Previous leaks involving the HTC One (M9) only gave the tech community glimpses on what the much-awaited flagship smartphone will pack. But the newest leak courtesy of China-based website Upleaks has ultimately taken the covers off the smartphone, revealing all its specs ahead of its unveiling predicted to take place on March 1. 

According to the leak, the HTC One (M9) will come with a 5-inch IPS display that renders a 1080p resolution. It will be powered up by the newest 64-bit Qualcomm Snapdragon 810 processor, which has four cores set at 1.5 GHz and four more clocked at 2 GHz as well as an Adreno 430 GPU. This will be paired up with 3 GB of RAM along with either 32 GB or 64 GB storage. There is a microSD slot in the device, too. The HTC One (M9) will run Android 5.0.2 Lollipop tied up with HTC's very own Sense 7.0. 

Furthermore, the upcoming handset will house a hefty 20.7-megapixel rear-facing camera with dual LED flash along with a 4-megapixel UltraPixel front-facing camera, which is likely the same one used on the HTC One (M8). The forthcoming HTC offering will also have a 2840 mAh battery, which is bigger than its predecessor by 240 mAh. GSM Arena added that the HTC One (M9) may sport handsome BoomSound speakers. 

Upleaks also revealed that the device will come to the United States with carriers AT&T, Verizon, Sprint and T-Mobile putting it forward. It will also be released in Canada (ROGERS, TELUS), Latin America, Asia, Europe, Africa, UAE, Russia, Turkey and Mainland China.
