housing MiLi Power Spring Battery Case is according to its manufacturers the thinnest case with an external battery for iPhone. You all know that external iPhone batteries always come with a rather thick case that almost doubles the shape of the terminal, but the MiLi case is different. First of all, it is only compatible with iPhone 4, so it benefits from the fact that the terminal is much thinner and thus the construction of the case allows the battery to be mounted in a small space and once mounted on the phone it should only add a few millimeters to its thickness. The case not only charges the phone but also protects it from scratches/shocks, and its capacity can double the autonomy of the battery considering that the manufacturers have included a 1600 Mah battery in the case.
Here is what the case offers:
- Utra Thin, just 18mm (or around 3/4 inches) thin, say goodbye to your bulky battery for iPhone
- Double your battery life – 1600 mAh stored inside.
- Protection to your iPhone from knocks and scratches with its hard shell case.
- "Made for iPhone" Approved.
Here are the specifications of the case:
- Product Computability: iPhone 4G
- Capacity: 1600mAh (Li Pol)
- Standby Time: Up to 360 hours
- Talk Time: Up to 6 hours on 4G
- Internet Use: Up to 6 hours on 3G
- Audio Play: Up to 36 hours
- Video Play: Up to 10.6 hours
- Dimensions: L124 X W65 X D18MM
I have always preferred to stay with the autonomy of the phone's battery than to buy such a case, and this one from MiLi has not changed my preferences in any way.
The MiLi Power Spring Battery Case costs $150, a rather high price (I say) for what it offers.
