improve battery by changing the heart rate monitor frequency ?

[simology]

I have serious problems with my fitbit sense battery (it lasts me almost a day),
I'm optimizing by disabling various features and apps
for example I disabled (google assistant, call on the wrist, gps in all workouts, lower the brightness level..)
I want to understand if you can disable even more features that I might not be interested.
for example changing the frequency of heart rate monitor
I am not interested in having a constant relivation of the heartbeat for I would like put it at a distance of one minute.

1 minute instead of constant detection

finally if you have other ideas to suggest to save battery thanks...

Thanks for your comment, but i can't turn off bluetooth because I have other devices connected via bluetooth.
I need optimize the battery of my fitbit sense device and not that of my mobile phone
