You should get yourself a Samsung ATIV S. Its highly underrated and a great device. Better than the 920 IMO (in specs, not features)
Its battery is 2300mAh which could last me the whole day and left with 20%. (Did I mention it can support a Mugen Power 4800mAh extended battery?)
It has a 720p display Super AMOLED screen which have better viewing angles than the Lumia 920. IMO I prefer the Super AMOLED over Nokia's ClearBlack AMOLED or IPS LCD display.
It has the same 1.5GHz Snapdragon S4 CPU as all the high-end Lumias (Lumia 920, Lumia 925, Lumia 928)
Its incredibly slim at 8.7mm throughout the device.
It has a surprisingly great 8MP camera and an outstanding 1.2MP front-facing camera which its front-facing camera is MUCH better than the one on the Lumia 920.
It weighs a very-light 135g.
It features expandable storage via Micro SD up to 64GB (Total 80GB). A feature not found in high-end Windows Phones until the Lumia 1520 (Yeah, the Lumia 1520 and ATIV S are currently the only high-end devices with a micro SD slot)
Its a highly underrated and under-appreciated Windows Phone 8 device. Its great and I've used the HTC 8X, Lumia 920 and the ATIV S and by far, I loved my ATIV S.
Because of its under-appreciated nature, the device is REALLY cheap. You could get one from Expansys USA for $259.99!
