Smartwatch with Calling Feature: 3 Common Buying Mistakes

A smartwatch that helps you navigate, tracks your health, and lets you make calls without reaching for your phone. It might sound like an expensive gadget, but it doesn't have to be. However, the market is flooded with models that promise a lot but disappoint in practice.

As a Product Recommendation Officer at Joybuy, I see daily which specifications truly make a difference. Before you make a choice, it's wise to know what to look for. Let's discuss the three most common pitfalls that can ruin your purchase.

  1. The "waterproof" lie: Many watches are promoted as waterproof, but the fine print tells a different story. A low IP rating means an unexpected downpour can be disastrous, let alone going for a swim.
  2. Unstable Bluetooth connection: A smartwatch with a calling feature is useless if the connection to your phone constantly drops. Cheaper chips and outdated software are often the culprits, resulting in dropped calls and missed notifications.
  3. Vague health data: A smartwatch with a heart rate monitor or smartwatch oxygen monitor is popular, but the accuracy of the sensors varies enormously. Without reliable hardware and a good app, the collected data is of little use.

What You Should Look For: The Most Important Specifications

To avoid making a bad purchase, there are a few technical features you should always check. These determine whether a smartwatch is worth its money.

1. Bluetooth Version and Connectivity

The calling feature lives or dies by its Bluetooth connection. Look for a model with at least Bluetooth 5.0. This version offers a more stable and longer range (usually up to 10 metres) and is more energy-efficient than older versions. This ensures your calls remain clear and the battery lasts longer. Also, check if the smartwatch is compatible with your phone, whether you have a smartwatch android or an iOS device.

2. The IP Rating for Water Resistance

Don't be fooled by the term 'waterproof'. The IP rating indicates exactly how well a device is protected.

  • IP67: Dustproof and can be submerged in water up to 1 metre deep for 30 minutes. Suitable for hand washing and rain.
  • IP68: Dustproof and can remain underwater for longer and at greater depths (the exact specifications vary by manufacturer). This is a better choice for a waterproof smartwatch if you plan to wear it while swimming in shallow water. Note: Most manufacturers advise against use in saunas, hot water, or the sea, as this can damage the waterproof seals.

3. Sensors and the Companion App

A sports watch or fitness tracker is only as good as its sensors. Features like a watch with a step counter, heart rate monitoring, and oxygen saturation (SpO2) have become standard. The quality depends on the sensor used. Also, look at the app that comes with the watch (such as Da Fit or GloryFit). A good app presents the data clearly, helps you discover trends, and gives you insight into your activities and sleep patterns. The measurements are intended for personal insights and do not replace medical advice.

Frequently Asked Questions

How long does the battery of a smartwatch with a calling feature last?

Battery life varies greatly by model and usage. Manufacturers often provide an estimate for 'normal use' (typically 5-7 days) and 'standby' (up to 30 days). Active use of the calling feature, GPS, and continuous heart rate monitoring will drain the battery faster. In practice, expect to charge it every 2 to 5 days.

Does a smartwatch with a calling feature work without a phone nearby?

Most affordable smartwatches use Bluetooth to connect to your phone for making calls. Therefore, your phone must be within range (usually about 10 metres). Models with their own eSIM card can make calls independently without a phone, but these are significantly more expensive and require a separate mobile plan.

Are the health measurements from an affordable smartwatch reliable?

The sensors in modern, affordable smartwatches have improved significantly in recent years. They provide a good indication of your heart rate, steps, and sleep patterns, which is useful for tracking your lifestyle. However, it's important to remember that these watches are not medical devices. Use the data as a guideline for your well-being, not as a medical diagnosis.
