The HTC One S (codenamed Ville) is one of HTC's premium smartphones which is part of the HTC One series. It has Beats Audio and runs on the Android 4.0 "Ice Cream Sandwich" mobile operating system with HTC Sense. 

Slotted between the low-end HTC One V and the high-end HTC One X in the HTC One lineup, the One S's specs and positioning are close to that of the flagship One X. The One S and One X share the same dual-core processor, though the One S lacks LTE. The One S has an aluminum body and a 4.3-inch 960x 540 pixel (qHD) Super AMOLED display with PenTile matrix with a pixel density of 256 pixels per inch, compared to the One X's polycarbonate body and a 4.7-inch (120 mm) 1,280x720 pixel (RGB matrix) Super LCD 2 display with a pixel density of 312 pixels per inch.

The One S's use of a PenTile display makes it more energy efficient and thinner than equivalent LCD screens, giving it better battery life than the One X. While their rear-facing cameras use identical 8-megapixel sensors, for the front-facing camera the One S has a VGA cam and video capture fixed at 640 x 480 resolution compared to the One X's 1.3-megapixel sensor with 720p HD video capture.
