Fitbit Charge 5 - problems

[t1atum]

I have had several problems with my Fitbit 5.

First, I can barely see the LED display - it's useless to view time during the day and just barely visible during the night. How do I fix?

Second, it has problems registering my sleep pattern. A few days back it was fine but last night not at all - even though I slept well. Any suggestions?

Welcome to the Fitbit community, @t1atum!

Sad to hear that you're having issues with your Charge 5.

Have you already tried increasing display brightness on your device? Here's how to do that:

Regarding your observations on sleep tracking, I'd suggest setting up a sleep schedule and a sleep goal to improve sleep tracking results. You might also want to switch sleep sensitivity to improve sleep tracking with your device. To see how to do all that, please take your time having a closer look here:
