Amazfit makes it official Cheetah 2 Pro

It's a large watch at 48mm but with the display size of the Amazfit Active 2 and T-Rex 3 Pro 44mm. Hmm.... And the Band size is 20 mm. Okay, time to update the Amazfit Watch Guide. I'll do so, during the day. Funnily enough, the Cheetah 2 Pro is heavier than the Balance 2 LOL

Amazfit Balance 2 not working after going to the sea

There are LOTs of failing Balance 2 and T-Rex 3 Pro watches after sea, pool and diving. Not only here but also in other forums. There's an important issue here that should be reviewed u/Amazfit-Bryce

Balance 2 Died at 5 Meters

It seems that Amazfit watches are not as durable for swimming as they were advertised. Same issues occur on T rex 3 pro as number of users reported. However, Garmin is no better in this regard. Garmin Fenix 7 and Epix have been having same problem from release in 2022, and it was not fixed even thei

Amazfit for serious sports training

Amazfit hardware is fantastic. For reference, in the last couple of years I’ve owned and trained with the following (I’m not rich or crazy, but I got really used to having a bunch of devices during grad school when my research called for it).

Gurman: Apple’s Watch and Health Efforts Need Reboot to Rival New Wearables (Gift Link)

My Amazfit T-Rex 3 Pro 44mm has all the same sensors and features, AI powered by ChatGPT 4.0, 100m diving, support from 6 satellite systems, 3000 nits brightness, titanium build, sapphire glass and 17 DAY battery life at one third the price. Apple needs to play catchup.

Some complaints about the Bip Max compared to the Bip 6

At this rate, I doubt it will last 20 days. It won't. Amazfit's mythical battery life test user is someone in a coma, with all health monitoring and sleep tracking turned off. If that trend continues, you're looking at about 10 days from a full charge, which is actually pretty good for that battery

Rocky - Open-heart surgery

Amazfit certified the T-Rex 3 Pro for diving. This is not happening in other watches from other brands that have those certifications (I.E: Fenix 8 or Suunto Ocean/Nautic). This is is a very serious thing and should be reviewed/fixed. Diving can be very dangerous with faulty devices.

Amazfit Active 3 Premium smartwatch is official

Probably the most unneccesary release I've seen from Amazfit, alognside the T-Rex Ultra 2. They haven't been able to keep up with the Helio Strap demand, still unable to sell a single replacement band for the Helio Strap, the calories algorithm is still super high, sports like swimming are still lac

Found a Pixel Watch 4 demo in London (John Lewis Stratford) : quick impressions

Top stuff, cheers mate. Right now I'm torn between the pw4 45mm and the amazfit t-rex 3 pro. They couldn't possibly be more different. How did it feel navigating around coming from the pw2?

Is the T-Rex 3 Pro that bad?

Actually, this article does a good job of pointing out many of the same concerns users have mentioned here. Amazfit really nails the hardware, but the software still needs work to deliver a smoother overall experience. That said, I don’t have the T-Rex 3 Pro — I use the Balance 2, Active 2, and Heli
