Fitbit Sense battery only lasting 2 days

[Ale111]

I am very dissappointed with the new fitbit sense.

1)It is not waking up when I want, neither when I move my hand up(I followed all the instructions in the manual), neither tapping the screen.

2)I need to charge it almost every 2 days. 3)The first time when I looked my phone, it found it, but now It can't find it either bwing next to my phone.

4)When I am trying to get out of an excersice or in general to go "back" it doesn't work, and I have to use the side button.

@Ale111 Hi there. Thanks for the detailed information shared. 

I see where your disappointment is coming from. I appreciate the troubleshooting performed prior to posting.

Let's try restarting your Sense for the screen not waking up and not responding at all when you press "back". I'd like you to make sure you're following these tips to extend the Fitbit device's battery life. 

Last but not least, follow this syncing troubleshooting. 

Hope this helps.
