a few weeks ago the sense battery started to last less and less.  it is currently lasting about 2 days tops.

This is used with Android  samsung galaxy s21ultra 5g.

If you have snore detection turned on, that is a big battery user, best used just a day or 2 at a time.

Welcome to the Fitbit Community, @NiffinMudd. Thank you for letting us know that your Sense battery is lasting less and less. 

Let us know if you use snore detection and confirm that you have followed the steps of help article: Can I extend my Fitbit device's battery life?

Thank you for your help @JohnnyRow.

Keep on visiting the forums.

i do have it set to short time out.  I do not use notifications.  I do have SPO2 and Snore turned on. but i could turn that off. Just got Cpap.  my snore was near 90 dB  and alot of apnea.   And yes. the snore app was around the time i noticed i dropped to 2 days battery life.

Thanks for getting back to us and for the clarification @NiffinMuddintoe. You can try turning the snore feature off but if it's useful for you, I  would recommend charging your watch as needed.

@NiffinMudd  or @NiffinMuddintoe   I expect it is definitely the snore detection.  I think that is most useful for people who don't have any idea whether or not they snore, or how much.  I suggest using it for a couple of nights to get a baseline; then turn it off and try again briefly in a few weeks or when you have made changes that you think might affect your snoring amount.

My sense is less than a week old and I have had to charge it every morning from day 1. 

I'm ready to return it. The paper that was with it said it had a 6 or 8 day battery life.

Welcome to the Fitbit Community, @Mcateehardy. Thank you for letting us know that you have to charge your Sense every morning. 

I know how frustrating this could be and please check: Can I extend my Fitbit device's battery life? help article. Snore detection and display on all day long can drain the battery faster.

Why would I have to turn OFF the very apps I bought it for?
This makes no sense. If I need to turn them off to extend the battery life,
then I have no use for the watch at all.
So, I am requesting a return.
Thank you,

Thanks for getting back to us and for letting us know that you´ll return your watch @Mcateehardy.

Try turning display always on OFF and check how long your watch´s battery lasts.

Have a nice day.

My sense battery sucks, it drains so fast, I charge every other day. I am using Samsung galaxy S21 ultra 5G too. any solution?

@AJKhan 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.

A warm welcome to our community @AJKhan. Thank you for letting us know that your Sense battery drains every other day. 

@eezeepee has mentioned an important battery drainer: snore  detection. Please follow his advise and let us know how it goes.
