Sense battery life

[HatsGirl]

Upgraded from versa 2 to sense. Very disappointed so far. I have had to disable all the special features I purchased the watch for because the battery is draining in a day.. sp02 disabled, alarms disabled, now the skin temp isn’t registering. Thinking about returning this and going back to my versa. I charged it once a week. I went with the Fitbit over the new Apple Watch because it was supposed to hold a charge for 6 days. Thoughts??

So in 24 hours you go from 100% to near 0%? That's definitely way too fast even if you had always on display, snore and noise detection, and SpO2 all on. 

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.

And that's with one or two 1-hour workouts.

You might either have a bad battery or some kind of sync/connection drain. Have you tried deleting your Sense in the Fitbit app and adding it again? Be sure the snore and noise detection is actually off as it does drain 20% over 7 hours for me compared to 7-9% with just SpO2 on. If you've done all that, contact customer support.

It’s frustrating to turn off all of the features I upgraded for. I’ll turn off the “extras” and see what happens. Thanks for the tips 🙂

@HatsGirl Keep in mind most battery claims for devices are in ideal conditions and are more of a maximum battery life rather than an average.

Although, I think Fitbit's claims for their regular trackers seem to be on par to their claims.

I already had these settings and it's just been the last week that it's draining in about 24 hours

I have had my Sense less than a week and am having the same issue. I don’t have any of the “extras” and the display is never on. I just fully charged it and checked the battery and it’s drained 6% in the less than 5 minutes since fully charged. Not happy at all.

@branmuffin75 Yeah that's not normal at all. Have you contacted customer support? I would have to use a ton of GPS to kill the battery within 24 hours. I just did another battery life test and this is what I got:

Day 1

5:15 AM - 99%

5:15 PM - 88%

Day 2

5:15 AM - 77%

5:15 PM - 65%

8:00 PM - 61%

Day 3

8:00 AM - 49%

8:00 PM - 40%

Day 4

8:00 AM - 21%

2 hours of outdoor workout with GPS used 15%

10:45 PM - 5%

So that's 3.7 days worth. GPS appears to use about 7.5% per hours which is better than it's advertised 12 hours.

@KellyMc024 I noticed the first few percent might appear to drain quickly. Keep track and see how it does every 12 hours like I did above. My Sense seems to drain around 11-12% every 12 hours or 20-25% every 24 hours.

Thanks @eezeepee! down to 59%. Time to reach out to support!

@KellyMc024 Forgot to ask and I know you said "extras" are off but 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.

[KellyMc024]

Yup those are my settings now and I don’t use SpO2.

I updated the app and this seems to have helped
