In just a few hours from now, HTC will be unveiling the all new HTC One at its event in New York. However, that has not stopped the handset from being leaked once again, in a video where it is compared to its predecessor — the M7. 

The leaked video, posted by the folks over at TechSmartt, does a good job of comparing the new One to its predecessor. While the new One still comes with an aluminium unibody, it has a much more polished feel to it with the rounded edges making the handset more ergonomic.

The video also reveals the full specs of the handset, which has already leaked numerous times in the last few days: a Snapdragon 801 processor, 2GB of RAM, Sense 6.0, Android 4.4.2 KitKat, Dual cameras on the rear and a 5MP front-facing shooter. The video also gives us a demo of the dual cameras on back of the new One in action, which allows the user to refocus into any part of the picture.

According to the reviewer in the video, the new One is a great step up from its predecessor with the camera and battery life being significantly better. He also compares both handsets side-by-side, which shows how tall the new One is compared to the M7, along with running some benchmarks on them.

At this point, the only piece of information not know about the new One is when the handset goes on sale and at what price, which HTC should reveal at its event tomorrow.
