticed sitting in the same spot the AT&T reception is worse with it on. I don't recommend

ive had this case for my old att iphone 4 in red and now this one for my verizon iphone 4 and its exactly the same and i love it so much especially because the top is cut off and exposed for any earphones because my monster beats by dre studio cable wont fit in the old case model so this case is awesome and it charges the phones quickly as well

I purchased the juice pack air because I wanted more battery time. I always use a cover on my iPhone, so I thought I'd give it a try.

HOW IT WORKS: The Juice Pack battery is used first when the switch is flipped so you can see the green mark. If you want to use the iPhone battery first and save the Juice Pack battery as back up, flip the switch so you can see the red mark. When your phone battery runs down, flip the switch to see the green mark and the juice pack takes over.

Charging and syncing takes place without removing the Juice Pack. Use the provided USB cable and leave the switch in the "green position".

My internal battery is being used by the time i get home in the evening. The Juice Pack gets me through the day and my internal battery completes the evening. I have plenty of battery power left (about 3/4) left at the end of the day. Not too bulky for what it does! Sleek and protective.

I bought this and instantly fell in love. Not only did this case protect most of my phone; it felt great and wasn't terrible so far as looks go either. It was great with the battery life as well and it definitely is not overrated. I had no problems with until about 3 weeks in when suddenly it wouldn't charge. I tried different chargers and different outlets and nothing would bring my Mophie back to life. All in all I'm sure I got the defective one but Mophie and Apple wouldn't give me a new one. The one bad thing about all the Juice Pack Airs' is that they don't allow you to sync and charge at the same time. The only one that lets you do that is the Juice Pack Pro which is about $20 more. I just picked one up so hopefully it works out this time.

i loved mine i got a blue one and haven't taken it off my iphone since i got it. It works beautifly and it almost charges your whole battery (it charges about 95% of your battery). it also looks really good.one bittersweet side of the case is the bulky-ness of the case, it like it but i doesnt fit in my pant pockets no more..... :/ but otherwise i droped it a couple times and nothin but the case got a little scratch on the back but otherwise.....
I LOVE IT!!!

Purchased for the normal reason, more battery time for video, netflix, hulu, etc or if i forgot to charge it. When i first took it out of the package i was concerned it would break apart to easily. After many months of use it has never been an issue. Then it got dropped and i again was surprised it stayed together. The unit charges great and uses the common usb charge syn cable (small usb). Took it on a 2 week remote camping trip and charged it with a small portable sunlinq solar panel. The battery allows for the higher power required to charge the iphone. So my findings are. 1) it looks a little flimsy but will do its job unless your careless. 2) The ability to use the usb connections is great, dont have to find an oversized apple adapter cable. 3) If you need a way to charge your phone with solar power its perfect and light weight for the backpack. The ability to turn on and off the charging with the toggle makes it the best choice i have found.

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.

It works great but you cant sync it with the case because of the charger thing.
