Garmin Venu 4 45mm Smartwatch Review

The Garmin Venu 4 (45mm) is the company’s latest to bridge the gap between a sleek, everyday smartwatch and a powerful, dedicated multisport fitness tracker. Building significantly on the Venu 3, the Venu 4 introduces a more premium metalized design and brings over some of Garmin’s most advanced training features previously reserved for its high-end Forerunner and Fenix lines and I also feel it is taking on WHOOP with some of its features on board which is fine, WHOOP has no display and the watch does so it is a matter of wanting less time on your phone here which I do and have been doing getting metrics on the go by looking at your watch.

The 45mm Venu 4 represents a significant upgrade in build quality, moving to a full metal case that feels noticeably more premium and robust than its predecessors. The watch is stylish enough to look at home in an office setting but durable enough for the trail. It is a familiar design like many watches out there but you can up the style with different bands on offer which are nice like the leather bands.

The 1.4-inch AMOLED display is bright, vibrant, and highly responsive, offering excellent visibility even in direct sunlight. For me after using the watch for some weeks I found this display and it stands out and you can of course customize it even more with faces and make it stand out more.

A new hardware addition is the built-in LED flashlight (with white and red light modes), a feature trickled down from Garmin’s high-end watches, which is surprisingly useful for visibility during night runs or finding something in the dark like keys for trying to get into your house for example or just general looking for things in the dark.

This is where the Venu 4 truly excels, incorporating professional-grade metrics into a lifestyle watch:

  • Training Readiness and Status: Borrowed from the Forerunner series, you now get a morning score based on sleep quality, recovery, HRV, and acute load, helping you determine if you should push hard or take a rest day. Training Status gives you deeper insight into the effectiveness of your overall regimen.
  • Dual-Frequency GPS: The inclusion of Multi-Band (Dual-Frequency) GNSS is a major technical upgrade. This provides superior positional accuracy, especially in challenging environments like dense cities or canyons, making it a reliable tool for runners and outdoor athletes.
  • Lifestyle Logging: A new wellness feature allows you to manually log behaviors like caffeine or alcohol intake directly on the watch. The Garmin Connect app then correlates these entries with changes in key metrics like sleep, stress, and HRV, offering genuinely useful insights into how your daily habits impact your well-being. For me logging things daily is annoying however tried it out here with a general task every day it will pormpt you every day which is not bad for those wanting to use such a feature.
  • Sleep Metrics: The watch offers comprehensive sleep coaching, tracking naps, and introducing Sleep Alignment (how well your sleep pattern matches your circadian rhythm) and Sleep Consistency again wasted on me never used such.
  • Over 80 Sports Apps: The Venu 4 covers virtually every activity, including new features like Mixed Session profiles for tracking multiple activities in one workout (e.g., a triathlon or Hyrox session).

The 45mm Venu 4 offers up to 12 days of battery life in standard smartwatch mode, which is a colossal advantage over competitors like the Apple Watch or Samsung Galaxy Watch which I have both of and can confirm in the real world this is the best watch for battery end of story I own right now.

Always-On Display (AOD): If you use the always-on display, the battery life drops to about 4-5 days, which is still competitive.

GPS Use: Even with the high-accuracy Multi-Band GPS active, the watch can last up to 19 hours, making it excellent for long hikes or marathon training mostly used with ealks for me as out with an injury and still am confined to an extent.

While the Venu 4 is a powerful all-rounder, it has a couple of minor trade-offs:

It lacks the deep, seamless integration and third-party app ecosystem of watches running Apple’s or Google’s operating systems. The voice assistant functionality relies on your paired phone and can feel a bit clunky. I am use to having full rich notifications but this is not the case here with no images in emails such as my cameras etc not a huge deal but miss it.

Unlike some competitors, there is no option for LTE connectivity, meaning you must have your phone nearby for full connectivity and calls however I think most are in this same situation and use the watch and phone for me it has always been the case.

It sits at a higher price point than its predecessor, reflecting the addition of the premium materials and advanced training features and price can be a factor for some people with the feature set, Garmin has a loyal following like Apple and Samsung.

