sense battery

Why is the battery on my sense only lasting about 2 days??

Welcome to the Fitbit community.

What are your settings? 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.

Also, keep in mind most battery claims for devices are in ideal conditions and are more of a maximum battery life rather than an average.

FYI: The search at the top of the community is very good and useful.

Hi @jgwoodward  -  as @eezeepee  says the Snore and SpO2 use about 4 days per charge so if you only get 2 days turning those off will give you nearly 6 days autonomy.
