The main reason I decided to switch from Pixel Watch to Garmin Venu 3 was the battery life issue. While I could certainly feel the good compatibility I expected with my Android Pixel 7 Pro, the practical challenges were too significant.
🔋 Battery Duration
Wearing from 7 AM, battery drops below 20% by 10 PM, making sleep data collection impossible
💤 Lack of Sleep Analysis
Need to remove at night for charging, unable to understand sleep quality and patterns
⚡ High Charging Frequency
Daily charging required, unusable on days when charging is forgotten
🏃♂️ Insufficient Fitness Functions
Basic step counting possible, but limitations for serious exercise recording
As an IT engineer living an irregular lifestyle, I had a strong desire to objectively understand sleep quality. However, with the Pixel Watch, I couldn’t collect sleep data due to charging requirements, missing a fundamental part of health management.
After actually using it for one month, the Garmin Venu 3 delivered performance that exceeded expectations. The progress in health management was particularly remarkable, providing specific improvement suggestions for health issues unique to the IT engineer profession.
The biggest change is battery duration. With normal use lasting 4-5 days, 24-hour continuous measurement including sleep data became possible.
🔋 Actual Battery Duration
4 days and 18 hours with normal use (notifications ON, continuous heart rate monitoring, GPS twice weekly)
⚡ Charging Time
Approximately 1 hour 30 minutes from 0% to 100%, fast charging supported
💤 24-Hour Wearing Achieved
Continuous measurement of sleep data, heart rate, and stress levels without worrying about charging
Sleep data that couldn’t be obtained with Pixel Watch is analyzed in detail with Venu 3. Being able to objectively view the irregular lifestyle patterns of IT engineers was particularly valuable.
📊 Sleep Score
Average 75 points (good), detailed display of deep sleep, light sleep, and REM sleep ratios
⚡ Body Battery Function
Morning energy levels quantified, utilized for adjusting daily activity levels
📈 Sleep Trend Analysis
Discovering lifestyle improvement points from weekly and monthly sleep patterns
💡 Specific Improvement Suggestions
Regularizing bedtime, optimizing caffeine intake timing, etc.
Looking at one month of data, an irregular pattern was visualized with weekday sleep around 6 hours being short and weekend sleep extending to 7-8 hours. From this insight, I implemented a 30-minute earlier bedtime on weekdays, resulting in an average 15% improvement in Body Battery score.
The fitness functions, which are Garmin’s original strength, achieved the expected high accuracy.
🎯 GPS Accuracy
Running course recording very accurate, distance measurement error less than 1%
💓 Heart Rate Zone Management
Exercise intensity optimization with 5 heart rate zones, enabling efficient training
📈 VO2 Max Measurement
Maximum oxygen uptake of 44 (above age average), understanding objective fitness level
🏃♂️ Exercise Suggestion Function
Sedentary alerts, hourly light exercise suggestions help resolve lack of exercise
Regarding integration with Android Pixel 7 Pro, while there’s a slight gap compared to Pixel Watch, it’s sufficiently satisfactory for practical purposes.
📱 Notification Function
Email, LINE, Slack notifications arrive reliably, simple replies possible
📞 Call Function
Good voice quality, practical as hands-free calling
💳 Payment Function
Garmin Pay supported, but compatible stores limited in Japan
🔄 Sync Speed
5-10 seconds sync with Garmin Connect app, smooth data reflection
After one month of use, my awareness and actions regarding health management changed fundamentally. Through data-based objective health management, what was previously intuitive physical condition management transformed into a scientific approach.
⏰ Hourly Move Alerts
Light vibration notification when continuous sitting exceeds 50 minutes, promoting standing up
📈 Activity Visualization
Daily steps increased from average 6,500 to 8,200 steps (26% improvement)
🚶♂️ Conscious Behavior Changes
Accumulation of small improvements like changing elevators to stairs, choosing distant parking
📊 Stress Level Quantification
Objective view of current stress state on 0-100 scale, average value 32 (low stress)
🧘♂️ Breathing Exercises
Automatic breathing technique suggestions during high stress (60+), values improve through practice
💡 Pattern Recognition
Discovered stress increase patterns before/after meetings and during late-night work, implementing preventive measures
🏃♂️ Three Times Weekly Running Habit
Accurate distance and pace measurement through GPS function, increased sense of achievement and motivation to continue
🎯 Goal Setting Function
Weekly step goal of 50,000 steps, 85% achievement rate fostering healthy competitive spirit
📈 Physical Fitness Improvement Experience
VO2 Max improved from 42 to 44, reduced breathlessness when climbing stairs
Based on experience using both devices, I compared the specific differences by category.
