HTC has allowed another smartphone to slip through its net and make its way into the wild prior to its official unveiling. This week its a device codenamed the Endeavor C2, and it's believed to be a successor to the One X — HTC's existing flagship smartphone.

According to a "trusty mole" for Stuff, the One X II will pack a 1.7GHz quad-core processor, a better battery, and a new paint job — though it's currently unclear what the new color will be. The handset will also be bundled with a set of UrBeats earphones, and it will be compatible with all existing One X accessories.

Although it isn't specifically stated in the report, that suggests the One X II will maintain the same form factor as its predecessor, with all changes being made internally.

As far as software goes, the One X II is expected to feature ClearVoice technology to improve call quality, and will also be the first device to run HTC Watch 2, the latest version of the Taiwanese company's on-demand video service.

Finally, Stuff also offers up some pricing details, and even a release date. The One X II is expected to cost £5 (approx. $7.82) a month more than the One X in the U.K., and could arrive on or before October 1.

If you've been looking to pick up the One X, then, it goes without saying that you may want to hold onto your cash for a little while. Although we can't be certain this information is entirely accurate, you wouldn't want to purchase a new smartphone just to see it replaced by a new model a couple weeks later.
