And rightly so, as Zepp (the company behind the Amazfit brand) mostly produces smartwatches that can usually qualified as very strong value-for-money. Models from Amazfit are available for a fraction of what you would pay for similar devices from Garmin and most of the time, the functional differences are minimal.<\/p>\n<p>As both companies offer an extensive range of models, it is quite difficult to decide on a particular one. Hopefully, this review will help to simplify that procedure as well.<\/p>\n<h2 data-toc-id='Uy0QL'>Amazfit T-Rex 3 Overview<\/h2>\n<p>Let&#8217;s start with giving some context: The T-Rex 3 is the latest generation of Amazfit&#8217;s T-Rex series.

The T-Rex 3 stands out primarily for its 1.5&#8243; AMOLED display. With a resolution of 480 x 480 pixels, the display boasts a pixel density of 320 PPI, making it comparable to other smartwatches. It delivers content as sharply as Garmin, Suunto, and Polar watches, while benefiting from a slightly larger diameter.<\/p>\n<h2 data-toc-id='jWCJK'>New and Noteworthy<\/h2>\n<p>Before we dive into the details of the T-Rex 3, here are the watch&#8217;s key new features:<\/p>\n<ul class=\"strong cols-2\">\n<li>1.5&#8243; AMOLED display<\/li>\n<li>Max. 2,000 nits brightness<\/li>\n<li>Stainless steel bezel<\/li>\n<li>Longer battery life<\/li>\n<li>Readiness score<\/li>\n<li>Heart rate variability<\/li>\n<li>177+ sports modes<\/li>\n<li>Offline maps (including contour and ski maps)<\/li>\n<li>Turn-by-turn navigation<\/li>\n<li>GPS privacy settings<\/li>\n<li>AI integration \/ microphone + voice control<\/li>\n<li>26 GB storage<\/li>\n<li>Contactless payment \/ NFC<\/li>\n<li>Suitable for free diving<\/li>\n<\/ul>\n<p>As a reminder, the T-Rex 2 was released in May 2022. Therefore, while all the features mentioned here are new to the T-Rex series, they may not be entirely brand-new. Many of these features were introduced in other products and are now also included in the T-Rex 3.<\/p>\n<h2 data-toc-id='w5sDY'>Unboxing and First Impressions<\/h2>\n<p>For me, unboxing a new watch is still one of the most exciting moments. However, since Amazfit rarely changes the packaging and presentation of its watches, opening the white T-Rex 3 box has been relatively straightforward.<\/p>\n<div id=\"ftt-image-803419645\" style=\"width: 895px\" class=\"wp-caption aligncenter\"><a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-verpackung-2.jpg' data-fancybox data-caption='Amazfit T-Rex 3 in the open box'><img aria-describedby=\"caption-ftt-image-803419645\" loading='lazy' alt='Amazfit T-Rex 3 in the open box' title='Amazfit T-Rex 3 in the open box' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-verpackung-2.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-verpackung-2.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-verpackung-2.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-verpackung-2.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-verpackung-2.jpg 1250w' width='885' height='586' class='ftt-img size-large' \/><\/a><p id=\"caption-ftt-image-803419645\" class=\"wp-caption-text\">Amazfit T-Rex 3 in the open box<\/p><\/div>\n<p>Inside the box, the T-Rex 3 is displayed first, with a protective film over the display to guard against scratches. In my opinion, this isn&#8217;t necessary, as the watch sits securely in its box.<\/p>\n<div id=\"ftt-image-1196748530\" style=\"width: 895px\" class=\"wp-caption aligncenter\"><a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-in-verpackung.jpg' data-fancybox data-caption='Amazfit T-Rex 3 with protective film'><img aria-describedby=\"caption-ftt-image-1196748530\" loading='lazy' alt='Amazfit T-Rex 3 with protective film' title='Amazfit T-Rex 3 with protective film' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-in-verpackung.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-in-verpackung.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-in-verpackung.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-in-verpackung.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-in-verpackung.jpg 1250w' width='885' height='586' class='ftt-img size-large' \/><\/a><p id=\"caption-ftt-image-1196748530\" class=\"wp-caption-text\">Amazfit T-Rex 3 with protective film<\/p><\/div>\n<p>The protective film is the only piece of plastic that needs to be disposed of. Most companies now avoid using cable ties and plastic bags, which is in line with modern sustainability efforts and a positive step forward.