The automatic tracking options are a bit hidden, but extremely powerful if you aren't happy with automatic tracking. I think I was awake until at least 3 or 4 AM, and I woke up well before 8 AM. While the Charge accurately recognized that I got up in the night on June 5 and stayed awake for about two hours, it didn't record that I still couldn't fall asleep when I returned to bed. I was initially happy with sleep tracking, but over time, I noticed that the Charge 4 is easy to confuse. Needless to say, the battery was dead when I returned to the tracker a few hours later. On one occasion, I didn't pay attention when I attached it to the flimsy 3-pin charging claw and didn't align it correctly.

The most annoying aspect of the Charge 4 is still charging, though. I feared that I might run into the dreaded Fitbit Bluetooth issues, but to my delight, that has not been the case - notifications are synced almost instantly, and the few delayed messages I got can be blamed on Android's battery management rather than on Fitbit.

I've left the Fitbit Charge 4 on my right wrist over the last month after publishing the review to get an even better picture.
