Power your life anytime, anywhere with the Mili Power Spring external battery pack for iPhone 4S / 4.
Super-thin design adds minimal bulk to your iPhone 4S / 4
External battery cases are essential for heavy users of modern smartphones, but often are bulky or unattractive. The Mili Power Spring for iPhone 4S / 4 is only 18mm thick when applied to the iPhone 4S / 4, meaning it adds less than 9mm to the thickness of the device. It is also stylishly designed in glossy, curved black plastic, so your iPhone 4S / 4 will still look as good as ever when using this battery pack.
1600mAh rechargeable battery pack doubles your iPhone 4S / 4's battery life
While the battery life of the iPhone 4S / 4 is a marked improvement on previous generations, you're lucky to get more than a day or two out of it with moderate use. With the Mili Power Spring, however, you don't have to worry about charging your phone every day. The 1600mAh Li-Pol battery provides up to 450 hours more standby time, which translates to up to 7.5 hours talk time on 3G, 16.7 hours on 2G, up to 7.5 hours internet use on 3G or 13.3 hours on WiFi, up to 45 hours of audio playback, or up to 15 hours of video playback.
Innovative folding mechanism for easy insertion and removal of phone
The Mili Power Spring features a patented folding mechanism which allows you to easily insert or remove your iPhone 4S / 4 from the case. This means it's less of a struggle to use the case, and less likely to damage your phone in the process.
Made for iPhone 4S / 4 with official Apple license
The Mili Power Spring is designed specifically for the iPhone 4S / 4, so you can be sure of a perfect fit with your device. It also has the official Apple "Works with iPhone" certification, which means it is guaranteed to be compatible with your iPhone 4S / 4. The battery pack also features cut-outs for the buttons and camera, so you can access the full functionality of the device without taking it out of the case. Please note that the Mili Power Sprind is charge via micro USB, not by the Apple dock connector.
