Sense 2 battery drain

[MJWT]

After 5 months my battery lasts only 2 days. Even on sleeping mode. There is no option to disable bluetooth, what can I do to save the battery?
the first battery load last a week the second only 4 days and after that just the 2 days. Within a year this watch will be useless. 
I regret buying the sense 2 instead of the versa 2

Hi @MJWT - you can turn Bluetooth off, on the phone and this would be a good test to make.

I have seen a watch display wake every time it syncs (about every 15 minutes) this can use the battery unexpectedly with Bluetooth off, it won't. 

And if it is experiencing syncing issues they will also stop, and the battery may last longer.

However try restarting by holding the watch button for 10 seconds till it blanks or vibrates and wait for the logo to appear and for it to start.

The other thing to try is changing clock face, sometimes the watch can reboot unexpectedly and unnoticed this drains the battery a lot. This may be related to the watch more than the clock face but may help.

Of course your watch may have a hardware issue also.

Perform a standalone test to verify.

With Bluetooth off and a 95% charge, restart the watch, put it in Sleep mode and place face down, with the straps out of the way where it can't detect any movements (so the lights don't flash). Leave for 4 to 8 hours and see battery degradation. Something like less than 1% per 2 hours assuming the watch face is not doing special things should be attained.

Thank You,

just restarting did the trick. I Will still keep it on sleeping mode because the battery will last longer that way. But when not on sleeping mode it doesn’t sync all the time but the battery drains faster. 
thanks for helping me out!

I updated the os of my Sense2 the other day. My battery literally now drains from 100% to 0% in about 5 hours. Any ideas?

Maybe try a restart of your Fitbit? 
Hold de button untill you see a flashing logo.
