Bip S

I use an AmazFit Bip at times. Slow to acquire satellites, not nearly as nice as the T-Rex, but quite inexpensive. Basically just records the GPS route and keeps track of time; no mapping.

True. My Bip has taken some beatings, but not nearly as robust as the T Rex.

>a lot of smartwatches had to be recharged every few hours, not just every day My Amazfit Bip had about 3 weeks of battery life, Amazfit GTS3 had 2 weeks, and the current Amazfit Bip 5 have 7 to 10 days.

Amazfit BIP was very nice. Still miss that MIP screen. Had BIP U Pro, T-rex Pro, T-rex 2 and their screen wasn't nice as BIP's MIP. And yes, Garmin is years ahead of Amazfit in terms of software..

I wouldn't use it for any scientific research. To be clear: I've never used it. I've used the Xiaomi S1 watch (high end), the Amazfit Bip, Band... something, and I have the Amazfit Band 9 Active right now to tide me over because the backlight on my Garmin Vivoactive 3 has died. (And because it cost 40myr delivered ($10usd)) The two bands - Bip have been dubiously accurate. Basically fine, I guess.

Kinda regretting getting the round early. I'm used to the square Bip and this feels sexy.

I sleep with my trex 3 pro (48mm) which is very bulky. I think that even though it is big, I progressed over the years from the mi Band 3, to amazfit bip, to GTR4 and then to this one. The progression makes it easier

Amazfit bip. Battery lasts 14ish days, does everything an Apple watch does and does the sports tracking. I love mine. I usually use the walking/hiking feature. I hit the start button for the workout and it let's me know when I've hit a mile, how long it takes me to do a mile etc. It can show where I've gone. The amazfit pro speaker is better than the bip when using the phone function. It does not come with cellular. It only has calls coming through with Bluetooth connection. But you can answer calls and talk over the phone using the watch.
