We tested our Amazfit T - Rex 3 for about two months and can attest to its staying power . While admittedly we did not go to extremes with the testing physical process ( we are not professional divers ) , the watch did not hold any scuffs , dough or wear - and - bust harm . Cold February temperature , rainwater or spicy showers did not faze it either .
We also plant it astonishingly comfortable to wear . The Amazfit T - Rex 3 weigh a strong 2.4 oz ( 68.3 grand ) without a strap so is heavier than most of thebest Garmin watch , for example , but it did not weigh our wrist down . The silicone polymer strap were thick yet soft , and they handle to keep our watch steadfastly in station without aggravate the skin . We also liked that they were removable . The Amazfit T - Rex 3 comes with a strap - changing kit , and you may corrupt plenty of unlike straps online if you fancy a change .
That say , we did not really warm to the chunky design of our Amazfit T - Rex 3 . The sentinel is just too big to be tire out well in bed , and unlike most mainstream model , it is only usable in one size . We were not convinced by its too rugged looks , either . While this watch would couple well with miry boots and climb gear , it may collide with more casual clothing . The Amazfit T - Rex 3 is somewhat impractical for 24/7 wearable .
The Amazfit T-Rex 3 offers excellent value for money.
Amazfit T-Rex 3: Display
The 1.5 - inch AMOLED display definitely warrants a credit . It is sunnily lustrous and colorful , and its large size makes it easy to read . The display can also be customized with one C of watch faces to suit your modality , style and trailing preferences . This is a major bonus point for us — we like wearables to reflect the drug user ’s goals and personality .
More significantly , the display showed sound visibility in shining or low - light condition , even though the pictures of our T - Rex 3 may not inevitably show that ( the flash give rise excessive glare so we opt for raw lightness instead . ) We also did not see lags or any other problem with touchscreen reactivity .
What we were slimly surprised by was its confusing navigation . It is slimly less intuitive and user - favorable than other Amazfit sentinel we test , even though all of these devices share largely the same layout . However , find dissimilar features and setting got easier the more we used the watch .
We tested the Amazfit T-Rex 3 smartwatch for two months.

grant to the steel , the Amazfit T - Rex 3 lasts up to 13 days in " heavy use " , up to 27 days in " typical use " and up to 180 hours with " continuous out-of-door GPS natural action " — and that band true . Our typical use would include continuous heart tracking , hour - foresighted workouts on most days of the week and kip cross almost every night , and under these conditions , our watch lasted on average two to three week on a unmarried bursting charge . We did not have the chance to test if it survive 180 hour with GPS on , but battery utilisation in that mode seemed uniform with the claim .
The tracking in the T - Rex 3 vigil was mostly accurate , especially with sleep , dance step count and certain sportswoman - specific system of measurement ( stroke rate in indoor row , for deterrent example . ) GPS navigation also seemed to influence well for us , locating our position with a good degree of accuracy and in a reasonable sentence . However , we only had the opportunity to test the watch during walk in towns and other populated area — we ca n’t vouch for the accuracy of its GPS in any other environments .
The Amazfit T - Rex performed well in our heart rate mental testing , too . We did an hour - long exercising wear out both the watch and aPolar H9chest - shoulder strap substance rate monitor , then equate the measure between the twist . The heart charge per unit was comparatively accurate during quietus and moderate activity , but it became slightly less honest with high - volume practice . However , these results are consistent with the heart rate measurements give by more premium fittingness tracker .
The only performance - touch on issue we know was unreliable drift tracking during forcefulness - based workouts . The Amazfit T - Rex 3 promises to " intelligently count your reps , sets and rest metre " and evaluate your movement based on stability , calendar method of birth control and other metric function . In our experience , this feature film omit the bell ringer on all accounts , with wildly inaccurate appraisal and inconsistent performance during almost every resistance workout .
