If you were curious to find out just how big the new LG G3 is which we will see unveiled in a few days, then the above picture is your ticket. This leaked pic is a press render of the phone inside a slim-style case. With the case on, it's dimensions shown are 150 x 78 x 13 mm. Compare this to the actual dimensions of the LG G2 without a case, which is 138.5 x 70.9 x 8.9 mm, and we start to get a relative picture.
It obviously makes sense that the phone will be a bit larger, since it is coming with a 5.5-inch display. Still, if we do some mental extrapolation, it seems like LG will have done a remarkable job in not adding to much size to the overall case design compared to the G3's predecessor. What size do you think the final result will end up being if we subtract out the average slim case?
