Most 5G phones offer big batteries owing to the increased power consumption of early 5G modems and connectivity. But just how much more power does a 5G phone need over a 4G device? From a report: Redmi general manager Lu Weibing has taken to Weibo to answer this question, claiming that 5G phones consume ~20% more power than a 4G phone. This suggests that a 20% increase in battery size is needed for a 5G phone to achieve the same endurance as a 4G variant (assuming everything else is equal). The Redmi executive adds that Qualcomm’s flagship 800-series processors consume 20% more juice than an upper mid-range Snapdragon 700-series chipset. So when taken together, this means a 5G flagship will consume significantly more power compared to a mid-range 4G phone, which means battery capacity and optimizations are key for high-end 5G phones.
