MiLi Power Skin iPhone Battery Case – Review


The MiLi Power Skin Battery Case, is a new battery charger case that works with the iPhone 3G and iPhone 3GS, and according to the manufacturers it is the ‘worlds thinnest iPhone case with battery charger’.

The case is pretty thin, measuring just 18mm at its thickest point, and it is definitely the thinnest we have tested so far. When you place your iPhone in the case you notice just how thin it is compared to other models available.

The case is comes in two parts which clip together to protect your iPhone,as you can see in the photo below, it is very easy to use, just slide your iPhone into the case and then put the top part of the case on.

The case is made from a hard shell plastic, and it features a sleek black paint finish, similar to the back of the iPhone, it is a bit prone to finger marks, but not any more than the iPhone 3G or 3GS.

On the bottom of the case there is a microUSB port that is used to charge the case via USB, and on the side there is a button that lets you check the battery power, plus a battery indicator with built in LEDs which shows you how much charge is left.

According to the manufacturer, the MiLi Power Skin will give you up to 19 hours of audio playback, and up to 5.4 hours of video playback, with a total of 230 hours of stand by time.

On top of that there is up to 3.9 hours of Internet usage on 3G, and up to 3.9 hours of talk time on 3G, via the built in 1200mAh (Li Pol) battery.

We have had a good chance to test out the MiLi Power Skin over the last couple of days, and have been very impressed with it.

We got just over 5 hours of video playback out of it and a massive 18 hours of audio playback, which is very impressive, browsing via 3G came it an just over 3.5 hours.

The MiLi Power Skin was tested using an iPhone 3GS, and overall the results are impressive. This is definitely one of the best battery backup devices we have tested for the iPhone so far.

I like the design, it fits neatly over you iPhone and doesn’t add as much bulk to it as some of the other cases we have tested, yet it still gives you a decent battery life.

If you are looking for a new battery backup for your iPhone 3G or 3GS, I would definitely recommend looking at the MiLi Power Skin.

If you want one, the MiLi Power Skin is available in a variety of different colors, for £49.99 about $80 from Power Skin.

    The Mili Powerskin does NOT have a on/off switch as you mention. The only switch is the push button to check the battery charge i.e. lights the LED’s.

    Hi Clive

    Thanks for pointing that out.

    Just bought one of these. How can I say this politely! Not impressed. When the case is connected to the iPhone and you hook it up to your computer, two things happen.
    1. The iPhone charge indicator never comes on.
    2. The iPhone warning triangle comes on and states that the Juice Pack is an unsupported device and will not sync or charge!

    So Monday morning this pile of rubbish is going back.

    I basically have to split the case and charge them separately, very very poor. My rating 1/10.

    That is a great looking battery case, much more stylish that the “others.”
