For owners of the iPhone 6 and 6S, your battery worries may be over with Apple's very own Smart Battery Case.

The product stems from a recognised problem regarding iPhone battery life. Already available online, the battery case is selling for $99 and according to the brand, the product can extend battery life to between 18 and 25 hours depending on the functions used, from video playback and internet surfing to calls.

The battery case fits onto the phone like a regular iPhone case with an added surface thickness and a silicone exterior. Available in either charcoal or white, the case is charged via a standard Lightning port and can be charged simultaneously with the iPhone.
