3. COROS PACE 3 vs PACE 4: Key Differences Explained
The specification table shows that the PACE 3 and PACE 4 share many capabilities, but several differences can noticeably affect everyday use. The most important changes involve the display, battery performance, sensor hardware, controls, and overall responsiveness.
Display: Practical MIP or Sharper AMOLED
The most visible difference is the screen.
The PACE 3 uses a 1.2-inch Memory-in-Pixel display. It remains visible continuously, performs especially well in bright sunlight, and consumes relatively little power. Its colors and resolution are modest, but the display is practical for runners who want to check pace, distance, or heart rate quickly without activating the screen.
The PACE 4 replaces this with a 1.2-inch AMOLED display. Text, charts, notifications, and activity data appear much sharper and more colorful. Automatic brightness adjustment also helps the watch adapt to different lighting conditions.
The tradeoff is power consumption. The PACE 4 can keep its display always on, but enabling that setting reduces estimated daily battery life from up to 19 days to approximately 6 days. For most runners, gesture activation offers the better balance between display quality and battery life. COROS confirms these display and battery specifications.
๐ก Display verdict: Choose the PACE 3 if you prefer an efficient, always-visible screen. Choose the PACE 4 if clarity, color, and a more modern interface matter more.
Battery Life: PACE 4 Leads in Advanced GPS Modes
Battery figures require careful comparison because COROS promotes different satellite modes for each watch.
The PACE 3 can last up to 38 hours in Standard GPS mode. However, when both watches are compared in similar advanced modes, the PACE 4 has a substantial advantage:
- In All Systems GPS mode, the PACE 3 is rated for up to 25 hours, compared with 41 hours for the PACE 4.
- In Dual Frequency mode, the PACE 3 is rated for up to 15 hours, compared with 31 hours for the PACE 4.
- With offline music playing, the PACE 4 also lasts longer in comparable GPS modes.
These gains are particularly relevant for long races, extended training sessions, and runners who frequently use Dual Frequency positioning in cities, forests, or other challenging environments. Actual battery life will depend on display settings, navigation, music, notifications, connected accessories, and satellite conditions. COROS provides the full estimates in its battery documentation.
๐ก Battery verdict: The PACE 3 remains sufficient for most daily training and common race distances, but the PACE 4 provides much more flexibility in its more accurate satellite modes.
GPS and Heart Rate Hardware
Both watches support All Systems satellite tracking and Dual Frequency positioning, so the PACE 3 already offers strong GPS capabilities for its price.
The PACE 4 introduces updated satellite hardware, which COROS says can establish a GPS connection more quickly. It also has a redesigned optical heart rate sensor intended to reduce abnormal spikes and drops in wrist-based readings.
That does not mean the PACE 3 suddenly becomes inaccurate. GPS and wrist heart rate performance can vary with location, watch fit, skin contact, weather, movement, and the type of workout. Runners who require the most dependable heart rate data during intervals or other rapidly changing efforts may still prefer a compatible external heart rate monitor.
๐ก Tracking verdict: The PACE 4 has the stronger hardware on paper, but the practical improvement will vary between runners and training environments.
Controls, Speed, and Voice Features
The PACE 3 uses the familiar COROS digital dial, Back/Lap button, and touchscreen controls in supported areas.
The PACE 4 adds a third physical control called the Action Button. During an activity, it can provide faster access to selected functions, including changing between activity data and navigation screens or recording a Voice Pin. The newer hardware also makes menus, graphics, and interactions feel more responsive.
A built-in microphone enables Voice Pins, training notes, and Voice Control. Voice Control can be used for supported commands such as starting an activity or checking selected information. However, it is currently a beta feature, supports English, and requires a connected phone with the COROS app running. It should therefore be considered a useful convenience rather than the main reason to upgrade. COROS explains the current Voice Control requirements.
๐ก Controls verdict: The PACE 4 offers the smoother and more convenient experience, particularly when interacting with the watch during a workout.
Size, Weight, and Charging
Despite the newer screen and hardware, the PACE 4 remains an exceptionally light running watch. It is only slightly larger and heavier than the PACE 3, so neither model should feel bulky during running or sleep tracking.
