There is no escaping it; we all must keep charging and re-charging our iOS devices, some more often than others. And if you absolutely need your iOS device powered up in order to keep connected, then some of the following charging options might help you stay up and running. If you find that you just cannot make it through even one day on a full charge, then a self charging case is likely your best bet. For the iPhone 5 and 5S, Mophie has three different case chargers to choose from. The helium for $79, the air for $99 and the plus for $119. With the iPhone being so thin already, a charging case does not add all that much bulk. The difference between the three, besides their size, is how much battery capacity each has. The thinnest case has a 1500mAh battery and will charge your iPhone back up to 80 percent where the thickest has a 2100mAh battery that will charger 120%.
