Long battery; but wrist HR tracking is inconsistent.

I just switched to a Garmin Venu 3s a couple months ago from a Samsung Watch 6.. My god it's amazing. It took some getting used to, but I just select the strength workout and it can figure out what exercise I am doing (for the most part). It's wizardry. They aren't cheap, but the battery is amazing.
I also have the Venu 3s and I love it!
I love the Venu 3s. It has metrics like V02Max and does all the tracking I need as a cyclist.

Switched from Apple Watch to Venu 3s, and I have no regrets. When weight lifting it counts your reps and presumed weight activity then allows you to input the weight lifted with each activity. The battery life is phenomenal. Just today I have done 200 active minutes and it’s gone from 83 to 81%. Steps are another thing. It’s a lot more precise. Active calories are realistic. Apple would say I would burn 700 active calories after a 5k run and 30 minute workout, versus garmin has a realistic count of around 300-400 with comparable activity. Sleep tracking is amazing. But honestly I can’t praise the battery life enough. That alone is the selling point. With my Apple Watch it wouldn’t make it through my 15k and then strength training before giving me a “10% left” notice. It was an atrocious effort to plan my runs around my battery life.
I just made the switch from an Apple Watch Series 8 to a Garmin Venu 3s. I am so so happy with it. I am still figuring it out, but loving all the features and also love not having to charge it so frequently!
