Check how many Milliamps the battery of the Mophie Juice Pack Air has. An iPhone 4S battery has 1432 Milliamps and if an external battery/battery case is supposed to provide a full charge it has to have at least that much and, in my experience, a bit more capacity than that. I have a MyCharge Peak 6,000 which has 6,000 Milliamps. This means it should charge the iPhone about 4 times since 1432 Milliamps times 4 is 5,728. However, in my experience I get about 3 charges out of it if I recharge when the battery on the iPhone is between 20 and 30%. If I let it run down almost completely to maybe only 2 or 3%, I probably get 2 and a bit from the Peak 6,000. It would be my guess that a battery would have to have at least 1,600 or 1,800 for it to comfortably charge an iPhone fully. If it has only 1,000 or 1,200 MA it will probably charge the iPhone back to 70 or 80% if you start the recharge at the 20% warning.

It is supposed to almost double your iPhone talk time between charges. I am looking to get this so that I may last a whole day with my 4S. Any comments? Web reviews are very contradictory. Some swear by it and some call it trash. Will appreciate actual user remarks. Thanks in anticipation! -- You received this message because you are subscribed to the "VIPhone" Google Group.
