The SpO2 sensor uses significant battery life. This is why is princely only enabled during workouts and sleep, but it can be set to run nonstop or not at all. Double check that setting.

My 945 is pretty close to advertised when I’m not too active.

Yeah I have this disabled. I’ve chatted with their support team several times and they’ve confirmed my settings are about as low-energy as possible (aside from disconnecting from my phone, which would defeat the purpose).
