battery runs out FAST

[Shmulikg770]

What's the problem with my sence whose battery runs out in a two day.

Screen always on - is off. The microphone is off. Snoring tracking is off. And still battery drops to half after 24 hours.

Hi @Shmulikg770  - there may be a firmware/app issue but first check all the other possibilities How to resolve the Major issues causing short battery life.

Thank you,
Today I removed the SpO2 tracker app as well.
Hopefully there will be an improvement in the battery, otherwise this watch is useless.

What watch face are you using?

A lot of animation?

Do you listen to music, a lot of calls, texts, emails etc?

Trying to eliminate possible causes outside faulty battery.

[Shmulikg770]

No animations at all,
Does not listen to music, does not receive many alerts, and  not replying messages from the watch.

But since I stopped monitoring blood oxygen, it seems that power consumption is more balanced.

Thank you!

It’s a shame you have to remove SpO2 tracker. 
I bought the sense mainly for that feature and the others of course. The must be something else going on.

[Shmulikg770]

Unfortunately, I had to remove it,

fortunately it is a measure that bothers me less.

I have to say that the fitbit battery performance is poor, and if I had known that this was the case I would have looked for another device.

@Shmulikg770 There must be some kind of connection or syncing issue. I would try delete the Sense from the Fitbit app and adding it again or even factory resetting it. Although, mods here are quick to say only factory reset if customer support tells you too.

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. If I turned off SpO2 I would definitely get 5-6 days. I keep that on because it's part of the health metrics. 

I average around 10-12% battery used in 12 hours and 20-25%. All depends if I do an indoor workout without GPS. 2 hours of outdoor workout with GPS used 15% which averages to 7.5% per hours which would technically get 13.3 hours on 100% battery. That's more than the advertised 12 hours. 

Currently I'm at 48% and I was at 90% on Friday at 5 AM.

[Shmulikg770]

That sounds very good,
I have no time to play with the settings again, now it seems to me that the battery is enough for more than a day and a half, for now it's fine.
(After 18 hours, I lost 10% battery, I did not do sports at that time, I am interested to know how much battery consumption there is while swimming).

Thank you so much.

@Shmulikg770 If you really only lost 10% in 18 hours, you should be fine now. That would average to be 7.5 days, which I don't think it'll actually get.

[Shmulikg770]

Thanks,
This includes hours of sleep, and working hours (in the office),
Still does not include sports (walking, running - with GPS) and not swimming.
If it lasts for 3 days - it's great.

Thanks again.
