If you use the Amazfit Active 2 for your workouts, you probably noticed something annoying — strength training didn’t always work right.
Sometimes your reps were wrong, sets were missing, or exercises didn’t get saved at all. That’s super frustrating, especially when you’re trying to track your fitness.
But hey, finally some good news: the latest firmware update 6.1.20.3 is here, and if strength training has been your biggest frustration with this watch, you can finally breathe a sigh of relief—because it’s finally fixed.
Before the Update, Strength Tracking Was… Rough
Let’s be honest—if you’ve used the Active 2 for lifting, you’ve probably had to do a lot of cleanup in the Zepp app afterward.
Rep counts would jump around, exercises wouldn’t get recognized, and sets would sometimes vanish into thin air.
I loved the Active 2 for running and daily tracking, but when it came to strength training? It felt like guesswork. And having to correct every workout manually? That got old real fast.
What’s New in 6.1.20.3 (Even If the Notes Don’t Say Much)
The update doesn’t come with a flashy changelog, but don’t let that fool you. Amazfit focused on fixing what mattered—and it shows.
Here’s how to get it:
- Open your Zepp app.
- Make sure the app is up to date.
- Connect your Active 2.
- Check the settings for firmware updates—it should appear automatically or be available for manual download.
It only takes a few minutes to download and install, and once it’s done, you can rest easy knowing your watch is ready to go.
I Took It to the Gym—and It Tracked Everything Right
I couldn’t wait to test this out. I did a few different routines over the week—curls, presses, bodyweight moves, some barbell work—and here’s what stood out:
- Rep counts were finally accurate. No more random numbers popping up. It was spot-on almost every time.
- Exercise recognition worked. Curls showed up as curls, not some “unknown movement.”
- Rest detection and set tracking felt smooth. It paused when I took a break, and picked right back up when I started again.
- Best part? No edits needed in the app. For the first time, I didn’t have to go in and fix my workout afterward.
The watch was working with me, not against me.
If You’ve Given Up on Strength Tracking, This Might Bring You Back
If you’ve shelved your Active 2 because it just couldn’t keep up with your gym sessions, this update changes everything.
It makes the watch way more reliable—and for anyone who takes their training seriously, that’s a big deal. You can finally trust your data, focus on your sets, and stop wasting time fixing logs after every session. That’s a win in my book.
Any Other Changes?
This update was laser-focused on fixing strength training. I didn’t notice any new UI, added features, or performance tweaks—but honestly, I’m okay with that.
Sometimes the best updates are the ones that make things work better.
Should You Update? 100% Yes
If strength training is even a small part of your fitness routine, this update is a must. No exaggeration—it fixes one of the most annoying flaws in the Active 2.
It turns it into a way more complete fitness companion.
And even if you’re more into cardio or casual use, keeping your firmware up to date is always a smart move.
Final Thoughts: It’s About Time
Look, this update doesn’t feature flashy new features or UI overhauls. But it does deliver something far more critical: a fix that makes your workouts better. And in the real world, that’s what counts.
If you’ve been frustrated with the Active 2 like I was, this is your sign to give it another shot. Update your firmware, head to the gym, and see the difference for yourself.