<\/p>\n<p>Alongside the watch, there&#8217;s also a small USB charging cradle, adapters for standard straps, and a tiny screwdriver in the box.<\/p>\n<div id=\"ftt-image-1058552269\" style=\"width: 895px\" class=\"wp-caption aligncenter\"><a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zubehoer.jpg' data-fancybox data-caption='Accessories and quick guide'><img aria-describedby=\"caption-ftt-image-1058552269\" loading='lazy' alt='Accessories and quick guide' title='Accessories and quick guide' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zubehoer.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zubehoer.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zubehoer.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zubehoer.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zubehoer.jpg 1250w' width='885' height='586' class='ftt-img size-large' \/><\/a><p id=\"caption-ftt-image-1058552269\" class=\"wp-caption-text\">Accessories and quick guide<\/p><\/div>\n<p>Regarding the USB charging cradle: only the cradle itself is included in the package. Amazfit has opted not to include the cable, which is typically provided with the similar Amazfit Balance charger.<\/p>\n<p>So how does the power get from the adapter to the watch? Via a USB-C cable that plugs into the side port of the charging cradle, which you&#8217;ll need to provide yourself. Given the number of USB cables in most households, this shouldn&#8217;t be an issue.<\/p>\n<p>The small magnet that is supposed to hold the charging cradle in place during charging could be a bit stronger. It tends to slip more than the Balance charger, likely due to the rigid band of the T-Rex 3 that angles away from the watch case at around 60 degrees.<\/p>\n<p>If you want to swap the strap, you&#8217;ll need to attach the included adapters first. After that, you can use standard 22 mm bands with spring bars.<\/p>\n<p>The watch itself stands out with its 1.5&#8243; display and octagonal-round bezel. Octagonal-round doesn&#8217;t make sense? Actually, it does. The outer shape of the bezel is octagonal, while the inner form is round to frame the equally round display.<\/p>\n<div id=\"ftt-image-1483836636\" style=\"width: 895px\" class=\"wp-caption aligncenter\"><a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-1.jpg' data-fancybox data-caption='Octagonal-round bezel of the T-Rex 3'><img aria-describedby=\"caption-ftt-image-1483836636\" loading='lazy' alt='Octagonal-round bezel of the T-Rex 3' title='Octagonal-round bezel of the T-Rex 3' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-1.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-1.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-1.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-1.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-1.jpg 1250w' width='885' height='586' class='ftt-img size-large' \/><\/a><p id=\"caption-ftt-image-1483836636\" class=\"wp-caption-text\">Octagonal-round bezel of the T-Rex 3<\/p><\/div>\n<p>The stainless steel bezel gives it a more premium look than the T-Rex 2. The build quality is high as usual, with no reason for criticism.<\/p>\n<p>The slightly higher weight of the T-Rex 3 is noticeable, especially when switching from the Polar Vantage V3, which I had been wearing for the past few weeks. There\u2019s no question that the target audiences of both watches differ, and like most outdoor watches, the design and weight of the T-Rex 3 are more prominent. While it was noticeable at first, I can confirm that it isn\u2019t distracting at all, even during movement-intensive activities.<\/p>\n<div id=\"ftt-image-156366834\" style=\"width: 895px\" class=\"wp-caption aligncenter\"><a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-2.jpg' data-fancybox data-caption='Visually prominent appearance'><img aria-describedby=\"caption-ftt-image-156366834\" loading='lazy' alt='Visually prominent appearance' title='Visually prominent appearance' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-2.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-2.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-2.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-2.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-profil-2.jpg 1250w' width='885' height='586' class='ftt-img size-large' \/><\/a><p id=\"caption-ftt-image-156366834\" class=\"wp-caption-text\">Visually prominent appearance<\/p><\/div>\n<p>In addition to its weight, the T-Rex 3 also stands out visually.

