Mobile World Congress kicks off today, which means a bevy of mobile announcements this week. It starts with Lenovo, the world's top PC company, announcing three new smartphones as part of its S series. They include the S860, S850, and S660, all three of which come equipped with a quad-core processor and longer battery life than Lenovo's previous generation models, the company says.
Starting from the bottom, the S660 (PDF) is a compact device with a 4.7-inch IPS qHD display (960x540) powered by a MediaTek 6582m 1.3GHz quad-core processor and 1GB of RAM. It also has 8GB of internal storage (expandable via microSD card slot), 802.11n Wi-Fi, Bluetooth 4.0, 8MP rear-facing camera, 0.3mp-front facing camera, removable 3,000mAh battery, and Android 4.2 Jelly Bean.
Sitting in the middle is the S850 (PDF) with a 5-inch HD display (1280x720). It has the same processor and RAM as the S660, but twice as much internal storage (16GB), 13MP rear-facing camera, 5MP front facing camera, and a non-removable 2,000mAh battery.
At the top of the totem pole is the S860 (PDF) with a 5.3-inch HD display. The same quad-core chip is found in the S860, but it has more RAM (2GB), 16GB of internal storage, 8MP front-facing camera, 1.5MP rear-facing camera, and a non-removable 4,000mAh battery.
Lenovo said the S660 ($229), S850 ($269), and S860 ($349) will be available in select markets starting in June 2014.
