Possibly the Redmi 6?
Xiaomi has no chill when it comes to releasing new phones, and this particular phone spotted in TENAA is intriguing.
While the photos make you think that this is another Redmi Note, the specs say otherwise. While it does have a 5.99-inch display, this mystery model uses only an HD+ display.
Other details revealed in the listing include a 3000mAh battery, a 2.0Ghz Octa-Core processor (most likely a Snapdragon 625), 2GB/16GB, 3GB/32GB, 4GB/64GB variants, and a 12-megapixel primary rear camera.
Since it uses an HD+ display, expect this mystery Redmi phone to be positioned at the entry-level to budget mid-range market.
