Is your iPhone battery to weak for your intensive usage? We know how frustrating that is. But fortunately the iPhone success leaded to a big accessory market. The mophie Juice Pack Air Case and Rechargeable Battery for IPhone 3G, is the best solution to recharge your iPhone battery on the go without using a charger. The case should improve the iPhone 3G battery life up to 50%. The mophie Juice Pack Air case is easy grip; it offers a full protection of a hard shell case and a built in rechargeable battery. This case is too form-fitting; it is easier to slide the iPhone in than to take it out; with the case on the phone the best way to take if off is to push it out, one side at a time. Push on the side of the case where the volume keys are and slide it slowly.



Repeat the process to the other side and the top of the case will slide off. You can now pull the phone out of the case. However the form fitting is not necessary a bad feature, because it will keep your iPhone secure and will protect it in case you drop your phone. Also the case is ultra thin and weights little in order to compete with the useless but high fashioned metal cases. The low profile case design hides a rechargeable 1200 mAh lithium polymer battery (with standby values up to 270 hours). Theoretically the case allows USB charging and sync with iTunes. In the real life field the cable offered with this case is more bad than good. The phone covered with the mophie Juice Pack Air doesn't succeed charging itself.

The same happens when you try to listen through the USB port of either stereo speakers or car stereo; while the syncing with iTunes is not as smooth or easy to happen. Your iPhone will just appear and disappear from the iTunes connected decide. However these are singular issues and are not general spread to all models of mophie Juice Pack. When you use continuously your iPhone, the battery will reach pretty fast 20% of its full capacity. The usage time to 20% is about 4 hours and 12 minutes and standby time has a value of 14 hours and 13 minutes. Then if you turn on the mophie Juice Pack and let it charge your iPhone battery for about 1.5 hours. After a heavier use, when the internal battery drops down to 20%, the full usage time of the iPhone reached 8 hours and 36 minutes and standby time of 19 hours and 54 minutes.

At the third charging with the mophie Juice Pack Air the iPhone's battery reached 9 hours and 24 minutes as usage time and a standby time of 22 hours and 17 minutes. After the third charge, the mophie Juice Pack Air runs out of power. Therefore the mophie Juice Pack Air case and rechargeable battery offers twice the battery power for the iPhone 3G.

The case is an easy grip touch case. When charging the iPhone 3G with the case on, both the iPhone and the mophie Juice Pack Air charge their built in batteries at the same time. The case offers USB charging and sync with iTunes for the iPhone.  The case dimensions are, as featured in the commercial ads, very form fitting, offering a light weighted and slim form case for the iPhone 3G. It has a height of 12.4 cm, wide of 6.6 cm and deep of 1.9 cm; while the released values of talk time reaches up to 4.5 hours on 3G network and up to 9 hours on 2G.

You can use the Internet up to 4.5 hours on 3G and up to 5.4 hours on Wi-Fi. The audio playback is up to 20 hours, while the video playback is up to 6 hours. Other special features offered by the mophie Juice Pack Air are: on and off switch for you to choose what battery to use (the phone battery or the case battery) and integrated 4 LED charge status indicator. But this case is not all that great, it still has some drawbacks. The case requires a special plug, used on digital cameras (but smaller), to charge the battery. It is not recommended for your mophie case well being to take it off every time you need to charge it. Also the case does not contain a dock connecter offered on the iPhone. Therefore, with the case on, your iPhone will not connect with any of the accessories with the regular charging port to function. Also this case will provide more power but not as much as you might think.

If your battery is lowered to about 20% you can expect the 1200 mAh built in rechargeable battery from the mophie case to give your iPhone 3G another 50% battery life. However if the phone battery drops under 5% the case will not charge your iPhone rapidly enough, therefore your phone will run out of power. The finish on the case makes it a bit slippery and also is not shockproof. Beside the actual case, mophie delivers in the box an USB cable for charging and syncing and that is it.

Overall, the design of the mophie Juice Pack Air is solid. It's slimmer than other battery pack cases, because of the materials used it feels nice at touch, status lights on the back are a great feature, micro USB port allows you to sync to your computer. As a technical feature, the iPhone internal battery has to offer in terms of usability, 4 hours and 12 minutes, while the iPhone with the case offers in the same terms up to 9 hours and 24 minutes. This case is a compromise. It offers extra battery life for you to use your iPhone for business or pleasure. It's a compromise because fashion is over function (you might be losing signal strength - about two line on average).
