I have a Huawei GT3 and a Galaxy S21FE, and it works perfectly. You download Huawei Health from the Samsung app store. And it works very well. I mainly use it for swimming, but I do miss the kick function.
Ok so I have a GT3 and I have been looking for a reason to upgrade, Like I upgraded from GT2 to be able to connect an external Polar HR strap. What did you lack in GT4 that you have in GT6?
I have in the past but now I use a dedicated bike computer. There are some well within your budget that have maps and would be way better than trying to navigate using a small watch screen. There are a couple of Magene computers you can get on AliExpress that are highly rated for the $$. If you are really committed to having a watch, there are a lot of Garmin competitors that would work. I'm thinking Amazfit Trex (or one of the many other watches in the range), Huawei GT etc. off the top of my head.
I’m on the fence about getting another Amazfit and am considering the new Active 3. I bought a T-Rex Pro in late 2023 for $100 on sale, and the battery died about 2½ years later. Great watch for my use, but now it is 3xs the price. Before that, another Amazfit that only lasted 14 months. I preferred using an alternative app which is more accurate over Zepp, which still feels stagnant and gimmicky. I don't need a smart watch app to help me get my Chakras in order. The best-built and best-looking watch I’ve owned was a Huawei GT, solid, premium, and long-lasting, but software restrictions in the U.S. make it a hassle to use. My Garmin Fenix (bought on sale for $450) lasted five years and had far better software, especially with the online mapping and activity management. I’ve also looked at the Kospet Tank M4, but it’s huge and looks like a brick and a toy on most wrists. Amazfit prices seem to have doubled, and newer models look more sealed and harder to repair. I’m going to try replacing the battery in my T-Rex Pro, which I loved, but at roughly $50 -$100+ per year of lifespan, these watches are built with planned obsolescence in mind. If Amazfit prices keep climbing and they keep pushing gimmicky subscriptions, I’ll probably just go back to Garmin.
If you are concerned about battery life, we recommend a smartwatch from a Chinese manufacturer. If you care about your health, the Huawei GT series is the one for you.I can recommend it. The best one for everyday use is the amazfit. I own the GTR3pro and am very happy with it.
