I recently switched from wearing my WHOOP 5.0 on my wrist to the bicep band, and overall it works great, better comfort and seemingly cleaner readings during the day.
The issue is sleep detection. Since switching to the bicep band, WHOOP regularly detects my sleep start time way too early. Some nights I get in bed 1–2 hours before I actually fall asleep, and WHOOP will sometimes count that whole period as sleep. It has been off by as much as 2 hours.
I’ve manually corrected the sleep start time for about two weeks, hoping it would recalibrate or learn from the edits, but it doesn’t seem to be improving.
Has anyone else had this issue with the bicep band? Is there any way to improve sleep detection accuracy other than manually editing every morning or switching back to wrist wear at night?
I’ve had whoop since the 3.0 version (I’m on the MG now) and I’m here to tell you. It’s always done this. And it never “learns” like they claim it does. When I get home and sit on the couch for any period of time greater than 40 minutes (that seems to be the detection window) without getting up, it logs sleep or nap. I thought turning off activity detection would help. It did not. With the Fitbit Air coming out and the ability to finally have a central hub for ALL tracker data streams, I think I’m finally going to jump ship. Also, the steps transferring at the end of the day just causes my step count in Apple health to be way off because Apple health is good at filtering double data as it receives it, when it gets it in batch data at midnight that doesn’t work, so it just adds it to whatever number it already had.
