Last year we saw the announcement of two smartphones with absolutely huge batteries, the Oukitel K6000 and K10000. Neowin was able to get their hands on the devices and wrote up a review for both of them. They felt the K10000 was simply too big for a smartphone and the camera quality wasn't great either. They did like the design, performance, battery life and the ruggedness though. On the other hand, they felt the K6000's build quality wasn't that great and again, the camera wasn't very good either. But they still enjoyed the smooth OS and its performance, the price and again, the battery life.