retains the settings, watch face selection, and app store for connected watches.<\/p>\n<p>The app store still lacks truly standout options. While the selection is growing, nothing has really caught my attention yet.<\/p>\n<p>The watch face selection, however, offers numerous free and now also paid watch faces.<\/p>\n<h3 data-toc-id='x2mfe'>Features adressing everyday life<\/h3>\n<p>Each model in Amazfit&#8217;s portfolio targets a specific user group. Despite these differences, Amazfit smartwatches are generally quite similar, offering a wide range of features adressing everyday life. This holds true for the T-Rex 3, much like the Amazfit Balance.<\/p>\n<h4 data-toc-id='hnEyp'>Voice Control and Zepp Flow<\/h4>\n<p>Not entirely new, but new to the T-Rex series, is the integration of Zepp Flow, which allows for voice control of the watch. Thanks to generative AI, this feature works without predefined keywords, enabling commands in natural language.<\/p>\n<div id=\"ftt-image-1715765588\" style=\"width: 895px\" class=\"wp-caption aligncenter\"><a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zepp-flow.jpg' data-fancybox data-caption='Zepp Flow &#8211; Textual response to spoken question'><img aria-describedby=\"caption-ftt-image-1715765588\" loading='lazy' alt='Zepp Flow &#8211; Textual response to spoken question' title='Zepp Flow &#8211; Textual response to spoken question' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zepp-flow.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zepp-flow.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zepp-flow.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zepp-flow.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-zepp-flow.jpg 1250w' width='885' height='586' class='ftt-img size-large' \/><\/a><p id=\"caption-ftt-image-1715765588\" class=\"wp-caption-text\">Zepp Flow &#8211; Textual response to spoken question<\/p><\/div>\n<p>In my experience, this works remarkably well. The cool part is that not only can you control watch functions, but also ask general questions (e.g., &#8220;How many bridge days are there in April 2025?&#8221;) and get answers directly on the watch.<\/p>\n<p>However, there are two minor limitations:<\/p>\n<ul>\n<li>For more complex voice commands, a paired smartphone needs to be nearby. A limited number of commands (e.g., Start + Workout Name, Open Music) work in Chinese, English, German, and Spanish without smartphone assistance.<\/li>\n<li>Without paired headphones, responses are shown only in text form as the T-Rex 3 lacks a speaker.<\/li>\n<\/ul>\n<p>Ultimately, it is up to each user to decide when and where to use Zepp Flow. For instance, I&#8217;d find it difficult to speak to my watch in a public setting like on public transportation. Nonetheless, it is a feature with great potential that can be further explored over time.<\/p>\n<h4 data-toc-id='lMHOs'>Contactless Payment<\/h4>\n<p>Also new to the T-Rex line is contactless payment via NFC, which Amazfit calls Zepp Pay. Amazfit has taken two approaches here:<\/p>\n<ul>\n<li><strong>Direct integration<\/strong>\n<p>For direct integration, Amazfit faces the same challenges as many other companies: the number of banks is limited, with major banks not yet supported. Currently, Zepp Pay only supports Mastercard, so Visa or debit cards are not supported.<\/li>\n<li><strong>Integration via Curve<\/strong>\n<p>A simpler option, independent of one&#8217;s primary bank, is to link through Curve&#8217;s virtual credit card, which is fully compatible with Amazfit. Transactions are charged to the cards and accounts linked in the Curve app.<\/li>\n<\/ul>\n<h4 data-toc-id='c3lZj'>Music: Storage and Playback<\/h4>\n<p>Amazfit has offered the ability to store and play MP3 files for quite some time. This feature is also available on the T-Rex 3.<\/p>\n<p>Unfortunately and in my opinion, this feature continues to be somewhat underused for several reasons:<\/p>\n<ul>\n<li><strong>Lack of support for streaming services<\/strong>\n<p>In an age where streaming services provide the main access to music, I sorely miss support for popular services like Spotify, Amazon Prime Music, or YouTube Music.<\/li>\n<li><strong>Complicated Data Transfer<\/strong>\n<p>This leaves users with no choice but to transfer the music as MP3 files first to the smartphone and then to the watch via the Zepp App. Setting up a private Wi-Fi connection between the watch and the app is tricky, as the smartphone repeatedly chooses the &#8220;better&#8221; Wi-Fi network with internet access, ending the MP3 upload.<\/p>\n<p>Only disabling the automatic connection to the home network achieves the desired result.<\/li>\n<li><strong>Lack of Organization Features<\/strong>\n<p>Once the music is on the watch, there are no options for organizing the content. Neither directories nor playlists can be created. The two predefined playlists, &#8220;Favorites&#8221; and &#8220;Jogging Music,&#8221; show that the functionality is available in principle but is very limited in its use through the watch and app.<\/p>\n<div id=\"ftt-image-1122456309\" style=\"width: 895px\" class=\"wp-caption aligncenter\"><a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-musik-wiedergabelisten.jpg' data-fancybox data-caption='Music on the T-Rex 3: Essentially only two playlists'><img aria-describedby=\"caption-ftt-image-1122456309\" loading='lazy' alt='Music on the T-Rex 3: Essentially only two playlists' title='Music on the T-Rex 3: Essentially only two playlists' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-musik-wiedergabelisten.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-musik-wiedergabelisten.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-musik-wiedergabelisten.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-musik-wiedergabelisten.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-musik-wiedergabelisten.jpg 1250w' width='885' height='586' class='ftt-img size-large' \/><\/a><p id=\"caption-ftt-image-1122456309\" class=\"wp-caption-text\">Music on the T-Rex 3: Essentially only two playlists<\/p><\/div>\n<\/li>\n<\/ul>\n<p>This feature could be greatly improved if the app displayed the content on the watch and allowed users to create folders and playlists directly within the app.<\/p>\n<p>As it stands, the functionality feels like a &#8216;halfway solution.&#8217; However, the fact that handling MP3 files could be enhanced with just an app update offers hope.<\/p>\n<h4 data-toc-id='tQJmm'>Night Mode in Red, Orange or Green<\/h4>\n<p>Amazfit seems to have taken a cue from the competition, equipping the T-Rex 3 with a night mode that tints the display in red, orange or green hues.

