Redmi K90 tipped to launch as Android smartphone with even bigger battery

The Redmi K80 is part of the Android smartphone battery size revolution of 2024 with a rated capacity of 6,550mAh, which is also its main advantage over its Pro sibling. However, there are already hints that the next generation of the brand's main handset line might be even better - and bigger - in this regard.

The renowned leaker Digital Chat Station now asserts that Redmi has secured massive ~7,000mAh batteries for its next-gen smartphones, even sub-flagships like the K90. Then again, other brands such as OnePlus are reportedly about to make the same upgrades in 2025.

Furthermore, it is possible that a successor to Realme's relatively affordable GT6 might also outdo Redmi by sourcing its 2K+ LTPS ultrasonic fingerprint-reading display from Samsung rather than a Chinese supplier such as TCL CSOT or BOE.

In the meantime, the number of K80 and K80 Pro units already in use since their November 2024 launch in their native country has reportedly exceeded 1 million, thereby mirroring an achievement made by the flagship 15 series from Redmi parent Xiaomi.

That alleged sales performance might bode well for the K80 globally, as it is thought to debut as a successor to the Poco F6 Pro on sites such as Amazon in 2025.
