The HTC One (2014) will measure 146.36 x 70.6 x 9.35, making it a little thicker than its main rivals. Weight is set at 160g. The screen will indeed be a 5" 1080p unit. The processor is quoted to be a quad-core 2.3 GHz Snapdragon 801, while the battery capacity will be 2,600 mAh. The SIM is said to be of the nano variety (like on the iPhone 5, 5c and 5s, Moto X, etc.) and there will be a microSD card slot to compliment the preloaded 16 GB of storage (10GB of which will b e user available).
Not so good battery, and not so good screen real estate because of the extra HTC logo bar on the front. The camera(s) looks interesting though. Dual cameras for making better auto focusing.