The PACE 3 is still the better choice for someone who specifically wants the smallest and lightest option. Its case measures 41.9 mm across, compared with 43.4 mm for the PACE 4.
Charging is also handled differently. The PACE 3 includes a dedicated charging cable, while the PACE 4 includes a compact COROS A2 adapter that connects to a standard USB-C cable. The adapter is easier to carry, although a USB-C cable may need to be supplied separately.
What Has Not Changed Significantly
๐ The PACE 4 improves the hardware experience, but it does not completely replace what the PACE 3 can do.
Both watches provide:
- Structured workouts and COROS training plans.
- Training load, recovery estimates, and Running Fitness insights.
- Race predictions and personalized marathon plans.
- Running, cycling, swimming, triathlon, strength, and other activity modes.
- Breadcrumb navigation with route and deviation guidance.
- Manually transferred MP3 music.
- Bluetooth accessory support.
- Access to the COROS app and Training Hub without a required paid subscription.
Neither watch provides full offline maps or native Spotify and Apple Music downloads. Runners primarily interested in training analysis will therefore find much of the same essential ecosystem on both models.
4. Which Watch Is Better for Your Running and Training?
For most runners purchasing a COROS watch for the first time, the PACE 4 is the better overall choice. Its AMOLED display, longer battery life in advanced GPS modes, updated sensors, faster interface, and additional controls make it the more complete long-term purchase.
However, the PACE 3 can still be the smarter choice when it is available at a meaningfully lower price or when its MIP display better suits the runnerโs preferences.
For Everyday Running and General Fitness
Both watches are more than capable of recording easy runs, tempo sessions, intervals, treadmill workouts, and everyday activity.
The PACE 3 offers nearly all the essential training tools most recreational runners need. The PACE 4 makes those tools easier and more enjoyable to use through its sharper display and faster interface, but it does not fundamentally change the training system.
Best choice: PACE 4 for the better overall experience. PACE 3 for better value.
For Marathon and Half Marathon Training
The two watches support structured workouts, training plans, recovery information, race predictions, and COROSโs personalized marathon tools.
The PACE 4โs longer battery life is not essential for a typical marathon, but it provides more room for long training weeks, navigation, advanced GPS use, and music without frequent charging. Its clearer display can also make workout instructions and multiple data fields easier to read while running.
Best choice: PACE 4, although the PACE 3 remains fully capable of supporting a marathon training cycle.
For Intervals and Performance-Focused Training
During intervals, hill repetitions, or track sessions, quick access to workout data matters. The PACE 4โs sharper screen, faster hardware, additional Action Button, and redesigned heart rate sensor can give it a practical advantage.
The PACE 3 still supports structured sessions and detailed performance metrics. Runners who use an external heart rate monitor may also find the difference between the watches less important.
โน๏ธ Best choice: PACE 4.
For Long Runs, Ultramarathons, and Extended GPS Use
The PACE 4 is the clear winner when long battery life in All Systems or Dual Frequency mode is a priority. Its 41-hour All Systems estimate and 31-hour Dual Frequency estimate offer considerably more flexibility than the corresponding PACE 3 modes.
For extremely long events, battery results still depend on settings and usage. Navigation, music, an always-on display, and connected accessories can reduce the published estimates.
โน๏ธ Best choice: PACE 4.
For Running in Bright Sunlight
The PACE 4โs AMOLED display is sharper, but the PACE 3โs transflective MIP screen is naturally well suited to bright outdoor conditions. It remains visible without requiring a wrist gesture and uses relatively little power.
Runners who prefer a traditional sports-watch display may consider this an advantage rather than an outdated feature.
โน๏ธ Best choice: PACE 3 for an always-visible MIP screen. PACE 4 for higher resolution and richer colors.
For Trail Running and Route Navigation
Both watches offer breadcrumb navigation, elevation profiles, deviation alerts, checkpoints, Back to Start, and turn-by-turn prompts on supported routes. Neither provides the detailed offline maps found on some higher-end GPS watches.
The PACE 4โs clearer display and longer advanced GPS battery life make it more convenient for following a route, but its navigation system remains breadcrumb-based.
โน๏ธ Best choice: PACE 4 between these two watches. If detailed offline maps are essential, neither model may be the ideal choice.
