iPhone Mophie battery pack

I had a first generation iPhone and one of the limitations I found with it was the battery. Since you could not replace it and could not carry a spare you always had to be concerned with ensuring the battery was always charged. This lead to constantly plugging in. Now there are a number of products out there to solve this problem. Some clip onto the bottom and recharge the phone in an emergency. I looked at one of these and actually bought one from deal extreme but they are fragile and I am concerned with breaking the connector on the iPhone. My friend Jason found a Mophie Air. This is a clever design and it is the same size as the iPhone and it basically doubles the thickness of the iPhone. It doubles as a hard case and adds a 1200 MaH battery. This more than doubles the battery life of the iPhone! The unit has a switch on the bottom of it allowing you to control when the second battery is in use and not. They also included an indicator so you can tell the charge level of the external battery. The device is certified by Apple and is sold in the apple store. A great accessory for the hard core iPhone user. One word of caution though if your iPhone gets below 2% it will not power back on until it is back above 5% so switch the mophie on before you get too low or you will be without a phone waiting for it to charge. And we all know that will be the time your significant other really needed to get a hold of you 🙂 One other thing is the iPhone will think it is on ac when on the mophie so power management is not as aggressive as it would be normally, meaning it is slower to dim the screen etc.

The Mophie does efffect signal strength. If you are in an area of marginal cell signal you will notice the difference. In a city area where there is a strong signal the difference will not be noticeable. GPS reception is also effected by the Mophie sometimes making it impossible to get a lock with the Mophie on.

One of the issues with the mohpe that I have is that the mophie obstructs the button to mute the switch.

As you can see the small section near the volume control has broken. Yes I bite my nails 🙂

  1. Was the scratch on the back of your iphone a result of a defect on the Mophie design or it was just you being a bit careless?

    • I suspect some dirt got in between the iPhone and the mophie. I have not been able to find anything wrong with the mophie to explain it. It’s likely just due to the tight distances between the iPhone and the mophie.
