My Fitbit Sense doesn't hold a charge pass 3 Days. I am using an Android Phone.

[t2759ls]

My fitbit Sense needs to be charged every 3 days. I turned off everything except my phone and message  notifications and don't have the display on always on. My Ionic last 6 or more days and this was a replacement for that device. I  have to charge twice a week.  I have updated my Sense and the app on my Android phone and it still has not made a difference.  I did chat with someone and they told me that if I updated the software the issue would be resolved.  The issue has not been resolved

I should have gotten the Versa 3.  

Can you tell me what is being done to correct this issue?  If it is not being corrected is fitbit replacing these defective devices?

Hi @t2759ls Unfortunately those are not questions that can be answered on the forums. You would need to contact Support again for any hope of a reply.

Have the same problem, what is going on???

Hi @t2759ls , @Mary1948 , - in general short battery life between charges can be due to the use, or over use, of certain features.

Have a look at the main issues How to resolve the Major issues causing short battery life

I noticed something similar since last FW update. I don't use notifications and wear watch only at night and during activities. During day, the HR sensor is off which should (in theory) add even more lifetime. Before, the battery could last (with same usage) lot longer. I took closer look at battery consumption and after 72hrs (3 full days) battery dropped to 28%. During that time I had only chance to run twice with GPS (50 and 40min). It's unlikely my watch would last 3 full days if I did more activity (tomorrow I have planned long 2 hours run so I may need to recharge it before). So far, I tried everything (thanks @Guy_  for all advice👍) and no success. The watch is nearly 2 years old so it could just be the battery deteriorating. Yet, I still think it's the firmware as ithat sudden change in power consumption matches time I updated the watch.

Check to see if you have the snore detection enabled. It keeps the mic on all night, and battery life is right around that 3 day mark with it enabled.

[t.parker]

@HyTeK that's very first thing I checked knowing that this is one of the most powerhungry feature. Never enabled it but there were cases that after update users have found it magically turned on. I keep monitor battery level, recharged it yesterday, from 8:30pm 100% went down to 97% at 11:00pm and this morning 08:45am shows 84%. I think after last recharge it drains even faster. Days of my Sense are counted.

I too have noticed a significant drop in battery life after the latest FW update.  I can barely make it a full day if kept in sleep mode, otherwise I need to recharge the watch midday to avoid total shut-off. Disappointed as I had the blaze prior and right around the 2yr mark it experienced similar issues. This does make me skeptical as the degrade in battery performance was immediate and drastic and seems to also coincide with the new arrival of the sense 2.

[Guy_]

Just in case the bug was in the firmware update process rather than the firmware itself, consider a full factory reset to confirm.

Beware the factory reset can fail which may kill the watch. If you decide to do it from the watch Settings, About Sense menu, wait several minutes for it to complete and display the initial setup screen on the watch.

Then place on the charger, near WiFi and phone and no other Bluetooth devices and proceed with Set up a Device in the app and redo notifications and any special settings.

It is unlikely a battery will degrade rapidly from a FW update other than over use (possibly internal processing malfunction).

[t.parker]

@BroadwayB very unlikely 🙂 Let's not look for conspiracy theories here. Fitbit doesn't seem to test releases of FW (or phone app) thoroughly. Not the first nor the last time that happens. My old Ionic kept the power way beyond 2 years (despite getting water damage before which resulted in glitching display, yet other functions still worked). I still have the old Charge 2 and the battery lasts very long. It's the first time any Fitbit device I own has issues with power consumption. After recharging my Sense, the battery went down from 100% to 46% within 42hrs (including 2hrs of running with GPS). This is quite bad. Interesting thing is that when I checked the battery life before and after my Sunday long run (1hr30min) it was 85% down to 72%. This is 13% which is normal (usually 1hr with GPS is ~10% of battery, that's expected). The increased battery consumption appears mostly during the night (tonight, 95% to 85%) and when idling (simply, when doing pretty much nothing).

If it's battery dying then it's a very short lifespan for the battery (my old Suunto watch, older than Sense still lasts days on a single charge, with no visible signs of battery deterioration). My Fenix 7 runs on a single charge since the 6th of September and now it still has 51% (with more extensive use than Sense). I'm really hoping the problem is in the FW not in hardware and (maybe) Fitbit will release one last update fixing it (although I think that Sense lifecycle sad ran its course).

I am SO DISAPPOINTED in the recent fitbits since Google took over.  My first one lasted 4 years and these last just long enough to pass the warranty period.  As I was waiting for my new Fitbit I borrowed a Versa 2.  With that "update Fitbit" in my face every night I synced  I updated it.  It totally CRASHED with no battery life and I could barely see the screen.  iI was immediate.  Fitbit support could not help and  is taking NO responsibility for this which is SO MADDENING!  I now have to replace this borrowed Fitbit and am FURIOUS!  This is the last Fitbit I will have.

I want to urn the whole Fitbit community but do not know how to do it.

[goingstrong]

My reply took two weeks after I went through the chats which are 45 minutes long as well.  No one there could help. My Fitbit crashed after a software update. Fitbit said they could not help, ARE YOU KIDDING?  Everything worked fine until the update.Are they trying to crash every Fitbit that has been used for more than a year so we have to keep buying new ones?  Mine last just past the warranty periods. I have so many unusable ones. Sigh!

[Guy_]

Hi @goingstrong - are you able to do a factory reset?

If that fails or doesn't help the good news is the Versa 2 is on offer so less expensive to replace.

It is bad that Fitbit don't accept responsibility for what is their fault

Battery on my brand new Sense has died 3 times while I was sleeping over the past week. I’ll have to track battery usage more closely.

Snoring detection is off. Screen Wake is set to manual. Brightness is set to Dim. Always on display is off. 

Main reason I have a Fitbit is so I don’t have to recharge it everyday. At this point I might as well have an Apple Watch.

Hi @Duobla-A - Have a look at the other main issues How to resolve the Major issues causing short battery life

I get 5+ days from my Sense so it should be possible, double check snore detection in case it got turned on again.

[t.parker]

@Guy_ I have seen the thread you linked before (btw. good job!) and it's kind of scary as it looks like the only way to get the promised battery life is to make sure the watch is turned into a mere pedometer.

One more thing I can think of (and it happened to me) when it comes to nighttime battery drain is random exercise tracking (unlikely to happen for most people but it happened to me). Basically, when the watch is worn on the right wrist and there is a shortcut starting exercise assigned as a long-press of a button then it is possible that the user may activate it during sleep. It happened to me twice and the second time the vibrations woke me up. Funny that starting the exercise tracking doesn't affect sleep tracking. Now, I believe it may be anything, not only exercise but any app assigned as a shortcut that may launch during sleep and drain the battery. Exercise will leave a trace in the activity log but other apps may not and users may never know that activated something during sleep. For people who wear the watch on the right wrist, I recommend disabling long-press (and double-press) shortcuts completely (and then see whether after a few nights something changed about power consumption). For me, activating exercise drained almost the whole battery until morning when I found it out the first time.

@t.parker - that's a good tip for poor left handed people who can't rotate the watch face.

[Guy_]

Btw see if turning off the microphone in watch Settings makes a difference.

[RB0914]

Turn off your SP02, it picks up ambient sound and kills your battery life. 

[Guy_]

Hi @RB0914 - it's true SpO2 is one of the main drainers.

To turn it off remove the SpO2 tracker app and don't use an SpO2 clock face.
