When evaluating hardware, focus on the Processor (CPU), such as Snapdragon Wear or high-efficiency MTK chipsets, to ensure smooth UI performance. RAM and ROM capacity are critical; for full Android OS watches, a minimum of 2GB RAM and 16GB storage is recommended for app stability. Additionally, verify the Display Type, prioritizing AMOLED screens for better sunlight visibility and battery efficiency, and ensure the Battery Capacity is at least 400mAh to 800mAh to support 4G LTE and GPS functions.
