Here’s why:

  • Battery Life: The primary reason is the significantly larger 5160mAh battery. For my daily usage, which includes a lot of browsing, media consumption, and some gaming, a long-lasting battery is crucial, and the Xiaomi Poco X3 Pro delivers.
  • Versatility The Xiaomi Poco X3 Pro has a versatile camera and has a lot of sensors for various functions.
  • Performance on a budget: While the realme 8's chipset is newer, the Snapdragon 860 is still very capable, and the 8GB of RAM provides a very good balance between performance and price.
