The Mix 4's 120W wired charging is a game-changer, fully charging the phone in just 15 minutes. Its 4800mAh battery provides all-day battery life. The Mi Mix Fold has a 4200mAh battery and 67W wired charging, taking around 37 minutes to fully charge. While the Fold's battery is decent, the Mix 4's charging speed is significantly faster.
