I want this battery case. It has plenty of juice and best of all, it looks like something that Batman would use. Again, it's all about the battery life or lack there of in the iPhone 4 and iPhone 4S has me considering getting this.
This Mophie Juice Pack Pro for $129 packs a punch that is unlike most other more anemic battery cases. I've help off getting them because they just didn't give me what I wanted given how I think mobile devices, particularly the iPhone, ought to be used.
For some comparison to the awesomely long battery life that the RAZR MAXX from Motorola has, the iPhone 4/4S really doesn't measure up. The RAZR has 3,300 mAh battery while the iPhone 4 has 1420 mAh and the 4S has 1432 mAh. A huge diff.
With this juice pack, the iPhone will have its battery life augmented by the pack's 2500 Ahm. That'll give the iPhone roughly 3900 Ahm.
Right now, we ration power when we know we're going to be away from the power plug for any length of time. I had an older battery case that I used with the iPhone 4 over July 4th and with some regular use and videos and photo captures, I ran out of power just half way through the firework display in Long Beach.
It didn't matter since we got back to the car 15 minutes later and I had a car charger that was able to get me back up and running in no time. Still, had the time gone on longer, I would have been out of luck.
This Mophie pack is the answer. So, why not get it? It's not the $129 because you are getting quite a bit of juice for this. rather, it's that the next iPhone is 3 months away. I can probably get quite a bit of mileage out of this for the next three months but I really hate to spend this kind of money and know be able to use the case with the iPhone that is likely to have a radically different form factor.
I hope that Apple is able to significantly increase the battery life for the next iPhone but I am not all that hopeful. With speculations about the 2012 iPhone sporting a bigger 4" screen and, quite possibly, thinner, any extra battery capacity Apple adds will go towards powering the bigger screen, a better CPU, and new iOS 6 features. It's unlikely Apple will be able to match what Motorola gave to the Max.
Apple will attempt to squeeze as much juice out of this bigger battery to at the very least maintain parity with the iPhone 4S usage.
Maybe, just maybe, I should hold off until Apple unveils the next iPhone and Mophie come out with a Juice Pack Pro for the new iPhone.
