In this Amazfit Active 3 vs Garmin Forerunner 165 comparison, the right watch comes down to whether you want navigation and long battery or structured training guidance.
The Forerunner 55 scores 9.5 on our scale and the Active 3 scores 7.6. That gap reflects how each watch fits a runner's daily needs rather than screen quality alone.
The Garmin leans on training features; the Amazfit leans on display, maps and time between charges.
Both are GPS running watches. One costs more and one costs less, but neither wins on every point.
Here's how to choose.
Amazfit Active 3 vs Garmin Forerunner 165: the quick verdict
The Garmin Forerunner 55 is the better watch for most runners, and the Amazfit Active 3 is the better pick when maps and battery life top your list. That's the short answer to the Amazfit Active 3 vs Garmin Forerunner 165 question.
The Forerunner 55 gives you daily suggested workouts that adapt to your training history, fitness level and recovery time. PacePro adds GPS-based pacing for a selected course or distance, and race predictions estimate your finish time.
That's a lot of coaching built into a light 37 g watch.
The Active 3 gives you a 1.32-inch AMOLED display with sapphire glass and a stainless steel frame. Amazfit includes free offline maps with turn-by-turn directions and automatic rerouting, all without your phone.
Battery runs up to 12 days in typical use.
Our score weighs specs, features and how well each watch fits what a runner shopping in this category wants. On that basis the Forerunner 55 is the safer default and the Active 3 is the specialist.

The two watches side by side
These watches differ most in display type, battery life, map support and training software. The table below puts the main specs next to each other.
| Product | Best for | Display | Battery | Maps | Our score |
|---|---|---|---|---|---|
| Amazfit Active 3 | battery and maps | 1.32 in AMOLED, sapphire glass | 12 days typical, 24 hours GPS | Free offline maps | 7.6 |
| Garmin Forerunner 55 | simple run tracking | Sunlight-visible MIP | 2 weeks smartwatch, 20 hours GPS | 9.5 |
The Forerunner 55 uses a sunlight-visible, transflective memory-in-pixel display. That type stays readable in bright sun and sips power, which helps its up-to-2-week smartwatch battery and up-to-20-hour GPS mode.
It has five buttons and a 37 g body.
The Active 3 uses a 1.32-inch AMOLED screen with sapphire glass over a stainless steel frame. Amazfit says the screen reaches 3,000 nits, so it stays clear in direct sunlight.
It has four button controls plus the touchscreen.
Both track heart rate at the wrist and use GPS to measure distance and pace. Neither is a medical device.
Both work with iOS and Android phones over Bluetooth.
Battery and charging compared
The Forerunner 55 runs up to 2 weeks in smartwatch mode and up to 20 hours in GPS mode. The Active 3 runs up to 12 days in typical use, 7 days in heavy use, or 24 hours with continuous GPS route tracking.
That makes the Garmin the longer-lasting everyday watch. The Amazfit gives you more continuous GPS time, which helps on long trail runs or hikes where maps matter.
Charging differs too: both ship with a magnetic charging base, and neither includes a USB-C cable.
Display and build compared
The Active 3's AMOLED screen and sapphire glass are its headline features. Sapphire resists scratches, and the stainless steel frame adds a more premium feel for daily wear.
The 1.32-inch size keeps the case compact.
The Forerunner 55's MIP display is less vivid but easier to read in harsh sunlight and kinder to battery. Its 37 g weight makes it one of the lighter running watches in this comparison.
Pick the Garmin if you want a light training tool. Pick the Amazfit if the screen is something you'll look at all day.
Weight, controls and fit compared
The Forerunner 55 weighs 37 g and measures 1.65 by 1.65 by 0.46 inches. That is a small, button-only case built to sit still on the wrist during a run.
All five controls are physical buttons, so you can start, lap and stop without looking down at a touchscreen.
The Active 3 uses a mix of four buttons and touch. It has a touchscreen alongside its button controls, so menus, maps and message replies are handled by tapping or swiping.
The case is listed at 2.82 ounces with a stainless steel frame and a silicone band on a buckle.
The weight difference matters most in the last miles of a long run. The Garmin's lighter body is the easier one to forget you're wearing, while the Amazfit's steel frame and larger screen feel more like a smartwatch on the wrist.
Connectivity and phone support
Both watches pair to iOS and Android phones over Bluetooth. The Forerunner 55 syncs with the Garmin Connect app and pulls watch faces, data fields, apps and widgets from the Connect IQ Store.
That store needs both the Garmin Connect app and the Connect IQ app on a compatible smartphone.
The Active 3 works through the free Zepp app. It adds Bluetooth calling through your phone, voice control through Zepp Flow and speech-to-text replies from the wrist.
Android users get the full messaging feature set; the watch still pairs fine with an iPhone for the basics.
If you want a watch that stays close to your phone's notifications and calls, the Amazfit does more out of the box. If you mainly want workout data syncing cleanly to one app, Garmin Connect covers that well.
Battery life: which watch lasts longer between charges?
The Forerunner 55 wins on everyday battery life, while the Active 3 wins on continuous GPS time. Your training volume decides which number matters more.
The Garmin's up to 2 weeks in smartwatch mode covers most runners' daily wear plus several short runs. Its 20 hours in GPS mode is enough for a marathon and then some.
The Amazfit's 12 days of typical use is still generous. Its 24 hours of continuous GPS tracking edges the Garmin by four hours, which matters for ultra events or long days on trails with maps running.
The spec sheet also splits the Active 3's battery into 12 days typical and 7 days heavy use, so the real figure depends on how much GPS, calls and screen time you add.
If you charge weekly anyway, the gap narrows. If you want to leave the charger at home on a weekend trip, the Garmin's two-week figure is the easier one to trust.
