Mophie vs. Incase
Written by RR from Germantown
May 3, 2009
I purchased both the Mophie Juice Pack Air (MJPA) and the Incase Power Slider (IPS) at my local Apple store with the intention of comparing them and returning one utilizing the 14-day return policy. The Mophie is the superior product in my opinion and I returned the Incase and here is why.
In terms of performance, the MJPA, was the clear winner (and isn't that what its about?). Although the MJPA has a 1200mAh battery as opposed to Incase's 1300mAh, the ability to turn on and off the recharge on the MJPA seems to actually provide more recharge due to a lack of continuous power transfer.
I noticed no degradation in speaker volume or clarity using the MJPA. The IPS muffled the speaker considerably. Similarly, the microphone is unencumbered by the MJPA but is grossly affected by the IPS. I made a few calls using speakerphone with both cases. My wife noticed no difference on the other end while using the MJPA but heard an "annoying echo" along with a loss of volume using the IPS.
Both cases add considerable bulk to the phone, however, the MJPA is smaller than the IPS.
This is purely subjective, but I feel the IPS beats the MJPA in aesthetics. I greatly prefer Incase's matte rubber finish. It has a much better grip and doesn't show all of the fingerprints and scratches that Mophie's smooth glossy finish can't help but show. It also has more front coverage to protect the shiny metal edge of the iPhone. I also prefer Incase's more discrete battery indicator on the back of the case.
With all of that said it comes down to this: I like the idea of both cases because they provide protection and about twice the battery life BUT, in shear performance the Mophie Juice Pack Air is clearly the superior product. It is smaller. It doesn't have any speaker or microphone problems and it provides slightly better battery performance. …More1037 of 1072 people found this useful

Finally!!!
Written by EG from Bloomfield
May 1, 2009
I've been using this for a few days now and I'm pretty happy with its performance so far. The Air adds more than 8 hours to my phone's usage, which is pretty good since I've been purposely using the phone more heavily to see how well the Air's charge holds up. With my normal moderate use, it will definitely last more than a day before I start using the iPhone's internal battery. It does take longer to charge both batteries together. If you have the chargers for the Air and iPhone with you, it's much faster to remove the phone from the case and charge them separately.
I do have a few very minor gripes with the Air. The bottom half's right edge does not line up perfectly with the top half's edge. The bottom one sticks out ever so slightly. It's just annoying since you feel the sharp edge while holding the phone at certain angles. Also, although the finish is shiny and beautiful, it makes handling the phone very tricky. I'm so afraid that the phone could easily slip out of my hands at anytime. With the extra weight and the slippery finish, I had to relearn how to hold the phone securely while typing in the vertical position. It would have been much better if the Air's finish came in either matte or rubbery or even leather. But these tiny gripes won't stop my from giving it 5 stars since I bought it more for the extra battery capacity. The full case and it's handsome look are all extras. …More290 of 317 people found this useful

More of a battery than protective case
Written by LR from Bloomington
Apr 29, 2009
For those frustrated by poor battery life of an iPhone I would recommend at least trying this. It does add mass and bulk to your iPhone. It nearly doubles the thickness, but remains comfortable in the hand. The two pieces of this unit fit nicely together. My 16GB iPhone is 4.7 ounces before adding the case, 7.1 ounces after. This definitely makes it heavier in your shirt pocket. I think if the case were silicon, instead of hard plastic, they would have something very protective. There's a toggle on the bottom of the case that allows you to use the battery or have it in 'standby'. The recess near the toggle for silent mode is a bit tight (awkward to do) when toggling back to 'ringer' mode. Despite this: Well made, well fitted and is useful in extending the run time of your iPhone.

useful but needs improvement
Written by JB from Ormond Beach
Dec 1, 2009
the juice pack should have pass thru capabilities for the standard iphone/ipod cable. It also could be more shock resistant I fear for the day I drop my iphone.
If i want to charge my phone while in the car I have to take the case off and put it back on when i leave the car. This was a big issue recenlty since i left my juice box in a rental which i had to track down to get back... nevertheless its great to have but needs improvements
so i give it 3 stars cause the extra juice is great... but its not a case for protection. …More2 of 2 people found this useful

