Original (February 6th, 2020)
Redmi has announced a new smartphone launch event for February 11th in India. It has set up a dedicated page on the official website to tease some of the key features. A similar page is available on Amazon India as well confirming that it will be the exclusive partner for online sales of the upcoming phone.
The dedicated page is teasing three salient features as Dumdaar Camera, Dumdaar Battery, and Dumdaar Design where "Dumdaar" is a Hindi word for "powerful". It reveals that the upcoming smartphone will have dual rear cameras for better portrait shots, a huge 5,000mAh battery "to do more this 2020", and a textured back panel design for a "superior hand feel" and "superior grip".
Redmi is promoting the smartphone as "Desh Ka Dumdaar Smartphone" which translates to "Powerful smartphone of the country". It is the same tagline that was used for the Redmi 8A India launch late last year. This suggests that the upcoming smartphone will likely be the Redmi 9A, a direct successor of the previously unveiled phone.
Another reason to believe this speculation is that Realme has launched a new budget smartphone Realme C3 in India today. It would make perfect sense for Redmi to bring its own product to compete with one of its closest rivals. This makes the Redmi launch event even more interesting.
