Realme has dropped a teaser poster on platform X, revealing plans to showcase a groundbreaking new smartphone on August 27. This device will be equipped with a colossal 15000mAh battery, a capacity that vastly surpasses that of typical smartphones and rivals some portable power banks. However, this enhanced battery life comes with a trade-off: the phone's body thickness has increased proportionally. Notably, Realme's current 10,000mAh battery technology is still in the developmental stages within its labs and is not expected to hit the market in the near future.
