How to change EOV settings?

[tuttifrui]

Some time ago I activated the oxygen variations settings, but as I understand it doesn't work on the charge 2. Now I can't find the settings to turn it off!

As far as I know, there are no settings for it.  If you have the appropriate tracker and get sleep stages, you get it; otherwise you don't.

I have seen some people without it saying they do still get the display area for it, but with no data.  I think that is just an app issue with no current way to avoid it.

Hi @tuttifrui, it's nice to see you again participating here in the Community Forums, welcome back.

Thanks for the information that was shared in your post. Let me share that, just as our friend @JohnnyRow mentioned in his post, the Estimated Oxygen Variation feature is available on Charge 3, Ionic, and Versa series devices only, therefore, you're unable to change the settings of your Charge 2 in order to activate or deactivate this specific function. To learn more about this, please check the information that's specified on: How do I track my estimated oxygen variation in the Fitbit app? and let me know if you have any additional questions.

I'll be around.

Hi…

Just reading all this now as I have bought a Charge 5 and what a rubbish battery! I like the look and feel but have now turned virtually everything ‘off’ (attempting not to drain power - ridiculous) - and I want to turn off this EOV sleep thing.  How do I do this? I am losing over 30% charge at night time! 
i can’t be charging it every day ☹️
