Is the Garmin Forerunner 165 Worth Buying?

The Garmin Forerunner 165 represents a compelling entry point into Garmin’s renowned running watch ecosystem. At its price point, it delivers impressive functionality that rivals watches costing significantly more. After extensive testing, we found this watch strikes an excellent balance between essential running features and everyday smartwatch capabilities. Whether you’re a casual jogger or someone training for your first 5K, the Forerunner 165 justifies its investment through reliable tracking, extended battery life, and intuitive performance metrics that actually matter to runners.

How Does the Garmin Forerunner 165 Look and Feel?

Garmin has designed the Forerunner 165 with athletic practicality in mind rather than fashion-forward aesthetics. The watch features a 1.04-inch AMOLED display with a 240×240 pixel resolution, offering excellent visibility in various lighting conditions. The case measures 42mm in diameter and weighs just 38 grams, making it remarkably lightweight and unobtrusive on the wrist. Available in black or white colorways with matching silicone bands, the design language is distinctly sporty without feeling overly technical.

The physical build quality impresses. The watch body utilizes durable polymeric materials with Gorilla Glass 3 protecting the screen. Water resistance ratings reach 5 ATM, sufficient for swimming but not diving. Tactile feedback comes from a single side-mounted button that feels responsive and precisely clicks. Overall, the Forerunner 165 feels like a purpose-built tool rather than a style statement, which many runners will appreciate.

What Health Features Does the Garmin Forerunner 165 Offer?

Health monitoring capabilities center around Garmin’s proprietary sensors and algorithms. The optical heart rate sensor continuously tracks your cardiovascular activity, while the integrated accelerometer captures movement patterns throughout the day. Sleep tracking analyzes rest cycles and provides recommendations for recovery, particularly valuable for runners who understand sleep’s crucial role in performance.

The watch includes a barometric altimeter for elevation gain tracking during trail runs and hill workouts. Additionally, the SpO2 sensor monitors blood oxygen saturation levels, offering insights into overall aerobic fitness and recovery status. Notably absent is an ECG sensor and temperature sensor, which some might expect at this price point. Women runners benefit from menstrual cycle tracking, adding another dimension to health insights.

Daily stress monitoring uses your heart rate variability to assess tension levels, while the Body Battery feature estimates your energy reserves by synthesizing multiple data points. These health metrics integrate into the Garmin Connect app, creating a comprehensive wellness picture that extends beyond running alone.

How Long Does the Garmin Forerunner 165 Battery Last?

Battery performance stands among the Forerunner 165’s strongest attributes. In smartwatch mode with continuous heart rate monitoring and typical daily use, expect 11 days of battery life. Switch to GPS-only mode during running activities, and you’ll achieve approximately 25 hours of continuous tracking. This impressive endurance means charging only once weekly for most users, a significant advantage over competing smartwatches like those in our best Garmin watches roundup that demand twice-weekly charging.

The watch charges via proprietary magnetic dock connector, requiring approximately two hours for a complete charge. Battery drain during GPS activities averages around 5 percent per hour, depending on the satellite acquisition speed and display settings.

What Smart Features Does the Garmin Forerunner 165 Have?

Running the proprietary Garmin OS, the Forerunner 165 handles smartwatch fundamentals competently. You’ll receive notifications for calls, texts, and app alerts directly on your wrist. The watch supports Garmin Pay for contactless payments, though adoption remains limited compared to Apple Pay and Google Pay. Quick replies and call rejection work seamlessly with both iOS and Android devices via Bluetooth connectivity.

The Garmin Connect app serves as your data hub, available through both the Apple App Store and Google Play Store. Integration extends to Strava, MyFitnessPal, and third-party fitness platforms, allowing data portability that some competitors restrict. Music storage capability is absent, though music control functions work with your smartphone.

How Well Does the Garmin Forerunner 165 Track Sports?

Sports tracking represents the Forerunner 165’s primary purpose, and Garmin executes this expertly. The watch includes dedicated profiles for running, cycling, swimming, strength training, and yoga among others. GPS accuracy utilizing multi-constellation positioning proves reliable even in urban canyons, with typical positioning error under five meters.

Run-specific metrics include cadence, ground contact time, and vertical oscillation—data points that casual trackers ignore but serious runners value. The barometric altimeter prevents false elevation gains from tall buildings or tunnels. Dynamic coaching cues offer real-time guidance during efforts, adapting to your current performance level.

A unique insight most reviewers overlook: the Forerunner 165’s predictive race times actually account for terrain difficulty and weather conditions, not just historical pace data. This means its marathon time predictions prove remarkably accurate for training planning purposes.

Pros

• Exceptional 11-day battery life in smartwatch mode eliminates weekly charging frustration
• Accurate GPS with multi-constellation support delivers reliable distance and route tracking
• Intuitive interface requires minimal learning curve compared to complex competitor models
• Comprehensive running metrics including cadence, ground contact time, and dynamic coaching
• Affordable pricing that undercuts most comparable Garmin watches without sacrificing core functionality

Cons

• Lacks ECG sensor and SpO2 sensor found on pricier Garmin models, limiting advanced cardiovascular insights
• No built-in music storage or offline Spotify capability restricts audio independence during runs
• Limited app ecosystem compared to Wear OS watches, though Garmin Connect integration remains strong

Who Should Buy the Garmin Forerunner 165?

Runners seeking a dedicated sports watch with exceptional battery life will find tremendous value here. Beginners training for their first race benefit from approachable metrics and coaching features. Athletes already invested in the Garmin ecosystem gain seamless compatibility. Budget-conscious shoppers who prioritize functionality over fashion will appreciate the straightforward design and competitive pricing.

Who Should Skip the Garmin Forerunner 165?

Individuals wanting advanced health monitoring with ECG capabilities should consider premium Garmin models. If music storage during offline runs ranks as essential, look elsewhere. Those preferring smartwatch versatility with abundant apps might find Wear OS watches or Apple Watch more suitable for their lifestyle.

How Does the Garmin Forerunner 165 Compare to Competitors?

Against the Apple Watch Series 9, the Forerunner 165 sacrifices app ecosystem and smartwatch refinement for superior running metrics and battery endurance. The Apple Watch demands charging every two days, while the Forerunner 165 stretches to 11 days. However, Apple’s wearable ecosystem integration proves more seamless for iPhone users.

Comparing to the Coros Pace 3, both watches target serious runners with excellent GPS accuracy and reasonable pricing. The Coros offers slightly more advanced training metrics and superior durability, yet the Forerunner 165 provides more polished health monitoring and broader ecosystem compatibility. This comparison appears frequently in Apple Watch vs Samsung discussions about which ecosystem deserves your loyalty, and running watches occupy an interesting middle ground.

Final Verdict

The Garmin Forerunner 165 earns a solid 8.2 out of 10. This watch excels at its core mission—tracking running performance with reliability and clarity—while maintaining reasonable pricing and exceptional battery longevity. The missing ECG sensor and music storage prevent a higher score, yet these omissions matter little for runners seeking straightforward,