Neither watch uses a proprietary charging cable here; both come with a magnetic charging base. Carry the base, not a spare cable, when you travel.
Maps and navigation: who handles routes better?
The Amazfit Active 3 has offline maps; the Forerunner 55 does not. That's the single biggest functional split between these two watches.
Amazfit includes free downloadable maps with turn-by-turn directions and automatic rerouting. The Active 3 uses six GPS satellite systems to find your position, and you don't need your phone to follow a route.
It also has 4GB of storage for maps and music.
The Forerunner 55 relies on GPS tracking without on-device maps. Its PacePro feature gives GPS-based pace guidance for a selected course or distance, but it isn't compatible with on-device courses.
So you get pacing help, not a map on your wrist. Its memory is listed at 32 MB, which tells you the design is built around tracking and training data rather than storing map tiles.
If you run the same routes and only want pace and distance, the Garmin is enough. If you explore new trails or race unfamiliar courses, the Amazfit's maps are the feature to pay for.
The six-satellite positioning on the Active 3 also helps in tree cover and city streets, where a clear fix takes longer. The Garmin's GPS is built for accurate distance and pace tracking, and PacePro then turns that into guidance on a course you already know.

Training tools: Garmin's software vs Amazfit's coaching
Garmin gives you more structured training help; Amazfit gives you solid plans through the Zepp app. The difference is depth, not whether coaching exists.
The Forerunner 55 builds suggested workouts from your training history, fitness level and recovery time. It also tracks intensity minutes, fitness age and all-day respiration.
Activity profiles cover running, cycling, track run, virtual run, pool swim, Pilates, HIIT and breathwork. Race time predictions and finish time estimates round out the training package.
The Active 3 includes training programs from 5K to marathon with Zepp Coach. It tracks running power, lactate threshold, posture and ground contact to help your run form.
It has over 170 workout modes, including HYROX training.
The Garmin's coaching is more automated and tied to your recovery. The Amazfit's plans are broader in workout variety.
Pick Garmin if you want the watch to tell you what to do next; pick Amazfit if you like a big menu of sports.
What each training system actually gives you
Garmin's daily suggested workouts change based on how hard you've been training and how well you've recovered. That means the watch can push you on a fresh day and ease off after a hard session without you planning anything.
PacePro takes it further on race day by giving GPS-based pacing for a chosen course or distance, and the race predictions give you a realistic finish time to aim at.
Amazfit's Zepp Coach offers structured plans for 5K, 10K, half marathon and full marathon, plus a HYROX training mode among the 170+ workouts. The Active 3 also reports running power, lactate threshold, posture and ground contact.
Those metrics are useful for form work, but they are numbers you interpret rather than a plan that adjusts tomorrow's session for you.
The practical split: Garmin closes the loop from data to next workout, while Amazfit hands you more data and more workout types to choose from. A beginner who wants to be told what to run next will prefer the Garmin.
A runner who likes to pick and mix sports will prefer the Amazfit's 170+ modes.
Everyday use: which watch fits daily wear?
The Active 3 looks and feels more like a daily watch; the Forerunner 55 stays out of the way. Both handle notifications and phone pairing, so the choice is about feel.
The Active 3 has a stainless steel frame and sapphire glass, plus a 1.32-inch AMOLED screen. Amazfit includes Bluetooth calls through your phone and voice control via Zepp Flow.
Android users can send speech-to-text replies from the wrist. A built-in speaker and mic make calls possible without stopping.
It also stores music on 4GB of internal memory, so podcasts and playlists can live on the watch.
The Forerunner 55 is lighter at 37 g with a button-only interface. It syncs with the Garmin Connect app and the Connect IQ Store for free watch faces, data fields, apps and widgets.
It's less flashy but easy to live with.
If you take calls and read messages on the go, the Amazfit does more. If you want a watch you forget you're wearing on a run, the Garmin's lighter body helps.
Health and recovery tracking compared
Both watches track heart rate, sleep and stress; the Amazfit adds blood oxygen and the Garmin adds fitness age and respiration. Neither is a medical device, so treat the numbers as trends rather than diagnoses.
The Active 3's BioTracker monitors heart rate, blood oxygen, stress and sleep. Amazfit's BioCharge score adjusts with your daily workouts and stress levels to suggest when to push harder and when to rest.
The Forerunner 55 tracks wrist heart rate, intensity minutes, fitness age and all-day respiration. It uses those signals to shape its daily suggested workouts.
All-day respiration monitoring and intensity minutes both feed into how the watch reads your day.
The Garmin's health data feeds directly into its training advice. The Amazfit's health data feeds its BioCharge recovery score.
Both give you a picture of how your body is responding; the difference is how each watch turns that into a next step.
If recovery guidance shapes your training, either works. If you want the watch to adjust tomorrow's workout, Garmin's loop is tighter.
Which should you buy?
Buy the Garmin Forerunner 55 if you want dependable run tracking and automated coaching in a light watch. Buy the Amazfit Active 3 if maps, a bright screen and long battery matter more than training software.
Pick the Forerunner 55 for most runners. It's the higher-scored watch here for good reason: daily suggested workouts, PacePro pacing and race predictions cover the basics of structured training.
The two-week smartwatch battery means fewer charging breaks, and 37 g is easy to wear.
Pick the Active 3 if you run trails or races where you need turn-by-turn directions without your phone. The sapphire glass and AMOLED screen also make it the nicer everyday watch.
Its 12-day typical battery and 24-hour GPS mode suit long days out.
Skip the Garmin if offline maps are a must. Skip the Amazfit if you want Garmin's training ecosystem and don't need navigation.
