Sense battery lasts no longer than 5 hours, suddenly

[Keavis]

As the title says, very recently my battery (as of about three days ago now) lasts under five hours from 100% to 0%. Initially I didn't know that it had a problem, since my charger broke, but I have a new one now, and never can go a full day on a full charge.

I have a default clock face, spo2 is off, screen wake is manual, and it still drains incredibly fast. I read that battery life can be compromised if the watch has been submerged in water, but I haven't done anything more than clean up the underside with some isopropyl alcohol (which should be fine).

I've only had my sense 1 since June of 2022. Most people I know that have had one, their battery lasted them for 2-3 years.

Any thoughts/help? I can't afford a new one at the moment, otherwise I would just upgrade to a sense 2 or a pixel watch.

5 hours is an an issue. 

Try turning off the phone's Bluetooth and Shutdown the watch After 10 seconds place the watch on the charger, to restart it and fully charge it and see how it goes.

Make sure snore detection is turned off and some of the other apps or functions you do not use are deactivated. May give you some additional charge.

Tried all of these, and no better, maybe even slightly worse when I turned off snore detection? I think the battery is just suddenly... Dead, for lack of a better word.

I also tried factory defaulting it last night, and I thought that it improved, but after charging it to 100% at roughly 10pm PST, it was already at about 60% a bit after midnight.

Hi @Keavis - it would seem the watch has a hardware fault often caused by water getting in.

If under warranty it can be replaced but if not, note later models don't have all the features this watch has.

Same. My Sense is bricked too. I do not get it wet. It went from 6 days of battery life for 2 years to 2 days a couple months ago, back to six days after deleting a couple of unused apps. Then two weeks ago, battery life mysteriously dropped to one hour. Fitbits response...buy a new one for 35% off. Nope.

My premium subscription will cancel on the 22nd and I will be done...especially after seeing so many posts with so many people having the exact same issue and fitbit lame trouble shooting advice (turn it on and off...yup that's it) and offering a lame 35% off. I mean seriously. I've paid what $300 MOL in premium fees over the last several years and would have kept on doing it happy as a clam with a working device. I have read that Google is phasing out the Sense and another similar model (that had bricking issues with the last software ipdate too). and why would I go spend money on a new device when ive read newer devices are having the same issue. Add the crappy app update to the mix on top of the software issues and why would I go spend money on a new device only to worry it will brick too? (On top of having ro replace all my additional bands and protective face covers that are now wasted.) 

I guess you could say as a customer, I too have tasted a lemon and the experience has soured me.

Do better Fitbit. Do better Google.
