Display Comparison
The Ulefone Watch Pro's display specifications are currently unavailable, but given its price point, it likely utilizes a standard LCD panel. The Xiaomi Watch S1 Active, based on Xiaomi's previous smartwatch offerings, may feature an AMOLED display, offering superior contrast and color accuracy. The absence of information regarding peak brightness for both devices makes a direct comparison difficult, but AMOLED generally excels in outdoor visibility. Bezels are also unknown for both, but a key differentiator could be the presence of features like Always-On Display (AOD) which is more common on AMOLED panels.
Camera Comparison
Neither device is advertised as having a camera, so this section is irrelevant. Smartwatches rarely prioritize camera functionality.
Performance
Without chipset details for the Xiaomi Watch S1 Active, it's difficult to assess performance. The Ulefone Watch Pro's processor is also unspecified. However, Xiaomi typically equips its smartwatches with capable processors for smooth operation and accurate fitness tracking. The RAM capacity of both devices is unknown, but sufficient RAM is crucial for handling notifications and running multiple apps. Thermal management is also a question mark for both, but a focus on active use for the Xiaomi Watch S1 Active suggests a design that can handle increased heat during workouts.
Battery Life
The Ulefone Watch Pro's battery capacity is unknown, but its wireless charging capability offers a convenient top-up option. The Xiaomi Watch S1 Active's battery size is also unspecified. However, Xiaomi often optimizes its smartwatches for efficient power consumption, potentially offering longer battery life despite a smaller capacity. Wireless charging, while convenient, is generally less efficient than wired charging, meaning the Ulefone Watch Pro might take longer to reach a full charge, even with a higher mAh rating.
Buying Guide
Buy the Ulefone Watch Pro if you value the simplicity of wireless charging and a potentially lower price point. This watch is ideal for users who want a convenient smartwatch experience without the hassle of cables.