Great idea - IF it worked as advertised
Written by MB from San Antonio
Nov 30, 2009
Now I know why the reviews on this product are so all over the place. I wanted one for plane trips. It's a great idea to have an auxiliary battery and protective cover all in one, but quality control must be very bad, as I have experienced almost all of the various warnings posted in other reviews.
Pro: It looks good, fits well, matches the iPhone design, and does not significantly increase the size of the iPhone versus other covers, IMO. My 3GS did not give me any warning messages when I attached it, so that problem must be fixed.
Con: It is very slow to recharge, gets hot, does not provide anywhere near the 50% or more battery life that some claim, and it clearly reduces the received signal strength on the iPhone. I had never even seen the Edge network icon on my iPhone until I installed this cover.
My experience: I brought it home, installed it and charged it fully, along with the main iPhone battery at 100%. (BTW, the battery strength lights are neat and kind of remind me of the charge lights on iBook batteries.) Anyhow, I turned the Juice Pack Air on and put the phone down and went on to something else. In about 6 hours the Juice pack was drained, with the iPhone totally idle and wireless turned off! My built-in iPhone battery will last several days in idle mode and limited use. I recharged the Juice Pack over several hours and turned it off. When my iPhone got down to 2% today, I then turned the Juice Pack on. It very quickly brought the iPhone battery up, but only to 36% and it got so hot while it was charging the iPhone battery that it actually burned my hand! It drained the Juice Pack totally and quickly. I have now had it plugged in for about 5 hours and it has just finished charging and has started to charge the built-in battery now, but has only gotten to 41% and appears to take *much* longer to charge the main battery through the Juice Pack than it does to charge the iPhone battery directly by itself with the Juice Pack off of the iPhone.
Perhaps I have been spoiled because my built-in battery charges quickly and lasts very well compared to other reports on battery life. This fully charged Juice Pack barely brought the built-in battery up by 1/3 before the Juice Pack was dead. That's not 50-100% increase in battery life! At $80, this is just not worth it for the required long charging time, loss of signal, and the generated heat. Perhaps I just got a bad one. In any event, this one needs to go back for exchange or refund. I note that the Mophie site offers re-furbished units.
Apple offers many great peripherals for the iPhone. This is just not one of them, in my experience. I need to look at inCase or one of the others mentioned in other reviews. Sad, I was really hoping for better results. …More2 of 3 people found this useful

My 2 Cents: Demo For Yourself
Written by AH from Spring Valley
Nov 30, 2009
I was leery after reading some of the reviews but took the plunge anyway. I bought it when I upgraded to the iPhone 3G(S) from the original iPhone. (It finally reached it's lifespan. lol)
Yes it is built on a lightweight case so even though it is also a case, connecting and disconnecting the cable must be done so with care. The plug company logo faces up when connecting. (I'm usually very gentle with my gear...)
I noticed that when I initially charged it to a full charge with iPhone connected, there was no apparent benefit. But I hung in there and gave it the benefit of the doubt and ran both units to battery depletion.
I gave it a full recharge and low and behold, the battery icon on the iPhone changed to a plug in the center of the battery. Since then I have been able to gain all the extra battery life as advertised.
It appears that the phone and the case battery needed to sync up somehow and it's all good now... Looks like another hit product for the power-user... I love it! …More4 of 4 people found this useful

I have the morphie juice pack, the Kensington batteries (both small and large types) and the Macally battery pack. This comes out tops for convenience (it fits as a csae as well as battery booster), style and sheer elegance. I have just ordered a second one today. CAUTION. I accidentally dropped my iPhone in its Juice Pack case and the top cover of the case has cracked - the battery still charges the iPhone but the crack catches my ear. Morphie should do replacement top covers to combat this scenario. …More
