Battery drainage

I have a Samsung phone and have to charge my fitbit sense every other day. I thought the charge was to last longer.

Depending on the age (battery wear condition) of your Sense you should get between 5 and 8 days battery life if you're not constantly activating the screen. My screen timeout is set to 10 secs and normal brightness. I currently get a maximum of 8 days out of my Sense that is only 2 or 3 months old. Some say the the blood oxygen satuation SP02 app can cause battery draining if you use it. I briefly ran this app on an Ionic before I found no use for it. No battery issues that I noticed using it.

First thing I would try is disconnect the Sense from your phone and let it free run for a couple of days to rule out any constant poling from your phone/Sense draining it. If this makes no difference then it's time for a factory reset of your Sense and set it up/pair it again to your phone. 

I would suggest uninstalling the app from your phone as part of the Sense reset if you go down that path.

If you believe it may be the phone, then uninstall the Fitbit app and reinstall it and log back in pairing your Sense again.

Plenty of suggestions if you do a forum search, as most issues are not new.

Hi @Mdaviea  - you should be able to get 4 days under normal conditions, that's is without snore detection and SpO2 tracker app which can use as much as 4 of the 6 days.
