While ASUS’s “ZenUI” is lightweight compared to Samsung’s One UI or Xiaomi’s MIUI, it still carries background services, battery-draining optimizations, and proprietary apps that cannot be removed without root access.

Users frequently report a noticeable increase in Screen-on-Time (SOT) after installation, as the operating system no longer runs ASUS’s battery management daemons or data-collection agents.