HRV analysis helps to better understand how well the body recovers from physical exertion or psychological stress.

Rather than focusing solely on steps or calories, PAI calculates the heart rate load during various activities and derives a score from it. The higher and longer the effort, the more points you get. The goal is to consistently achieve a PAI score of 100 or higher to reduce the risk of cardiovascular diseases in the long term.<\/p>\n<p>The first points are easy to earn. The higher the score, the harder it becomes to reach high points, which helps keep motivation high.

The T-Rex 3 supports not only dual-band GPS but also GLONASS, Galileo, BeiDou, and QZSS. This is an important feature, as accurate location tracking becomes crucial when venturing off familiar paths.<\/p>\n<p>While there are no mountains, canyons, or other challenging conditions in the suburban areas around Berlin, I tested the watch on familiar routes, both with and without tree cover, through areas with terraced houses and narrow streets to see how well it performed.<\/p>\n<p>What stood out was how effortlessly the T-Rex 3 handled these conditions. There was no reason to complain about its performance, and even the short section through the forest was navigated without issue.<\/p>\n<a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-01.jpg' data-fancybox data-caption='Amazfit T-Rex 3 - Accuracy of location tracking'><img loading='lazy' alt='Amazfit T-Rex 3 - Accuracy of location tracking' title='Amazfit T-Rex 3 - Accuracy of location tracking' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-01.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-01.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-01.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-01.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-01.jpg 1250w' width='885' height='443' class='ftt-img size-large' \/><\/a>\n<p>From a high vantage point, it becomes clear that the GNSS chip and antenna design of the T-Rex 3 do their job seamlessly.<\/p>\n<a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-02.jpg' data-fancybox data-caption='Amazfit T-Rex 3 - Accuracy of location tracking'><img loading='lazy' alt='Amazfit T-Rex 3 - Accuracy of location tracking' title='Amazfit T-Rex 3 - Accuracy of location tracking' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-02.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-02.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-02.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-02.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-02.jpg 1250w' width='885' height='443' class='ftt-img size-large' \/><\/a>\n<a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-03.jpg' data-fancybox data-caption='Amazfit T-Rex 3 - Accuracy of location tracking'><img loading='lazy' alt='Amazfit T-Rex 3 - Accuracy of location tracking' title='Amazfit T-Rex 3 - Accuracy of location tracking' data-mw='885' src='\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-03.jpg' sizes=\"auto, (max-width: 295px) 295px,\n(max-width: 450px) 450px,\n885px\" srcset='\/media\/295\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-03.jpg 295w,\/media\/450\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-03.jpg 450w,\/media\/885\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-03.jpg 885w,\/media\/1250\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-maps-03.jpg 1250w' width='885' height='443' class='ftt-img size-large' \/><\/a>\n<p>Only when looking closely do you see some deviations that both Amazfit models share.

