Time between syncing data

How many days can the Fitbit One store in memory before it starts losing data?

It can hold up to 7 days detailed data. If you delay syncing beyond that it will start holding data at a summary level only and can hold up to 30 days at a summary level before you start losing data.

I have only gone 6 days without syncing , but the data doesn't appear on my Dashboard. I did replace the battery before these days. When I synced it today it had yesterday and today to date, but not the previous exercise on Sunday & Saturday. Why would that be?

@Hamie thanks for joining us! That's weird. I'd recommend syncing your tracker once again and finally perform a restart:

1. Plug your charging cable into your computer.
2. Plug your Fitbit One tracker into the charging cable, making sure that the gold contacts on your tracker align with the gold contacts in the inside of the charger.
3. Hold down your tracker's button for 10-12 seconds.
4. Remove your tracker from the charging cable and press its button until the screen turns on.

Also, just like @SteveH said, most Fitbit trackers record detailed minute-by-minute data for seven days and can store daily totals for up to 30 days.

Let me know how it goes. I'll be around!
