Weights Session and Calorie count totally off on Versa 2?

[dave_in_ni]

I've owned the Charge 2, Blaze, Versa and now Versa 2, so I know roughly how much a weight session should burn.  The Versa 2 always undercounts.  I decided to test this today with my old charge 2 on one wrist the versa 2 on the other.  40 min session the Versa 2 says 90 cals, The Charge 2 163 cals, Okay I know its impossible to be totally accurate lifting weights but it should at leas be close, its no where near.

Now on walking running etc its fine.

@dave_in_ni I hope you're doing well! Sorry for the delay in my reply.

Let me help you with your Versa 2 under-counting calories for your Weight sessions. I suggest you clean the back of your device with cotton and rubbing alcohol and restart it. Turn the heart rate off, save and sync then turn it on save and sync again. Also check these tips to improve the heart rate reading on your device. You can also try manually logging your activity.

Let me know how it goes.
