As smartwatches continue to evolve, ZDNET has refined its testing methods to evaluate these devices rigorously. In 2026, the publication assesses smartwatches not just as accessories but as essential tools for health, fitness, and daily communication. With advanced features like voice assistants, crash detection, and extensive app suites, modern smartwatches have established themselves as vital companions for many users.
To ensure a thorough evaluation, ZDNET typically purchases smartwatches after their public release, allowing for an extended testing period. This approach means that reviews are based on comprehensive usage rather than a brief snapshot. Smartwatches undergo a minimum of two weeks of continuous wear to accurately measure battery life, health tracking capabilities, GPS accuracy, heart rate sensor reliability, and overall design.
The testing process is enhanced by ZDNET’s established relationships with major smartwatch brands. These partnerships facilitate direct inquiries regarding hardware, software, and specific functionalities, offering deeper insights into each device. While ZDNET tests a selection of third-party applications, the vast number of available apps means user experiences may differ widely.
User experience can also be influenced by various factors, including wrist size, the fit of the band, the smartphone used for connectivity, and even cellular reception quality for connected models. ZDNET provides a transparent perspective based on their testing with larger wrist sizes and various phone models.
Key Evaluation Criteria for Smartwatches
While price and battery life are factors in recommendations, they are not the primary considerations. Most smartwatches fall within the $300 to $500 range and typically require daily charging, especially models designed for fitness that offer longer battery life. Instead, ZDNET bases its recommendations on five critical evaluation factors: core functionality and performance, build quality and durability, health and wellness features, application support, and advanced functionalities.
Core functionality and performance are vital for a smartwatch to be deemed effective. It should reliably display the time and notifications while providing seamless integration with the user’s smartphone. Smartwatches now offer customizable watch faces that enhance usability and personalization. Features such as voice-to-text have significantly improved, allowing users to respond to notifications efficiently. ZDNET assesses how well these core functions operate under various conditions, including connectivity with multiple smartphone models and the consistency of notifications.
Build quality and durability are equally important. Most smartwatches today feature water resistance, enabling users to wear them in various conditions without fear of damage. ZDNET tests for scratches and wear by exposing the devices to different environments, including physical activities and inclement weather. The materials used in watch construction—like aluminum, stainless steel, and tough glass—are scrutinized to ensure they meet durability standards.
Health, Applications, and Advanced Features
Health and wellness tracking capabilities have become a significant focus in smartwatch development. Advanced features that were once exclusive to dedicated health devices have now been integrated into smartwatches, making them valuable tools for both casual and professional athletes. The Apple Watch, for example, continually introduces new health features that enhance user experience and performance tracking. With the latest updates in watchOS 11, Apple aims to maintain its competitive edge.
Additionally, ZDNET evaluates applications extensively. The early limitations of third-party applications have been addressed by major players like Apple, Google, and Samsung, who now offer a wide array of optimized apps for smartwatches. ZDNET employs a core set of applications during testing to gauge performance across different devices, noting that while Google’s offerings have improved, they still lag behind Apple in terms of functionality depth.
Advanced features often add intrigue to the review process. In 2025, satellite connectivity emerged as a key differentiator among smartwatches, with options for emergency services available even outside cellular range. ZDNET highlights other features such as LED flashlights, automatic interfaces for aquatic activities, and incident detection capabilities as vital components of modern smartwatches.
Today’s smartwatches embody significant technological advancements, offering users a wealth of options tailored to their needs. ZDNET’s extensive testing methodology not only evaluates basic performance and functionality but also dives into the intricate details that define each device. The insights gained from these evaluations help consumers make informed decisions when selecting smartwatches that best suit their lifestyles.
