I don’t have the updated devices but I’m confident that my calories are low by about 200, as I typically ear above them each day and still don’t gain weight
Same issue for me here. My average calorie output per day since moving from whoop 4 to 5 has gone down by almost 500 calories per day, doing almost exactly the same routine. Ive been using this app now for 2 full years without missing a day and now everything seems to be tracking much lower. Intensity lower, calories lower, effort lower. HAS to be from this update because nothing else has changed for me.

Agree! Especially lower intensities like when Im using my walking pad. I’ll walk 3 miles in one hour and it’ll say I burned 50 calories whereas my Apple Watch or Peloton will say it’s like 250. If I do a 20 minute run at a 9 min mile pace, then the 3 trackers are much closer, saying around 200 for whoop and 240 for Apple and Peloton.

So frustrating! So either the new device is wildly inaccurate, or the last one was.
Glad we pay so much for it.

I walked/hiked 25km yesterday at about 4.3-4.5km per hour speed…and my whoop tells me I burned about 1300 calories in total for the day. It didn’t pick up the activity at all.
Yes. Calories per day is way off! Like really way off. For some time I tracked macros and calories with a third party app to see if I match my daily burned calories Whoop shows me. The result was: It’s highly inaccurate. I lost weight. I do a high training volume each week and can not afford to lose weight. So yes I agree with you: Whoop’s calories are

Completely agree. I get the same canned response from Whoop when I asked them about it.
With my 4.0 I burned more calories during a time where I was recovering from shoulder surgery and mostly inactive. Now that I am running 2x a week and lifting daily, I am burning at least 100 calories less a day. It’s non sensical.
I use my fitness trackers to manage my calorie burn and intake. If it doesn’t improve I will not renew my membership in January.

I’ve had my Whoop for 5 days and was hoping the calorie burn would calibrate. It hasn’t. It’s averaging ~1,500 kcal/day for me.
I consume ~2,600 kcal/day (logged in MyFitnessPal). If Whoop were right, that’s a surplus of ~1,100 kcal/day → ~7,700 kcal/week → over 2 lb/week of weight gain. That’s obviously not what’s happening.
Any basic BMR calculator puts my BMR around 1,500–1,600 kcal/day, which is further proof your estimate is way too low.
This is a shame because accurate calorie burn was the primary reason I bought Whoop—to maintain a slight deficit while still fueling my training. And it’s frustrating to keep getting the same canned responses from your team. This is a critical metric for people paying good money to monitor calories and performance. Whoop needs to fix this.

I have the feeling, that they calc calories like Mi Fitness. Active calories + BMR, but they add BMR only during movements, like steps, exercises etc. Lets say when you dont move for 24 hours, your calories for that 24 hours would be just 0. But BMR is a fixed value, independent of you move or not! That all with whoop is so strange.

What’s even stranger is that when I woke up at 6:30 a.m., my calorie burn was already at 542. Now it’s 3 p.m. and it’s only at 1,000. That means I burned more calories while sleeping. Lol. It’s frustrating that Whoop continues to ignore this issue. I’m still in my trial period and seriously considering canceling and switching to the Oura Ring, which is apparently much more accurate with calorie burn.
