The Apple Watch Series 4 marked a major leap forward in the evolution of smartwatches. Released in 2018, it introduced significant design changes, enhanced performance, and new health-focused features that set it apart from its predecessors. For those who prefer a more compact form factor, the 40mm version of the Apple Watch Series 4 offers the perfect balance of size, comfort, and functionality. Whether you’re considering buying one or already own it, this comprehensive guide will cover everything you need to know about the Apple Watch Series 4 40mm, including its key features, design, health and fitness capabilities, and how it stacks up in 2024.
Key Features of the Apple Watch Series 4 40mm
1. Larger Display
One of the most notable changes in the apple watch series 4 40mm is the larger display, especially when compared to the Series 3. The Series 4’s screen is around 30% bigger, thanks to its edge-to-edge design with thinner bezels. The 40mm version has a 1.57-inch display that offers a significantly enhanced user experience, making text easier to read, apps more accessible, and overall interactions more fluid. The LTPO (Low-Temperature Polycrystalline Oxide) OLED Retina display also supports Force Touch and delivers vivid colors with impressive brightness levels, making it visible even in bright sunlight.
2. Redesigned Body
The Apple Watch Series 4 40mm maintains the iconic rectangular shape of its predecessors but is slightly thinner and more rounded. This redesign gives it a sleeker appearance, making it more comfortable to wear throughout the day. The 40mm size is perfect for users with smaller wrists or those who prefer a more compact watch face. Its lightweight aluminum or stainless-steel casing is durable enough for everyday wear while being stylish enough for formal occasions.
3. New Processor and Performance
Powered by the S4 chip, a 64-bit dual-core processor, the Apple Watch Series 4 is twice as fast as the Series 3, ensuring smooth operation and quick app launches. Whether you’re tracking a workout, answering a call, or using third-party apps, the performance remains seamless. Additionally, the W3 wireless chip enables more stable Bluetooth and Wi-Fi connectivity, and the GPS capabilities allow precise location tracking for outdoor activities like running, cycling, and hiking.
Health and Fitness Featuresapple watch series 4 40mm
The Apple Watch Series 4 40mm brings a wealth of health and fitness features, further solidifying Apple’s commitment to creating a smartwatch that can double as a powerful health tool. Some of the most groundbreaking features include:
1. ECG Monitor
One of the standout features of the Apple Watch Series 4 is its FDA-cleared electrocardiogram (ECG) monitor. By placing your finger on the Digital Crown, you can take an ECG in just 30 seconds, detecting any irregular heart rhythms, including atrial fibrillation (AFib). This feature has been a game-changer for users who want to monitor their heart health more closely. While it’s not a replacement for professional medical advice, it offers an easy and convenient way to track heart health over time.
2. Fall Detection
Another innovative feature introduced with the Apple Watch Series 4 is fall detection. Using an advanced accelerometer and gyroscope, the watch can detect when the wearer has fallen. If a fall is detected and no movement is registered for one minute, the watch automatically contacts emergency services and sends a message to your emergency contacts. This feature is particularly useful for seniors or individuals with mobility issues, offering an added layer of safety.
3. Improved Heart Rate Monitoring
In addition to the ECG, the Apple Watch Series 4 includes an upgraded optical heart rate sensor that continuously monitors your heart rate throughout the day. It alerts you if it detects abnormally high or low heart rates, which could signal potential health issues. The Series 4 also supports heart rate variability tracking, which can give insights into stress levels and overall cardiovascular health.
4. Fitness Tracking
As with previous versions, the Apple Watch Series 4 excels in fitness tracking. Whether you’re running, swimming, or practicing yoga, the watch provides real-time stats like calories burned, distance, pace, and heart rate zones. It also includes automatic workout detection, meaning it will start tracking your activity even if you forget to manually start a workout. The watch is water-resistant up to 50 meters, making it ideal for swimming and water-based workouts.
5. Activity Rings
The popular “Activity Rings” feature continues with the Series 4, encouraging users to close their Move, Exercise, and Stand rings every day. These rings track your daily movement, exercise minutes, and how often you stand throughout the day. The Series 4 also introduces enhanced coaching features, including personalized challenges and the ability to share your progress with friends for some friendly competition.
Battery Life and Charging
One of the main concerns for smartwatch users is battery life, and the Apple Watch Series 4 40mm performs admirably in this regard. Apple estimates that the Series 4 offers 18 hours of battery life on a single charge, which is typically enough to last a full day of use. However, heavy usage of features like GPS, cellular connectivity, or prolonged workouts can reduce battery life. Charging is done wirelessly using the included magnetic charging cable, and it typically takes around two hours for a full charge.
watchOS Compatibility
The Apple Watch Series 4 was initially launched with watchOS 5, but it remains compatible with the latest versions of watchOS. This means that, as of 2024, the Series 4 can still run watchOS 10, giving users access to the latest features, apps, and performance improvements. While the Series 4 may not receive software updates indefinitely, its current compatibility ensures it will remain a functional and capable device for years to come.
How the Apple Watch Series 4 40mm Stacks Up in 2024
While Apple has since released newer models, including the Series 5, 6, 7, and 8, the Apple Watch Series 4 40mm remains a solid choice for many users. Its key features, like the larger display, ECG, and fall detection, continue to make it relevant and useful, especially for those who prioritize health and fitness tracking. The Series 4’s performance and software compatibility also ensure that it can keep up with many modern tasks, making it a great value option for those who don’t need the latest model.
In terms of price, the Series 4 is more affordable than newer models while still offering many of the same core features. Whether you’re purchasing it second-hand or through a discounted retailer, the Series 4 represents a cost-effective solution without compromising on performance.
Conclusion
The Apple Watch Series 4 40mm is a feature-packed smartwatch that balances style, performance, and functionality. With its larger display, improved heart health features, and fitness tracking capabilities, the Series 4 continues to hold its ground in the wearable tech market in 2024. If you’re looking for a smartwatch that offers powerful health tools, seamless integration with the Apple ecosystem, and a sleek design, the Series 4 is still worth considering.
