Lenovo unveils K80, a phone with 4GB RAM and 4,000 mAh battery

Not long after Asus announced the ZenFone 2 as the world's first smartphone to offer 4 GB of RAM, and Xiaomi introduced the Mi Note Pro with 4 GB of RAM, now Lenovo unveiled its own handset with 4 GB of random-access memory.

Called Lenovo K80, the new handset will directly compete with the Asus ZenFone 2 not just because it offers 4 GB of RAM, but also because its price and other features are relatively similar to those of Asus' smartphone (which is already available in select markers, including China). 

The K80 runs Android Lollipop, sports a 5.5-inch 1080p display, and is powered by a 64-bit Intel Atom processor clocked at 1.8 GHz. The handset also offers LTE, a 13 MP rear camera with Optical Image Stabilization, 64 GB of storage space, and a very generous 4000 mAh battery. The K80 is 8.5mm-thin, and comes in various color variants, including black, silver, and red. 

The handset carries a price tag of 1,799 CNY ($290), and will be available in China starting April 30. A variant with 2GB RAM and 32GB internal memory will also be released. It isn't yet known if and when the K80 will be available in other markets.
