It's clearly a Chinese smartphone-maker battle on the Indian turf. Just a few days after Xiaomi announced a Rs 4,000 price drop on the Mi 4 64GB model to Rs 19,999, its Chinese counterpart OnePlus has also announced a price drop to Rs 19,998. But this offer will only be valid for June 18.

OnePlus One comes at Rs 21,999 for the 64GB variant and Rs 18,999 for the 16GB variant. On June 18, the 64GB model will get a Rs 2,000 price cut. So the Xiaomi Mi 4 and OnePlus One 64GB variants will compete at the same price point. The 16GB model will still be selling for Rs 18,999 though.
The OnePlus One smartphone has a 5.5-inch display at 1080×1920 pixel resolution, Gorilla Glass 3 protection, Snapdragon 801 processor, 3GB RAM, Android 4.4 KitKat along with 13MP rear camera and 5MP front facing camera. It is powered by a 3100mAh Lithium-ion battery. You can read the full review of the OnePlus One here.
On the OS front, you can either run the OnePlus' own OxygenOS or the Cyanogen OS 12, now that OnePlus has settled its issue regarding the use of Cyanogen OS on its phone.