The Garmin Venu 4 45mm which is the model I tested is an exceptional choice for the user who wants a watch that transitions effortlessly between the gym, the trail, and the boardroom. It successfully blends an attractive, premium design with Garmin’s leading-edge fitness and recovery data. If you prioritize multi-day battery life, highly accurate GPS, and deep insights into your fitness and recovery metrics like WHOOP does over the smart communication features of an Apple or Galaxy Watch, the Venu 4 is easily one of the best watches on the market right now if you are not fussy over some small caveats.

What’s new

Health

 

    • Health status: See whether health metrics like heart rate, HRV, respiration, skin temperature1 and Pulse Ox2 while sleeping are trending away from their usual range. These changes could indicate added stress to the body and could be related to physical activity, potential illness and more. This feature is currently available in beta3 on the watch and in Garmin Connect.
  • Lifestyle logging: Log custom or preset behaviours – like caffeine and alcohol consumption – and view reports on how those lifestyle choices impact sleep, stress and HRV in the Garmin Connect app.
  • Advanced sleep metrics: Sleep alignment provides even more personalised sleep guidance by keeping track of how aligned the body is to its inner sleep cycle using circadian rhythm. Sleep consistency provides a look at the average bedtime over the past seven days.

Fitness

The new Garmin Fitness Coach provides personalised workouts for over 25 different fitness activities – from walking and indoor cycling to rowing, HIIT and more. These heart rate and duration-based workouts will adjust daily based on activity history, sleep and recovery. Users can set up a Garmin Fitness Coach plan to receive tailored workouts and track their progress in the Garmin Connect app. If users don’t set up a plan, they will still get daily suggested workouts for different fitness activities. For those doing several activities in one workout, the mixed session activity profile tracks multiple activities in one session rather than saving separate activities. 

Accessibility

 

  • Spoken watch face: Hear time of day, health data and more spoken directly from the watch and receive alerts at the top of every hour.

WHOOP 5.0 MG First Look

Over the last few months I have been testing out the WHOOP 4.0 and about to drop a review on that soon which comes perfectly timed to test out the new WHOOP 5.0 MG and after using the WHOOP 4.0 I can say it has changed me in several ways including habits which I find a good thing and not only that I did wear this to bed for test duration something I never done even with smartwatches and still do not.

Recently launched the new WHOOP line of products ups the game again and I look forward to getting more in depth insights to my health even with WHOOP 4.o my doctor was impressed with what the device offered.

I have noticed myself more and more people using WHOOP devices some with another wearable device and some not, for me I always have a smartwatch on which is good to compare data and see who offers the most accuracy and having many watches to test against WHOOP and other devices it is handy to have this available.

With ECG hardware onboard, WHOOP MG unlocks features like Heart Screener when paired with compatible bands. The device also maintains 24/7 tracking capabilities—including heart rate, strain, sleep, skin temperature, and more.

WHOOP MG features a compact yet powerful design that’s 7% smaller than WHOOP 4.0, with a matte black finish and brushed metal detailing. It weighs slightly more than WHOOP 5.0 (~27.3 g), due to the conductive clasp required for ECG signal acquisition.

 

Features

  • EVERYTHING YOU NEED IS INCLUDED: Your WHOOP purchase includes a 12-month WHOOP Life membership, a WHOOP MG device, a SuperKnit Luxe band, and a waterproof* Wireless PowerPack.
  • CONTINUOUS MONITORING: WHOOP continuously monitors your physiological data, including sleep, stress, VO2 max, blood pressure*, and heart health metrics—providing 24/7 insights to optimize fitness, recovery, and overall health.
  • ADVANCED INSIGHTS: WHOOP Life seamlessly integrates total-health screening into your routine
  • ON-DEMAND ECG READINGS: With electrocardiogram readings, Heart Screener detects potential signs of AFib to help you stay informed about your heart health.*
  • FIRST-OF-ITS-KIND BLOOD PRESSURE TECHNOLOGY: Get blood pressure insights*, including systolic and diastolic ranges, and learn about how blood pressure affects your well-being and performance.
