Reviews for Mophie Juice Pack Plus Battery Case for iPhone 4S/4

It looks great, feels fantastic and sounds like a great idea. But, here are some of the issues that I faced. A) the first juicepack plus that I bought turned out to have some problems with the standby switch and syncing with itunes (which i tried on the Macbook Air, A windows 7 laptop and a Windows 8 desktop just to be sure). B) In the exchanged piece, while the standby-power switch problem got resolved, the sync problem remained. Some folks online have complained about non-sync with itunes (some attributing it to ios 5 and above) which is one of the product's major pitches (canned air applied to the connector has been pitched as a possible solution but didn't work for me). So I would say if you want to buy the juicepack plus definitely a) test if the standby power mode is working correctly (try switching between them a few times to check, it should work seamlessly every time) and b) Check whether the USB sync works fine with your laptop (I actually bought my macbook air to the store where I bought it from to demonstrate the issue, but while they were courteous, they were stumped about this issue).
