Display Comparison
Given the lack of specific display data for the Xiaomi Watch S4, a comparison relies on brand positioning. Apple Watch Series 9 likely features an LTPO display, enabling variable refresh rates for improved battery efficiency and smoother animations. The Apple Watch’s display is also known for its excellent color accuracy and high peak brightness, crucial for outdoor visibility. The Xiaomi Watch S4, positioned as a budget option, likely utilizes a standard AMOLED panel, potentially with lower peak brightness and a fixed refresh rate. Bezels are also likely to be more prominent on the Xiaomi device.
Camera Comparison
Neither device is primarily marketed for its camera capabilities. However, the Apple Watch Series 9 does not have a camera. The Xiaomi Watch S4’s inclusion of a camera, even a low-resolution one, offers a niche functionality for quick snapshots, though image quality will be limited. This is a minor differentiator, unlikely to be a deciding factor for most buyers.
Performance
The Apple Watch Series 9 is powered by the dual-core Apple S9 chipset, a significant upgrade over previous generations. This chip enables faster app launch times, smoother animations, and improved performance for demanding tasks. The Xiaomi Watch S4’s processor remains unspecified, but given its price point, it likely utilizes a less powerful chipset. While sufficient for basic smartwatch functions like notifications and fitness tracking, it will likely struggle with complex applications or demanding tasks. The Apple S9’s architecture allows for on-device processing of Siri requests, enhancing privacy and responsiveness, a feature unlikely to be present on the Xiaomi Watch S4.
Battery Life
The Apple Watch Series 9 offers wireless charging and can reach 80% charge in 45 minutes. Battery life is typically around 18 hours with normal use. The Xiaomi Watch S4’s battery capacity and charging speed are unknown. However, given its likely lower power consumption due to the less powerful chipset, it may offer comparable or even slightly better battery life than the Apple Watch Series 9. The lack of fast charging on the Xiaomi Watch S4 could be a drawback for users who need to quickly top up their device.
Buying Guide
Buy the Xiaomi Watch S4 if you need a stylish, functional smartwatch with essential fitness tracking features and are not reliant on the Apple ecosystem. It’s ideal for Android users or those seeking a secondary smartwatch. Buy the Apple Watch Series 9 if you prioritize advanced health monitoring, seamless iPhone integration, a mature app ecosystem, and are willing to pay a premium for the best possible smartwatch experience.
