Hi @Dgflame  - your battery can last anything upto 6 days but if you use a lot of features it can be a lot less, snore detection and the SpO2 tracker app  can consume upto 4 of those 6 days.

As regards charging it needs a good 5v usb supply and consumes around 300 ma, except when WiFi is on and can use 340 ma for a brief moment.

A pc usb can be a good source.

thanks for your reply, I have found that my Fitbit sense battery works max for only 2 days only I have doubts about my battery is it in good condition or defective?

@Dgflame  - it is most likely only a usage issue. I have an original Sense from 2020 and the battery is fine with the proper settings and charging once every 5 days.

Better to check which features or settings need adjusting if you want charge less often. See How to resolve the Major issues causing short battery life
