Sony's Xperia Z3 Compact is expected to be a mini version of the Z3 flagship, and the phone recently passed through the FCC in two separate variants for different carriers: FCC ID PY7PM-0810 and PY7PM-0812.
According to the FCC documents, the device will have a 4.57-inch screen, and overall dimensions of 127 x 64.9 mm. That comes out to be the third highest screen to phone size ratio of any Sony Xperia device — 69.85 percent. The original Xperia Z was 69.83 percent, the ZL was 74.97 percent and the T2 Ultra was 71.69 percent.

The internals of the device are expected to include a Snapdragon 801 processor, 3GB RAM, 16GB storage, as well as a 20.7MP camera. The release of the Z3 compact is expected to come at IFA on September 3.

Now this sounds very good for the smaller Screen field many users still want but with super duper high-end specs. Anything bigger than 5.2 inches is way too big for my taste
