Sense 2 battery is draining overnight

[Kitty-Kate]

I got a new Sense 2 on Xmas day and it was fine for the first few days, but for the last two nights keeps losing about 60 to 70% of a nearly-full charge overnight.  Both nights it was at about 90% when I went to sleep then around 20% when I woke up - but it seems fine in the day.  any ideas anyone?  thanks

Hi, @Kitty-Kate , both SpO2 measurement and snoring detection use extra battery capacity.  If you have either of these turned on you may want to experiment with turning them off and see if that solves your issue.

Thank you. I don’t think I have them turned on but can you tell me how to check /how to turn them off?  Have been looking for the snore thing to turn it off but couldn’t find it. Thanks v much.

@Kitty-Kate Sense 2 doesn't support snore detection hence you can't find it 🙂

I turned off the SpO2 and all fine now thank you!

I am having the exact same issue. The spo2 is in but has been the entire time. I am ready to return it and get an Apple Watch.

How do you turn those off?
