Charge 3 battery and exercises issues

[SunsetRunner]

Bought the Fitbit Charge 3 Feb this year it worked well for a while. However now I have found it to be consistently unreliable and the battery life is declining at pretty fast rate. The manually activated track activity works from time to time, sometimes it is accurate, sometimes it just quits part way through for no reason and sometimes it records nothing other than HR. I have tried all the resets, re-pairing, update the app, delete the app, re install the app, reset the Charge 3. Not sure what else to do but the problem persists and kind of makes the device useless. Any advice/ideas?
