The Power of Bluetooth 5.3
Step up your connectivity with the latest Bluetooth 5.3 standard. Driven by the JieLi JL7012F6 chipset, the P81 offers faster pairing, lower power consumption, and more stable audio for your Bluetooth calls. Whether you are using the built-in speaker for a quick conversation or summoning the AI Voice Assistant to check your schedule, the experience is smoother and more responsive than previous generations.
Bigger Battery, Better Durability
Never worry about the "low battery" warning mid-day. The P81 features an upgraded 300mAh battery, offering a significant jump from the 230mAh found in the P71. This translates to 5-7 days of daily use on a single charge. Combined with a rugged IP68 waterproof rating, the P81 is built to survive rain, dust, and intense workouts, making it a truly "worry-free" wearable.
