Apple Watch Series 3 Aluminum
- Affordable
- Reliable
- Core smartwatch features
- Wireless charging
- Smaller display
- Older processor
- Limited health features compared to Series 4
Apple Watch Series 4
- Larger, brighter display
- Faster performance (S4 chip)
- Improved health tracking (ECG)
- Modern design
- Higher price
- Battery life not significantly improved
Display Comparison
The Series 4 features a significantly larger (1.78-inch vs 1.57-inch) and brighter display with thinner bezels, offering a more immersive viewing experience. The edge-to-edge design of the Series 4 is a noticeable upgrade, making it easier to read notifications and interact with apps.
Camera Comparison
Neither the Series 3 nor the Series 4 have a built-in camera. This is a consistent design choice for Apple Watches.
Performance
The S4 chip in the Series 4 provides a noticeable performance boost over the S3. Apps launch faster, animations are smoother, and overall responsiveness is improved. While both watches handle basic tasks well, the Series 4 feels more fluid and modern.
Battery Life
While both offer roughly the same advertised battery life (around 18 hours), the Series 4's more efficient S4 chip and slightly larger battery can sometimes provide marginally better real-world performance. However, usage patterns heavily influence battery life.
Buying Guide
The Apple Watch Series 3 Aluminum is ideal for budget-conscious users who want basic smartwatch features like notifications, activity tracking, and Apple Pay. The Series 4 is perfect for those seeking a premium experience with a larger display, enhanced health tracking (ECG), and faster performance.
Frequently Asked Questions
❓ Is the Apple Watch Series 4 worth the extra cost?
If you value a larger display, faster performance, and advanced health features like ECG, then the Series 4 is worth the investment. However, if you're on a budget and primarily need basic smartwatch functionality, the Series 3 remains a viable option.
❓ Can the Series 3 receive software updates indefinitely?
Apple typically supports older devices with software updates for a few years. While the Series 3 will eventually stop receiving updates, it will likely remain functional for a reasonable amount of time.
