Apple Watch 3 Vs 4 Buying Guide

Design and Build Quality

The Apple Watch Series 3 features a design that has aged gracefully, still offering a comfortable fit and familiar aesthetic. It’s available in aluminum, with options for GPS or GPS + Cellular connectivity. The Series 4, on the other hand, boasts a significantly redesigned appearance, with a larger display and thinner bezels, maximizing screen real estate within a similar overall footprint. It also introduces a more refined, premium feel, especially in the stainless steel and ceramic models, showcasing a step up in build quality and aesthetics. The rounded corners and curved display of the Series 4 contributes to its modern look.

Display Technology and Size

One of the most apparent differences is the display. The Apple Watch Series 3 offers a smaller display with thicker bezels, which can feel somewhat cramped compared to modern smartwatches. The Series 4 introduces a larger display, with over 30% more screen area, thanks to the reduced bezels and the curved corners. This allows for more information to be displayed at once, making it easier to read notifications, view complications, and interact with apps. The Series 4 also features a brighter display, enhancing visibility, especially in direct sunlight. (See Also: Demeyere 5 Plus Vs Atlantis )

Performance and Speed

The Apple Watch Series 4 packs a more powerful processor, the S4 SiP (System in Package), compared to the Series 3’s S3 SiP. This translates to noticeable improvements in speed and responsiveness. Apps launch quicker, animations are smoother, and the overall user experience feels snappier on the Series 4. The improved performance is particularly evident when multitasking or running demanding applications. The Series 3, while still functional, may experience occasional lag or delays in comparison.

Health and Fitness Features

Both watches offer comprehensive health and fitness tracking capabilities, including heart rate monitoring, activity tracking, and workout modes. However, the Apple Watch Series 4 introduces several advanced features. The Series 4 includes an ECG (electrocardiogram) app for detecting atrial fibrillation (AFib), and fall detection, which can automatically call for help if it detects a hard fall. While the Series 3 offers similar tracking for basic activities, it lacks these advanced health-monitoring functions.

Connectivity and Battery Life

Both models offer GPS and cellular connectivity options, allowing you to stay connected even without your iPhone nearby. In terms of battery life, both watches are rated for all-day usage. However, the larger display and more powerful processor of the Series 4 might result in slightly reduced battery life under heavy use. In typical usage scenarios, you can expect similar battery performance from both models, often requiring charging at the end of the day. Cellular models generally consume more power.

Price and Value Proposition

The Apple Watch Series 3 is typically available at a lower price point, making it an attractive option for budget-conscious buyers. It offers a solid set of features and remains a capable smartwatch. The Apple Watch Series 4, being a more premium product, comes with a higher price tag. However, the improved display, performance, and advanced health features offer significant added value. The decision depends on your budget and the features you prioritize, with the Series 3 offering great value and the Series 4 providing a more premium experience. (See Also: Nikon 50 1 8 Vs 1 4 )
