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???

Why don't Morphie address the USB issue, my second USB socket as gone the same way as the first, not working. I treated this one with kid gloves and it's lasted less time than the first! I bought it from Apple so hope they will replace it, but after this one gives up (which reading these reviews, it will) unfortunately I think that's it for me and Morphie. Such a shame as it is very good in every other way and has got me out of problems on those long days when I fly. Also it's really good in the hand and I think improves the look of my iPhone.

The product does what it is designed to do but when mine is in standby mode it mutes my phone. I had the same problem with the Mophie I had for a month and the Apple store replaced it; now this one is doing the same thing !???

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've gotten my first mophie juice pack air for my iPhone 4 and it was working great for at least 4 months or so but when I dropped it a couple of times or accidentally hit something with it, for some reason the usb port on my case came loose and it just made it harder for me to recharge the case even though my usb cord was working just fine. Other words it'll work for awhile and once it gets dropped a couple of times that's when it'll stop working. I did of course got myself a second one when I realized I had a one year warranty with the company but of course I was dead wrong when I thought it'll be just fine and turns out the usb port came loose again. I'm never going to get this product again if they keep giving me a case with a loose usb port even though the usb cord works perfectly fine. I think they need to figure out a way to make the usb port not so loose or at least make one that has a reliable usb port that's not so small or make it similar to the one that's usually on the phone already. The product is okay but this is the second time I'm having the same problems and I really do like it when it charges my phone plus I don't have to keep recharging my phone once my battery is low.

I have used the Mophie Plus for a few weeks, following the recommendation that I let the phone battery run down before turning on the pack. My iPhone battery now drains much faster when I'm not using the pack. After five standby hours overnight, the battery had gone from 100% to 60%. Before the Mophie, it would have still been over 90% full. Maybe I just got a defective one?

The Juice Pack cover is great, in that it looks good, feels pretty sturdy, and ideal for feeding the phone extra power when it needs it.

However, I have recently been experiencing a problem where the power cable gets loose very easily, and constantly disconnects itself. From day one the power plug looked like it didnt quite enter the socket as deeply as it needs to. Over time, it seems to have got looser, and as a result now disconnects a lot.

I think that part needs re-engineered. The power plug needs to sit firmly in the socket, and it doesnt. FIx that, and it'll be an excellent utility.

As with most other users I loved Juice Pack Air's extended battery life as I'm always on the go, but one day the mini USB port at the bottom of the battery pack couldn't hold the cable, and having to sort of pushing the cable into that plug with my one hand in order to charge and typing this with my other really annoys me.

First, of all let me start off by saying this product is worth its weight in gold. It really keeps your phone charge for a long time. The Juice Pack is really sturdy and protects the phone very well, but I'm still giving it three stars. Why? because it's really difficult to install and it's really difficult to remove from its case! otherwise this item is perfect for the IPhone and its battery. I would highly
recommend this product hands down.

I bought this juice pack just 14 days ago. A couple of days ago I noticed my phone was dead even though it was plugged into my iMac usb. I figured ok I must have done something wrong. Now today I plugged it in and noticed that it is not charging at all via the cable plugged into the juice pack. Today my return expires I just called the apple store and even though I can"t get there at the twelfth hour I was told bring it in tomorrow for a replacement. After reading one review here it may seem that the charge pins broke or something like that. I will give a second pack a try because this pack did work well when it worked.
