1. 1.85-inch AMOLED display

The display is one of the biggest highlights of the ColorFit Pulse 4.

It features a 1.85-inch AMOLED HD screen with a 390 × 450-pixel resolution. AMOLED technology gives the watch deeper blacks and stronger contrast compared with conventional LCD/TFT displays.

The relatively large screen also makes notifications, menus and fitness information easier to view.

If display quality is high on your list of priorities, the ColorFit Pulse 4 has a strong advantage over many basic LCD smartwatches in the same category.

2. Bluetooth calling

The ColorFit Pulse 4 supports Bluetooth calling, allowing you to make and receive calls directly from your wrist when connected to your smartphone.

The watch can display caller information and also supports call rejection.

This is particularly useful when your phone is in your pocket or you need to quickly answer a call without reaching for it.

However, it is important to remember that this is Bluetooth calling, not standalone cellular calling. Your smartphone needs to remain connected.

3. Bluetooth 5.3 connectivity

The ColorFit Pulse 4 uses Bluetooth 5.3 for connectivity.

Noise lists compatibility with smartphones running Android 9.0 or later and iOS 11.0 or later.

The watch works with the NoiseFit app, which handles pairing, synchronization and several watch settings.

4. Health monitoring features

The ColorFit Pulse 4 includes several health and wellness features, including:

• Heart-rate monitoring
• SpO2 monitoring
• Sleep monitoring
• Stress measurement
• Female health tracking
• Step tracking
• Calorie tracking

These features make the watch suitable for users who want to monitor general wellness and daily activity.

However, the readings should be considered for general wellness purposes rather than medical diagnosis. Noise itself provides troubleshooting guidance noting that factors such as loose fit, sweat and movement can affect heart-rate, SpO2 and stress measurements.

5. Sleep monitoring

The ColorFit Pulse 4 can track sleep and synchronize the information with the NoiseFit app.

One useful aspect is that the watch can continue measuring sleep even when it is not currently connected to the app. The data can be synchronized once the connection is restored.

For users interested in understanding their general sleep routine, this can be a useful addition.

6. Stress monitoring

The smartwatch also includes stress measurement.

This feature is designed to provide an indication of stress levels using the watch's sensors and related algorithms.

As with other wellness features, these readings should be treated as general indicators rather than medical assessments.

7. Up to 7 days of battery life

Noise claims up to 7 days of typical usage for the ColorFit Pulse 4.

The watch is also rated for up to 30 days of standby time. Noise specifies a charging time of approximately 2 hours.

Actual battery life can vary depending on how you use the watch.

Features such as all-day heart-rate monitoring, high screen brightness, frequent screen wake-ups, notifications and Bluetooth calling can increase power consumption. Noise specifically recommends reducing brightness, disabling automatic heart-rate monitoring and turning off unnecessary notifications or raise-to-wake functionality to improve battery life.

Is 7-day battery life realistic?

The 7-day figure should be viewed as a manufacturer-rated maximum under suitable usage conditions.

Heavy users may get less battery life, particularly if they frequently use calling, health tracking and the display.

Still, up to 7 days is respectable for a budget AMOLED smartwatch.

8. IP68 water resistance

The ColorFit Pulse 4 comes with an IP68 rating.

This provides protection against dust and water exposure during everyday use.

However, an IP68 rating does not automatically mean that the watch is suitable for swimming, diving or every type of water activity. Users should follow Noise's recommended usage conditions.

9. 100+ watch faces

Noise offers 100+ watch faces for the ColorFit Pulse 4.

The watch also supports cloud-based watch faces, giving users plenty of options for changing the appearance of the home screen.

You can select different designs depending on whether you prefer a traditional watch appearance, a fitness-focused layout or something more colorful.

10. AI voice assistant

The ColorFit Pulse 4 includes an AI voice assistant as part of its smart features.

This adds another layer of convenience for users who want to access voice-assistant functionality from their wrist.

The exact experience can depend on the connected smartphone and software support.

11. Music controls

The watch includes music controls, allowing you to control playback on your connected smartphone.

This can be convenient while exercising or when your phone is not immediately accessible.

12. Useful everyday features

The ColorFit Pulse 4 includes several additional functions, including:

• Caller name information
• Call rejection
• Alarm
• Timer
• Stopwatch
• Reminders
• Weather
• Calculator
• Music control
• Vibration alerts
• Do Not Disturb mode
• Screen brightness control
• Wrist-awake function

These features help make it more useful as an everyday smartwatch rather than simply a fitness tracker.

13. Functional crown

The watch features a functional crown, which provides another way to interact with the interface.

A physical control can make navigating menus more convenient than relying entirely on touchscreen gestures.

Noise ColorFit Pulse 4 performance

The ColorFit Pulse 4 is primarily designed as an everyday smartwatch rather than a premium sports watch.

Its strengths are the AMOLED display, Bluetooth calling, basic health monitoring and long battery life.

The watch should work well for users who mainly want to:

• Check notifications
• Answer quick calls
• Track steps
• Monitor basic health metrics
• Track sleep
• Check the weather
• Control music
• Customize watch faces
• Use everyday smartwatch functions

Users looking for advanced GPS, professional sports tracking or highly accurate medical measurements may need to consider a more advanced smartwatch.
