Hello! I started researching my wife's fitbit Sense as hers was dying within a day and couldn't figure it out before i had to leave on a business trip from portland to Denver. Upon my arrival to Denver, the auto sync time wouldn't sync from pacific to mountain time so i had to 1) hard reset it 2) unistall and reinstall my fitbit app and 3) pair my phone back to fitbit and 4) restart my phone. FINALLY IT SYNCED THE TIME! BUT....my sense went from 100% at 7am to now 17% at 9pm... I AM HAVING THE SAME PROBLEM A WEEK LATER WITH MY SENSE AS MY WIFE. please help! I have done everything I can think of! I'm also getting tired of spending several hundreds of dollars every 18 to 24 months for NEW FITBITS...
Best AnswerNot sure how well this ties in with your experiences, but snore detection is a big battery hog if turned on. Best used just a few days at a time.
