There were rumors last week that HTC is going to launch a new device, called HTC One X10, following leaks courtesy of social media posts. Now, it seems that the device is already officially available, but only in Russia.

On Thursday, popular leakster Evan Blass posted on his Twitter account about an upcoming phone from the Taiwanese company. The image does not indicate its name, but teases that it will be a device where "big style meets bigger battery." Many speculated that it is the HTC One X10.

Just a few days after the leak, the device seems to have become officially available. However, it was only sold in Russia. The HTC One X10 comes with a 5.5-inch display screen with 1080x1920 pixel resolution. Its appearance resembles HTC's One M series but also infuses a new look through its metal body.

Under the hood, the HTC One X10 is powered by a MediaTek Helio P10 processor. Along with this, it comes with 3 GB of random access memory (RAM) and 32 GB of internal storage that can be expanded through a microSD. The HTC One X10 also runs in HTC's Sense software, coupled with the Boost+ feature that is expected to help speed up the performance of the device.

As for its camera, HTC One X10 comes with a 16-megapixel main shooter with f/2.0 aperture, along with an 8.8-megapixel front snapper. The device also comes with a fingerprint scanner and supports dual sim and 4G long-term evolution (LTE).

Meanwhile, the HTC One X10's biggest feature is its battery at 4,000 milliampere-hour (mAh). This is expected to make the new device last longer of up to two days.

The specifications of the HTC One X10 are consistent with the speculations initially revealed by HTC Source.

At the moment, the HTC One X10 costs 19,990 rubles or about $355. There is no announcement yet if the HTC One X10 is going to be sold in other regions. More details will likely be revealed soon.
