Redmi says it will launch a phone with a nearly 7500mAh battery soon in the form of the Redmi Turbo 5. Honestly, the development in the battery technology space has been staggering in the last few years. It was impossible to see such large capacities in a mainstream smartphone just a few years ago. Other brands such as Vivo and Oppo are also pushing to a 7000mAh. I think I would take a thicker phone everyday if it meant I did not have to charge it again and again.
