1. Praise for Battery Life and Durability
One of the most frequently praised aspects of the Suunto 9 Series is its impressive battery efficiency. Reddit users in endurance sports, such as ultrarunning and hiking, frequently discuss the watch's ability to last for extended periods with intelligent battery modes.
User @u/TrailRunner84 in r/UltraRunning praised the battery life, stating:
“I did a 50-mile trail run, and my Suunto 9 was still at 45% after 12 hours of tracking. The endurance mode really helps to avoid battery anxiety compared to my old Garmin.”
Many athletes appreciate how the "FusedTrack" technology optimizes battery use without sacrificing too much accuracy—a feature that seems to stand out among long-distance adventurers.
Another key point of praise is durability. Many users report that the device withstands extreme conditions:
User @u/MountainGoat42 in r/Hiking said:
“I've banged my Suunto 9 against rocks, submerged it multiple times, and it's still functioning perfectly. The sapphire glass really makes a difference.”
This type of rugged resilience is a recurring theme, especially among hikers, mountaineers, and military personnel.
2. Mixed Feelings About GPS Accuracy
While many appreciate its smart tracking features, GPS accuracy is a point of contention among Reddit users. Some report that Suunto's GPS is highly accurate and reliable, while others note occasional drift or inconsistent tracking compared to competitors like Garmin and Coros.
User @u/CyclingGenius in r/running:**
“It’s solid for general tracking and outdoor navigation, but when I compare it against my friend’s Garmin Forerunner, I see slight deviations, especially in wooded areas.”
However, others argue that while the instantaneous accuracy might lag compared to Garmin devices, Suunto 9's algorithms help correct data post-run:
User @u/DataDrivenRunner in r/running:**
“Garmin is more accurate moment-to-moment, but when I sync my Suunto data to Strava, the post-processing makes it nearly identical to Garmin’s baseline.”
This suggests that while Suunto might have some minor shortcomings in real-time GPS tracking, it performs well in post-run analysis.
3. Issues with Software and Syncing
While Suunto gets praise for hardware quality, software performance and syncing tend to be a major complaint on Reddit forums. Many users feel that while Suunto’s hardware is world-class, its software ecosystem lags behind competitors like Garmin Connect and Coros’ platform.
User @u/TechAthlete in r/triathlon:
“Don't expect the Suunto app to be as polished as Garmin Connect. It gets the job done, but it's lacking in UX/UI. Syncing to third-party apps like Strava can also be finicky at times.”
Others complain about workout syncing issues and limited customization:
User @u/NightRun89 in r/Suunto:
“I had issues with my workouts not syncing automatically to Strava. I had to restart the app a few times before it worked. Garmin’s system for this is much smoother.”
That being said, some users appreciate Suunto’s minimalistic, no-frills software:
User @u/MinimalistCoach in r/running:
“If you want insane amounts of data, go for Garmin. If you prefer simplicity, Suunto keeps things clean and to the point.”
This shows that while some users value deep analytics and integration, others favor simplicity and a clutter-free experience.
4. Comparing Suunto 9 to Garmin, Coros, and Polar
Many Reddit threads are filled with discussions comparing the Suunto 9 Series to competitors like Garmin, Coros, and Polar. Users generally agree that:
- Garmin offers better GPS accuracy and a richer software experience
- Coros provides better battery life at a lower price point
- Polar has superior HR tracking and running dynamics
User @u/GarminFanatic in r/watches:
“I moved from Suunto 9 to a Garmin Fenix 6 because I wanted better software and integration with third-party platforms.”
On the flip side, some users stuck with Suunto for its durability and ultra-endurance features:
User @u/MountainHiker99 in r/ultralight:
“I've owned both Suunto and Garmin. If you're into extreme adventures, Suunto's battery-saving tricks are superb. I can go a full weekend trek without worrying about charging.”
5. Final Verdict: Should You Get the Suunto 9?

4. Software and User Interface: "Good Hardware, Bad Software?"
One frequent Reddit complaint about the Suunto 9 Series is the Suunto app and software experience. While the watch hardware is top-notch, many users feel the software lacks the polish of Garmin or Apple.
