Due to the higher number of transistors and greater density, data processing efficiency is faster and power loss is lower, while the CPU's main frequency, as well as overall arithmetic performance and efficiency, are greater. This offers the advantage of faster application launches on the smartphone and improved performance. A longer battery life compared to the Realme 8i is particularly interesting for users who frequently use their smartphones. Displays with a high refresh rate eliminate animation blur and provide a significantly better user experience when scrolling and gaming. The Realme 9i is equipped with the first Snapdragon 680 6 nm processor in this segment. As an optimal powerful Qualcomm 4G processor, it ensures extensive performance improvements for the smartphone. A charging technology with higher voltage and lower current is integrated for faster charging. Through stepless variable speed adjustment, voltage and current can be intelligently adjusted. The unit is finely tuned with a drive of 500 mA, improving charging efficiency and reducing unnecessary heat loss generated during charging.
