Charge 3 no charging, no HR measure, no green light sensor

[PamelaBollat]

Hi all...

I bought my Fitbit charge 3 last April. Always worked fine. 

This Monday, it started showing too high (very high) heart rate measure (150-180) without working out... compare to my regular HR (50-60).

I try to turn off, on... reset... turn HR off, on... 

It didn’t work. 

Today (Wednesday), the battery drain faster than usual, it didn’t charge and the battery icon went crazy, from 73% to 50% to 34% and back to 50% in less than a minute. 

Also, the green light in the sensors stop working, then no HR measures. 

I try to do all the suggestions in Fitbit community, but still no working. 

What should I do?

Thanks

I have a very similar experience you. My fitbit has ALL of your symptoms, plus 5 black lines across, vibrates itself for a minute all of sudden, the sensor button not responding, battery drains within hours.... and cannot track my sleep at all.

It worked perfectly fine 1.5 weeks ago, and all of sudden all problems popped up... I am so helpless on it and wonder how it could be fixed.....
