Can the Redmi Watch 4 continuously monitor SpO2 while swimming without having to remain still and alarm if low?
The Redmi Watch 4 supports 5ATM waterproof. There is no need to take it off for swimming in the pool. You can enjoy playing in the water. But it is not suitable for hot water shower, hot springs, sauna, high-speed water movement, and other scenes to wear.
Does it help?
