Size matters in the world of iPhone accessories and contrary to what you may have heard, smaller is better! Well at least that’s the case with this ultra slim battery case for iPhone 4 / 4S. This sleek case features a powerful 1500mAh battery that allows you to use your iPhone for close to double the normal time and doesn't tack on much additional weight/size, still giving you that perfect iPhone 4 / 4S feel.
Unlike 99% of the other iPhone 4 / 4S battery cases on the market, this one is so slim that you can easily put it in any jean or shirt pocket without noticing any difference at all. In fact, both the minimal thickness and weight of the case are hardly noticeable and will feel very natural in both your hand and pockets. After a few minutes you'll completely forget it's even there!
On the side of this case is a battery level indicator with blue LED lights for checking the battery’s charge status. When you need to recharge, just do so like you would normally and by using your own iPhone cable. Simple and convenient.
