Macoox wants to bring back the days, where batteries weren't finished after a single day (although it is probably the internet's fault). Their newest handset will be published with a 9,000 mAh battery inside. 

The device, called EX1 has a 4.5-inch display, 1GB of RAM, 8GB of onboard storage and is powered by an undisclosed quad-core processor.

Unfortunately, it seems that the phone will be quite thick - 15 mm may not appeal to everyone. At least when are lost, the device will come in handy - the GPS will navigate you out of trouble.
