Battery dying very quickly

[numbrkar]

Please tell me I'm not the only one with this problem. I got a notification three days ago that my battery was low. It got down to about 18% before I charged it back up to 99%.

When I got home from work today, it was at 58%. An hour after that, I went to the gym (down the street from my home). I started my workout and noticed my battery was only at 5%. I got no low battery notification. It's now dead.

Make it make sense.

Welcome to the Fitbit community, @numbrkar!

Sad to hear you're having issues with your Charge 6.
As a first approach to hopefully get things fixed, I'd suggest restarting it. Before doing so you should make sure you've synced your device to not lose any data tracked so far. Also you should verify that the charging contacts on your device are clean and the charging pins on it's charging adapter are clean as well and can move flawlessly. In doubt please have a look here:

Next please closely follow these instructions as timing is crucial for this procedure:

1.) Connect your Charge 6 to the charging cable which has to be connected to a reliable power source.
2.) Press the button located on the flat end of the charging cable 3 times within 8 seconds(!), holding each press for about 1 second(!).
3.) Wait around 10 seconds until the Fitbit logo appears on your device's display.

I'd like to point out that it sometimes requires more than one attempt to restart Charge 6. So, before throwing the towel, please give it another try.

If that really won't work for you, please try if changing your device's clock face will get it back to working order. Here's how to do that:
