The Juice Pack Plus – Squeezing every last millimetre of ‘juice’ out of an iPhone 4

The slightly nauseating Americanism, of referring to putting petrol in a car as ‘juice’, has now moved into mobile phone technology, thanks to Mophie, the California-based designer and manufacturer of mobile intelligent devices and accessories. Aiming to provide iPhones with an extra boost of power and protection, Mophie launched a ‘juice pack’, which actually won awards for its originality and design. Taking the juice pack line even further, Mophie have now announced the ‘Juice Pack Plus’ for iPhone 4, a battery case designed to improve the aptitude and capabilities of the iPhone 4.


This ultra-light and stylish battery case will only put an extra 1mm of thickness to an iPhone, and, by including a dual injected rubber grip, provides users will extra grip to clutch their beloved iPhone extra tightly. The Juice Pack Plus more than doubles the battery life of an iPhone 4, meaning users will have an additional hours of talk time on 3G and 16 hours on 2G, up to 7 more hours of internet use on 3G and 11 additional hours WiFi, as well as whopping 11 extra hours of video playback.

Not only is the Juice Pack Plus the biggest juice pack case produced thus far, enabling devout iPhone users to squeeze every inch of potential battery life out of their fave gadget, but Mophie’s latest invention also acts as a virtual speaker box, which by redirecting sound from the bottom of the iPhone to the front, results in a richer, deeper and more fuller quality of sound.

Having become fond of their new sleek and stylish iPhone case, which, BTW is available in black, magenta, yellow and cyan, users will be likely to be reluctant to remove their iPhone capacity booster to charge or sync their device to iTunes. Fear not, as a pass-through USB cable included, enables users to simultaneously charge and sync their iPhone without having to remove it from the Juice Pack Plus.

Similar to a car’s fuel gauge, which tells you exactly how much “juice” is left in your vehicle, an integrated 4 light LED battery status indicator tells you how much “juice” is left inside the Juice Pack Plus.

If you think stretching your iPhone’s original battery life further, which, has incidentally been described as being “outstanding” and apparently exceeded Apple’s expectations for longevity during testing, it may prove provident to fork out £89.95 for a Mophie Juice Pack Plus.

iPhone case roundup

Sprucing up an iPhone whilst giving it extra protection is all the rage at the moment with a whole host of cases bombarding their way onto the market. LG looks at some of the best cases to give your iPhone that extra ‘wow’ factor.


Incipio Feather


As its name denotes, the ‘Feather’ is an ultra lightweight case available for the iPhone 4. By fusing functionality, style and practically no additional bulk, it is hardly surprising that the Feather is Incipio’s best-selling case.


Anything claiming to be ‘revolutionary’ can always afford to bump up the price and this is most certainly the case with the Incipio SILICRYLIC. Being an innovatory two-part case, a shock-absorbing silicone core wraps itself round the iPhone 4, whilst hard shell shields on the corners and the back, give the phone additional protection. The SILICRYLIC is available in a variety of vibrant colours.

Incipio NGP


This “Next Generation Polymer” – aka the NGP, provides a semi-rigid shell for the iPhone 4. Being dense yet flexible, the NGP resourcefully protects against knocks, whilst enduring resistance to any tears and stretches. The NGP is available in different colours, which seems to be an inherent characteristic of most iPhone cases.

Cygnett Snap Duos


These silicon frames provide 360 degree protection without compromising access to all controls and connectors. These modern cases are available in black, grey, blue, yellow, red, turquoise and orange, and even solves antenna issues associated with the iPhone 4.

Scosche metalliKASE


If shiny, shimmering and modern chrome takes your fancy, then this chrome finished metallic polycarbonate case may be just the caper to protect your iPhone 4G with adding virtually no bulk whatsoever. All switches and buttons are easily accessible, and if you really had nothing better to do, you could spend all day cleaning the mirrored screen protector with the microfiber cleaning cloth provided!

Scosche switchback


At a slightly higher price you would expect the Scosche switchback to offer a little more than other iPhone cases. And it does, actually, as it comes with an integrated kickstand, which is great for watching videos ‘hands free’. The Scosche Switchback is available in four interchangeable colour combinations and is made from a durable polycarbonate material, which guarantees complete protection of the iPhone 4.

Mophie Juice Pack Air


Dearer still, the Mophie Juice Pack Air doubles up as a protective case and a discreet battery charger, ensuring your iPhone 3GS has enough ‘juice’ in it at all times. Being the ‘world’s thinnest rechargeable battery case’ and being available in four stylish colours, the Juice Pack Air is quickly gaining the reputation of being a ‘must have’ accessory for the iPhone 3GS. A version for the iPhone 4 is also available and we’ll be taking a closer look at it tomorrow.