Since the Polar H10 remains a stable measuring instrument, I excluded the initial anomalies for further analysis.<\/p>\n<a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-hr-04.svg' data-fancybox data-caption='Amazfit T-Rex 3 - Accuracy of heart rate measurement'><img loading='lazy' alt='Amazfit T-Rex 3 - Accuracy of heart rate measurement' title='Amazfit T-Rex 3 - Accuracy of heart rate measurement' src='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-hr-04.svg' width='' height='' class='ftt-img size-large' \/><\/a>\n<p>The difference chart highlights the solid performance of the T-Rex 3, although it falls behind during intervals and doesn&#8217;t always capture rapid heart rate spikes accurately.<\/p>\n<div class=\"ftt-grid cols-3\">\n<a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-r2-01.svg' data-fancybox data-caption='Amazfit T-Rex 3 - Accuracy of heart rate measurement'><img loading='lazy' alt='Amazfit T-Rex 3 - Accuracy of heart rate measurement' title='Amazfit T-Rex 3 - Accuracy of heart rate measurement' src='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-r2-01.svg' width='' height='' class='ftt-img size-large' \/><\/a>\n<a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-r2-02.svg' data-fancybox data-caption='Amazfit T-Rex 3 - Accuracy of heart rate measurement'><img loading='lazy' alt='Amazfit T-Rex 3 - Accuracy of heart rate measurement' title='Amazfit T-Rex 3 - Accuracy of heart rate measurement' src='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-r2-02.svg' width='' height='' class='ftt-img size-large' \/><\/a>\n<a href='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-r2-03.svg' data-fancybox data-caption='Amazfit T-Rex 3 - Accuracy of heart rate measurement'><img loading='lazy' alt='Amazfit T-Rex 3 - Accuracy of heart rate measurement' title='Amazfit T-Rex 3 - Accuracy of heart rate measurement' src='\/wp-content\/img\/test\/amazfit-t-rex-3\/amazfit-trex-3-r2-03.svg' width='' height='' class='ftt-img size-large' \/><\/a>\n<\/div>\n<p>This is reflected in the coefficient of determination (r\u00b2), which indicates how well the values from one or the other sport watch matches the heart rate chest strap, which serves as the reference here.<\/p>\n<p>The T-Rex 3 can&#8217;t quite top the comparison and has to let the Coros Pace 3 take the lead. However, it still performs better than the Amazfit Cheetah Pro, which was even less accurate in tracking heart rate during the intervals.<\/p>\n<p>With fewer pace changes, the T-Rex 3 consistently provided reliable and comparable values. During rapid changes in heart rate, it faces the same challenges as many competitors and therefore doesn&#8217;t stand out either positively or negatively.<\/p>\n<h2 data-toc-id='A2PyL'>Battery Life<\/h2>\n<p>On paper, the T-Rex 3 stands out as a true battery life champion. However, confirming or disproving this through user testing is still challenging for me, even after nearly 10 years of testing sports watches.<\/p>\n<p>Company-provided specifications are typically based on controlled environments, so they serve as a general indication rather than an absolute benchmark for real-world usage. Even small changes, such as additional screen activations or adjusting the brightness, can cause these numbers to vary.<\/p>\n<p>As mentioned, the T-Rex 3 impresses on paper, and the great news is that it performs just as well in everyday use. I managed to get through the first three weeks without a charge, although my sports activity was minimal. It was only when the battery dropped to 8% that I needed to recharge.<\/p>\n<p>In the following weeks, the T-Rex 3 had to record activities more frequently. This not only draws more power due to the active GNSS, but the PPG sensor also works at a second-by-second rate.<\/p>\n<p>What does this mean in the end? The battery life specs seem plausible, although I cannot fully validated them due to varying usage. Is this important? No, because the T-Rex 3 offers an impressive battery life regardless and is quickly recharged for the next use.<\/p>\n<section data-template=\"verdict-new\">\n    <h2 class=\"ftt-verdict\" data-toc-id='jAWfq'>Amazfit T-Rex 3 - Verdict<\/h2>\n    <div class=\"ftt-verdict-grid\">\n        <div class=\"ftt-verdict-stars\">\n                            <div class=\"ftt-verdict-score\" title=\"Score: 93%\">\n                    <div style=\"width: calc(var(--rating-star-width) * 93 \/ 100 + 10px)\">\n                        <img decoding=\"async\" src=\"\/wp-content\/plugins\/ftt-verdict\/img\/stars-solid.svg\" alt=\"Score: 93%\">\n                    <\/div>\n                    <div style=\"padding-top: 4px\">Score: 93%<\/div>\n                <\/div>\n                    <\/div>\n        <div class=\"ftt-verdict-procons ftt-grid cols-1\">\n                            <div>\n                    <strong>Pros<\/strong>\n                    <ul>\n                                                    <li>Great 1.5&quot;

Its impressive value-for-money ratio stands out: it offers a wide range of fitness metrics, including Readiness Score, PAI, and HRV analysis, supporting an active and health-focused lifestyle. Outdoor enthusiasts will especially appreciate the offline maps and GNSS support, which provide reliable navigation in various terrains.<\/p>\n<p>Another standout feature is the battery life; even with intensive use, it lasts exceptionally long, making it an attractive option for frequent users and adventurers. The solid build quality, excellent 1.5&#8243; AMOLED display, and intuitive app complete the overall package.<\/p>\n<p>While the T-Rex 3 may not match the Fenix 8 in app variety, advanced mapping features, music functionality, or premium material quality, it certainly holds its own as a competitor. For those unwilling to pay three to four times the price, the T-Rex 3 stands out as an excellent alternative.\n            <\/section>\n        <\/div>\n        <aside class=\"ftt-reader-power\">\n            <div>ONE MORE THING...<\/div>\n            <span>\n                <p>Can you imagine that this is a privately-run website?
