Based on 1 year's data from Feb 15, 2026 How it works
the t rex 3 pro seems good and it has calling functions the torch light seems super useful as well, i am so tempted to upgrade from my already excellent t rex ultra
there's the flashlight that's useful in a pinch, i think it has a mic so u can speak into it, then there's also the titanium used over steel and the sapphire glass thats more hardy i am not too sure on the routes yet but yes i think thats the advantage over it too i am currently using the t rex ultra which is still a champ, but fingers are feeling itchy to get the 3 pro
Amazfit trex. I have the trex pro, but the newer 3 and ultra are pretty cool. I think they are all less than 300
I love Amazfit. I have the T-Rex and T-Rex 3, the 3 gets about 14-18 days of battery even with GPS on.
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.
Depending on what features we are talking about, Garmin Venu 3 and Amazfit (Balance, TRex) both are delivering strong battery.
Don't rule out Amazfit. I've been running a trex for 3 years now. They compare favorably to Garmin.
I have the amazfit Trex and I feel like it does everything I’d want. Had it for at least 3 years. Charge it every couple of weeks.
“‘Best’ is kind of impossible without knowing your budget and what you care about most, but here’s the short version for 2025: * **If you mainly want fitness + crazy battery** → look at **Garmin** (Forerunner / Venu / Fénix / Epix depending on your budget and if you want AMOLED or not). Great GPS, stats, and works well with both Android & iOS, but smart features are more basic. * **If you want a “do everything” smartwatch and you’re OK with daily charging** → * On **iOS**: Apple Watch (if your iPhone is recent enough, that’s still the most seamless option). * On **Android**: **Galaxy Watch** or **Pixel Watch** families for the best apps + integration. * **If you want something cheaper but solid for fitness** → Amazfit (T-Rex, Cheetah, etc.) gives good GPS + long battery for the price, with decent app support. Since you have both Android and iOS, I’d start by asking: * Do you care more about **fitness metrics + battery** or **apps + smart features**? * Max budget? Answer that and people here can give you 2–3 very precise models instead of generic “get an Apple Watch” replies.”
Start with running shorts with tights. This is essential for me. I won’t consider running without them. They reduce chafing around the thighs, making the entire run more comfortable. For the top, keep it simple. Any lightweight, quick-dry T-shirt works well. Don't overthink this part. Next comes the shoes. Start with a basic running shoe until you understand your running mechanics, like heel strike, foot placement, and pronation. There’s no need to invest heavily before you figure out what suits your running style. Finally, get a tracker. If you carry your phone while running, a basic fitness band without GPS is more than enough (Samsung Fit 3, Mi Band, Amazfit Bip). If you don’t carry your phone, then go for a proper running watch with dual-band GPS (Coros, Samsung Watch 7/8, Amazfit Balance or T-Rex series). Hydration becomes important only for long runs (anything over 90 minutes). For shorter runs, it’s usually not necessary.
I had an amazfit t rex which did the business for a good few years, worth checking out their models. Upgraded to a one plus 2r and most of the time doesn't feel like an upgrade
