Sense won't hold a charge

[JayMEG2430]

My fitbit sense is 6 months old and I could go 3 days or longer without needing to charge. I use it daily to track my exercise and that's it. No other apps used on my fitbit, not connected to my phone's bluetooth unless I manually connect it. Within the last day or two, my fitbit's battery drains in less than a 12hr day after being charged to 100%. App and fitbit are up to date.
