Tired of finishing the day with next to no battery on your phone or worse, having it die mid e-mail/tweet/message? Nanocase might have the perfect solution for you with a new graphene iPhone case that will actually improve your battery life. The slim and sleek Nanocase uses graphene, the extremely efficient heat dissipating material used in space research, biotechnology and nanotechnology, to remove heat more effectively than any other material, which ultimately means your device will stay cooler under load thus potentially increasing the battery life while also extending the working life of the phone overall. It’s also worth mentioning that the “cooling” effect of the Nanocase means you won’t have to worry about hot hands or laps during extended periods of use. The only real caveat with the Nanocase is that, unfortunately, it’s only currently available in the UK. A US launch will be happening in the near future, but a specific time frame has not been confirmed.
