My fitbit sense battery won't last more than 2 days

[Lore13]

I got my Sense just a few months ago, having had different fitbit watches over the years and absolutely loving them. Unfortunately this fitbit's battery won't last more than 2-3 days. My husband got his Sense same time with me and his battery lasts 5-6 days, as its normal and advertised! What is the issue?!?! I checked the charging cable (as seen other ppl had issues with charging cable/port) and even switched charging cables with husband but my Sense is still loosing charge in same way. I charged it last night before bed and placed it on my wrist and in the morning was already down to 65%. I am really unhappy about it...I used to always praise Fitbit to everyone in regards to battery life, and even got a few of my friends to switch from apple to fitbit! Please advise! Thank you

HI @Lore13 - this is most likely not a watch battery problem but one of features being used.

Snore detection and SpO2 tracking may be on and they can use upto 4 days of the battery life alone.

See more details in How to resolve the Major issues causing short battery life.

Had SpO2 on previous watch and battery life was never a problem...also I checked all the settings against my husband's and we have same settings and his battery life is 5/6 days and my battery life is 2 days.

I agree with your Lore13. I have my second Sense (the first having been replaced) and both of them have awful battery life. This is supposed to be a smart watch. If I want a watch which doesnt have features, I would buy one that ticks...
