charage 3 red light

I woke with a red light coming from under my fit bit.  What does that mean

There is speculation is that the red sensor light is related to SPO2 monitoring that has yet to made available to us. Does it stay on? If not, then I wouldn't worry about it - there are many other posts where this has been spotted.

My battery dies in 5 hours, due to this red light. I have tried rebooting and changing my clock face but still not winning. What could possibly be the problem?

I had the red light flashing and after checking with the community I ignored it and it never happened again.  Fitbit techies didn't know the answer but they heard of it happening.  I know this doesn't help, but you are not the only one.

                      Good luck, Ray

I am having an issue where my Fitbit Charge started flipping out, flashing between screens and vibration like crazy, then became unresponsive. I did a customer support chat, restarted and it stopped flipping out BUT now there is a bright red light. Not a blinking light but a bright unblinking red light which doesn't go away. My battery is also draining super fast, like in hours not a week like normal. I have made another chat and 2 phone calls with no solution. I was supposed to get an email to fo a "battery drain test" or some such thing, which hours later and I still have yet to receive. Super frustrated.
