Fitbit Versa 4 perfect
I have a Fitbit Versa 4. My main complaint is that I have to recharge her every 3 days.
I legit had to bite the bullet and get a portable watch charger for the times I just didn’t have time to charge it before work. (I have a variable schedule so I can’t just charge it at the same time every day, and charging it when I shower the night before leaves me with at best 70 ish battery when I wake up—this is not always enough and sometimes I end up cutting it real close.) To be transparent, I have a refurbished S7 with 84% capacity, so it’s certainly not at its peak, but it’s also a rude awakening coming from fitbit. My old blaze I only had to charge every 2-3 days, the newer versa 4 I could get away with 4-5. But I eventually had to ditch the versa because notifications were inconsistent, I’d reboot it to fix it and it’d get stuck in a reboot cycle, and I got tired of not being able to control my music with it like I could on the blaze. (Unless you specifically use YT music… I don’t, lol.) I 100% get there are reasons it drains faster than other stuff but it’s still wild to me how much faster it goes than literally anything else I’ve owned.
I have a Versa 4, just over 18 months. I shower in it every day and swim in it once a week. It gives me a good account of my sleep and activity and tracks my heart well. It has accused me of running twice, when I've been doing a bit of vigorous washing up! 🙃 otherwise I've no complaints. I forgot to mention - it charges to 100% in just over an hour and it lasts 6 days. Also I charge it at 17 - 15% if that helps anyone.
I just use a Versa 4.
Not the versa 4. You can get stretchy bands to wear it on your arm instead of your wrist, but if you do, the heart rate tracking really doesn't work very well. Also the mechanism to connect the band to the watch is not something I would trust to stay fastened in full contact. Their skating activity is also very inaccurate, it tries to track you by gps which I suppose might be fine for trail skating, but not for going around in a circle.
