One persistent problem that we’ve kind of gotten used to is the battery issue with smartphones. In the case of iPhones, the problem is quite grave. A typical usage doesn’t get me through a single day without recharging the iPhone. The iPhone 5, with all the larger display and features, does come with a larger battery but not enough to compensate for the usage.

That is perhaps why battery cases and juice packs are enormously popular. We decided to take a look at what’s on offer for iPhone 5 users in the world of battery cases. These are not juice packs like the ones provided by Mophie. The battery cases serve as a case but that’s not their main function: they add life to your iPhone 5.

Take a Look at 5 Ultimate Battery Cases for iPhone 5:

1. uNu Aero

uNu Aero iPhone 5-5s Battery Case

Capacity: 2000mAh
Price: $99.95 ($79.95 on Amazon while writing this)

  • LED Power Indicator
  • Standby Switch
  • Ultra thin
  • USB port available

The uNu Aero focuses on being the perfect eco-friendly case and battery for your iPhone 5. A neat design and an equally neat battery pack that offers more than twice as much talk-time, video, 3G and music than the iPhone 5 does is the forte. If you’re looking at a powerful battery case, that also features an extra USB port for power-sharing, this is it.
