@Hornet1455 Keep in mind most battery claims for devices are in ideal conditions and are more of a maximum battery life rather than an average. I can get 4 whole days with these settings: Brightness dim, screen wake motion and button, always-on display off, snore & noise detection off, SpO2 on. The biggest battery drainers, especially overnight, are the snore & noise detection and SpO2, but more so the snore & noise. With it on, I lose around 20% over 7 hours of sleep. With that option off, I only lose around 6-8% over 7 hours of sleep. I had it on for over a week and I don't snore and noise is minimal so it wasn't worth the drain. If I turned off SpO2 I would definitely get 5-6 days. I keep that on because it's part of the health metrics.
