Now that the brouhaha over the iPhone 3G has calmed down, users have now to deal with the problem of low battery life so typical of a device packed with Apps and with 3G connectivity. We have earlier dealt with ways and means of increasing the battery life of the iPhone 3G. For those of you for whom the tips to expand the iPhone 3G battery life appears unexciting, they are left with no other option other than recharging the battery as frequently as possible. To make the recharging process easier you could try the Solar Powered cases for the iPhone 3G. The inbuilt 1500mAh case battery can provide one full charge to the iPhone, the case battery in turn being recharged through the solar panel mounted on the front of the case or in case of non-availability of sunlight via mini USB. Besides protecting the iPhone from scratches and dust, imagine the utility of the Solar Powered case in not only charging the iPhone battery but also using clean energy for the process.
